Cheapest Email Marketing Platform: What Actually Works

The Pricing Page Lie You Need to Understand First

Every email marketing platform looks cheap on the homepage. Then you go to upgrade, your list hits 5,000 contacts, and suddenly you're paying triple what you expected. I've been through this with multiple businesses - from solo newsletter to agency to SaaS - and the game is always the same: bait you in cheap, then scale the price faster than your revenue scales.

So before I break down the actual cheapest options, understand one thing: there are two completely different pricing models in this space, and mixing them up is what causes sticker shock.

• Contact-based pricing - you pay based on how many subscribers are on your list, regardless of how many emails you send. Examples: Moosend, MailerLite, AWeber, Mailchimp.
• Volume-based pricing - you pay based on how many emails you send per month, not list size. Examples: Brevo (formerly Sendinblue), Mailjet.

Which model is cheaper for you depends entirely on your sending frequency. If you blast your list three times a week, volume-based pricing will wreck you. If you have a big list but only send once or twice a month, volume-based pricing can save you serious money. Know your own numbers before you pick a tool.

There's one more thing to get straight before we go platform by platform: the word "cheap" is deceptive on its own. The number that matters is cost-per-result, not cost-per-month. A platform that costs $9/month but lets 17% of your emails rot in spam folders is objectively more expensive than a $20/month platform with strong deliverability. I'll call both the price and the deliverability story out for each tool below.

How to Calculate Your Real Platform Cost Before You Sign Up

Here's the exercise most people skip. Before you look at a single pricing page, write down three numbers:

1. Your current list size (or where you realistically expect to be in 6 months)
2. Your monthly send frequency (how many times per month do you email your full list?)
3. Your expected list size at 12 months

Now multiply list size by send frequency to get your monthly email volume. That single number tells you whether contact-based or volume-based pricing is cheaper for you. If you have 8,000 subscribers and you send 4 times a month, you're sending 32,000 emails per month - that's the number you price shop against, not just "8,000 subscribers."

Most people skip this and pick based on the lowest headline price. Then they hit their first list milestone, upgrade plans, and wonder why they're paying double. Map the math before you commit.

The Actually Cheapest Options Right Now

Let's go platform by platform. These are the ones worth your time if you're watching the budget.

Brevo - Best for Large Lists, Low Send Frequency

Brevo is the closest thing to a true value play if you have a big list but don't hammer it constantly. Their free plan includes 9,000 emails per month and up to 100,000 contacts - that's a legitimate free tier, not a demo. Paid plans start at $9/month for 5,000 emails with no daily sending limit.

The catch: Brevo's Starter plan puts their branding on your emails. Remove it and you're adding to your monthly cost. Factor that in before you get excited about the $9 headline. There's also the SMS and WhatsApp angle - those channels aren't included in email plans, they're metered separately, so a multichannel campaign lands on a second bill.

Where Brevo wins is scale. Their pricing is flat relative to contact count - it doesn't matter whether you have 5,000 or 100,000 contacts, you're paying based on email volume sent. For high-volume lists you email sparingly, that's a significant advantage over contact-based competitors. They also include marketing automation, CRM, and web tracking on most plans without additional fees, which adds genuine value versus platforms that gate those features behind higher tiers.

The hidden cost watch-out on Brevo: dedicated IP is an extra charge not bundled even on higher plans, and the branding removal is an add-on on the Starter tier. Run your fully-loaded cost before comparing it to competitors.

Moosend - Best for High Send Frequency

Moosend starts at $9/month for 500 contacts with unlimited email sends on every paid tier. That "unlimited sends" part is the whole story. If you email your list frequently - multiple times a week - Moosend's subscriber-based, unlimited-send model becomes dramatically cheaper than volume-based alternatives as your cadence increases.

Moosend's automation builder is genuinely capable at this price point. You can build sophisticated workflows with multiple conditions and actions - not just basic drip sequences. A/B testing, landing pages, and reporting are all included at the entry level, not locked behind premium tiers. The UX is well-designed and intuitive, which matters when you're a small team and can't afford hours debugging an interface.

There's no forever-free plan, but a 30-day free trial gives you access to the full feature set. One underrated feature: Moosend lets you buy email credits instead of committing to a monthly subscription, which is useful if your sending is seasonal or inconsistent. For agencies and high-frequency senders watching every dollar, Moosend consistently delivers strong value.

MailerLite - Best for Beginners Who Want to Stay Cheap Long-Term

MailerLite has a clean interface, minimal learning curve, and a pricing structure that's genuinely beginner-friendly. Their free plan has been adjusted recently - the subscriber limit on the free tier has come down from earlier levels, so check the current free plan specifics on their site before assuming what you'll get for nothing.

Their paid entry plan is competitive in the contact-based tier, includes landing pages and a website builder (which Brevo doesn't include on lower plans), and doesn't gate basic automation behind expensive upgrades. If you want a tool you won't outgrow in six months but also won't scare you on day one, MailerLite is a solid pick. It's particularly strong for creators, bloggers, and small publishers who want clean newsletters without operational overhead.

One thing to note: MailerLite has changed their free plan limits more than once in recent memory. If you're planning around free-tier features, build in the assumption that the free plan could tighten again. Committing to a paid plan early actually gives you more stability in what you're getting.

EmailOctopus - Best Free Tier for Newsletters

EmailOctopus is a name that doesn't show up in enough of these comparisons. Their free plan gives you 2,500 subscribers and 10,000 emails per month - that's genuinely competitive, not a crippled demo. Paid plans start around $8-10/month and scale with list size, often at a fraction of what larger-name competitors charge. At 10,000 subscribers, they sit comfortably in the budget tier among all serious competitors.

The trade-off is deliberate simplicity. EmailOctopus keeps costs down by focusing purely on email - no SMS, limited automation depth, and a more basic template library than platforms like Sender or MailerLite. Think of it like a reliable workhorse: it does email well and cheaply, and doesn't try to be a full marketing suite. If you're a blogger, creator, or solopreneur running simple broadcasts and basic drip sequences, EmailOctopus is worth a serious look.

One technical note: EmailOctopus also offers a "Connect" plan where you link your own Amazon SES account, which can dramatically reduce costs for high-volume senders - but it requires technical setup. If you're comfortable with AWS, this can be the cheapest per-email cost in the entire market. If you're not technical, stick with the standard plan.

Sender - Best Automation-to-Price Ratio Under $20

Sender is another platform that gets overlooked because it doesn't have the brand recognition of Mailchimp or Brevo - but it consistently shows up as one of the most affordable options at every list size when you run actual cost comparisons. Their free plan covers up to 2,500 subscribers with a solid email volume allowance, and automation, segmentation, and transactional emails are included even on lower-paid tiers. They also include SMS marketing on their paid plans, which most entry-level email platforms charge extra for or don't offer at all.

The gap between Sender and EmailOctopus in terms of feature depth is meaningful if you need things like multi-step automation, SMS, or a large template library. If you just need clean email broadcasts with basic automation at the lowest possible price, either works. At the 10,000-subscriber mark, they're within a few dollars of each other monthly - so features, not price, should drive the decision between them.

AWeber - Free Tier Worth Knowing About

AWeber offers a free plan covering a limited number of subscribers with a set monthly email allowance, plus access to a large template library. Their entry paid plan starts at $15/month. The free plan is genuinely functional - not a crippled demo. The analytics are less sophisticated than Mailchimp's, but if you don't need deep reporting and you're budget-constrained, AWeber's free tier is one of the more usable no-cost starting points in the market.

AWeber also has a well-established affiliate program if you want to layer in monetization from day one - you can check out the AWeber setup here. It won't make you rich, but for early-stage operators trying to offset tool costs, it's a legitimate option.

Zoho Campaigns - The Actual Cheapest Entry Point

If raw cheapness is the goal, Zoho Campaigns' Standard plan at $4/month is hard to beat on headline price. It's part of the broader Zoho ecosystem, so if you're already using Zoho CRM or Zoho Books, the integration is seamless and saves you from paying for connectors. The trade-off is a steeper learning curve and a less polished experience than MailerLite or Brevo. But for a scrappy bootstrapped operation where every dollar matters, $4/month is real money saved across a year.

The honest caveat: Zoho's interface isn't going to win any design awards, and the onboarding experience is clunkier than competitors that have invested more in UX. If your team spends three hours getting the tool set up, you've already burned your "savings" in time cost. But if you're already in the Zoho ecosystem or you're genuinely price-constrained and willing to invest setup time once, it's worth considering.

Mailchimp - The Platform You Probably Already Know, And Probably Shouldn't Use

Mailchimp gets mentioned in every list like this, so let's get it out of the way quickly. Their free plan has been reduced to 250 contacts, with no automation at all. They continue to bill for unsubscribed and inactive contacts unless you manually archive them, which inflates your billed contact count significantly compared to competitors who don't charge for unsubscribed users. Paid-tier prices have stepped up significantly over the past few years.

None of this means Mailchimp is bad - it's just not cheap anymore, and the historical counting issue catches people off guard. If you're already on Mailchimp and considering migrating to save money, most platforms have import tools that make the switch straightforward. Run the math on what you're actually paying versus what you'd pay on Brevo, Moosend, or MailerLite at your list size. The savings are often real enough to justify the one-time migration effort.

Instantly and Smartlead - If You're Doing Cold Outbound, Not Newsletters

One important distinction most "cheapest email marketing" comparisons skip: there's a massive difference between email marketing platforms (newsletters, nurture sequences, broadcast campaigns to opted-in lists) and cold email platforms (outbound prospecting to people who don't know you yet). If you're running outbound sales - which is what I do and teach - you need completely different infrastructure.

For cold email, Instantly and Smartlead are the tools I'd send you to first. They're built for high-volume cold outreach with inbox rotation, warm-up, deliverability monitoring, and sending limits designed around cold email best practices. Using a newsletter platform for cold outbound is a deliverability disaster waiting to happen - these tools have fundamentally different sending infrastructure, compliance requirements, and relationship dynamics with inbox providers.

The reason this matters: Gmail now requires SPF, DKIM, and DMARC authentication, spam complaint rates below 0.3%, and one-click unsubscribe for promotional messages. Microsoft followed with similar enforcement. If you send cold outbound through a newsletter platform not designed for that use case, you'll hit these walls fast. Use the right tool for the right job. I break down my full cold email stack in the Cold Email Tech Stack guide.

Head-to-Head Price Comparison by List Size

All these platform names mean nothing until you run the numbers at your actual list size. Here's how the major budget-friendly options roughly compare at three common list sizes. Note that pricing changes frequently - always verify current pricing on each platform's site before committing.

At 500 Subscribers

This is where free tiers dominate. EmailOctopus covers you entirely on their free plan (2,500 subscribers, 10,000 emails/month). Brevo's free plan covers you on volume if you're under 9,000 emails/month. AWeber has a functional free tier here. Moosend starts at $9/month since they don't have a free plan. MailerLite has a free plan that has been tightening over time - check current limits. Zoho Campaigns is cheapest on paid plans at $4/month.

Verdict at 500 subscribers: If you're on a budget, use EmailOctopus or Brevo's free tier. If you're willing to pay a small amount for a better experience, Moosend at $9/month gives you a lot of feature depth.

At 5,000 Subscribers

This is where pricing diverges meaningfully. Contact-based platforms start billing you for list size. Volume-based platforms like Brevo stay cheap if your send frequency is low. At 5,000 subscribers sending 2-3 times per month (10,000-15,000 emails/month), Brevo's volume pricing and Moosend's contact pricing are both competitive. MailerLite and EmailOctopus are in a similar range. Mailchimp starts to become noticeably more expensive here, especially if you have unsubscribed contacts sitting in your list inflating your bill.

Verdict at 5,000 subscribers: Run your actual email volume. If you send fewer than 4 times per month, Brevo is worth a serious look. If you send more frequently, Moosend or EmailOctopus on their paid tiers gives you unlimited sends for a flat contact-based fee.

At 10,000 Subscribers

At this size, the differences are real money. EmailOctopus on their Pro plan is around $44-45/month and sits comfortably in the budget tier. Sender is in a similar range. Brevo at this size stays competitive as long as you're not sending high-frequency campaigns - if you're emailing daily or multiple times per week, volume-based pricing starts to bite. Moosend scales predictably and includes unlimited sends. Mailchimp at 10,000 subscribers is significantly more expensive than most alternatives on this list, which is why Reddit threads and startup communities consistently recommend switching away as lists grow.

Verdict at 10,000 subscribers: EmailOctopus, Sender, and Moosend are your best bets on pure price. Brevo wins if your send frequency is low. Nobody at this list size should be paying Mailchimp rates unless they specifically need features none of the alternatives offer.

What "Cheap" Actually Costs You in Deliverability

The number that doesn't show up on pricing pages is deliverability rate. The average email deliverability rate across all platforms reaches only around 83%, meaning roughly 1 in 6 marketing emails never reaches the inbox. A $9/month platform landing 70% of your emails in the inbox is more expensive than a $20/month platform landing 95%, because you're paying for sends that never get seen.

This isn't theoretical. In independent third-party testing, inbox placement rates across platforms vary dramatically. Some budget platforms score above 90% - others score below 50%. Benchmark Email, for example, scored 47.1% inbox placement in one notable round of third-party testing, with major email providers blocking a significant portion of test messages. A platform like that isn't cheap at any price point if half your emails never arrive.

A few things to watch for on budget platforms:

• Shared IP addresses - most entry-level plans put you on shared sending infrastructure. If other users on that IP are spamming, your deliverability suffers. Some platforms let you add a dedicated IP as an upgrade; factor that cost into your real platform price.
• Branding signals - Brevo's Starter plan includes their branding, which can signal "bulk email" to spam filters. Removing the branding costs extra. That extra cost belongs in your total plan calculation.
• Free plan sending limits - Brevo's free tier caps you at 300 emails per day. Fine for testing, not for real campaigns. Know the daily limit, not just the monthly allowance.
• Authentication setup - SPF, DKIM, and DMARC setup is now effectively mandatory. Platforms vary in how much help they give you getting this right. A platform with poor onboarding around authentication will hurt your deliverability even if their infrastructure is fine.

Before you pull the trigger on any platform, run a test campaign through a free tool like Mail-Tester or GlockApps to check your inbox placement. The cheapest platform isn't cheap if half your emails end up in spam or go completely missing.

The Hidden Costs That Kill "Cheap" Deals

Before you commit to any platform, run through this checklist. This is where "cheap" platforms quietly get expensive:

• Automation gating - some platforms restrict automation workflows to higher-tier plans. Brevo includes automation on their Starter plan; Constant Contact and GetResponse don't at entry level. Always check what's actually in the entry plan, not just the marketing copy. If you need automation and it's only available on the next tier up, your real starting price isn't the headline.
• Contact-based price jumps - on contact-based platforms, every list milestone triggers a plan upgrade. Map out what you'll pay at 1K, 5K, and 10K subscribers before you sign up, not after. Some platforms have aggressive jump steps that make the per-contact cost spike sharply at certain thresholds.
• Duplicate contact billing - Mailchimp has historically counted the same email address across multiple lists as separate contacts. That can inflate your billed contacts significantly if you're not careful about list hygiene. Other platforms handle this more sensibly, but always check the FAQ on how your platform counts contacts.
• Branding removal fees - some platforms charge extra to remove their logo from your emails. EmailOctopus, Brevo Starter, and others fall into this category. That cost belongs in your "real plan price" calculation, not footnotes.
• Transactional email limits - if you need to send receipts, password resets, or other transactional messages, check whether those count against your plan's send limit or are priced separately. Some platforms handle transactional email separately entirely, which adds a second bill.
• Annual vs. monthly billing gaps - annual billing typically saves 15-25% across most of these platforms. If you know you're committing, pay annually. That alone can make a platform that looks more expensive on monthly billing actually cheaper annually than a "cheaper" competitor on monthly.
• Add-on features that should be standard - SMS, dedicated IPs, advanced segmentation, and even things like landing pages are sometimes add-ons rather than included features. Always build the fully-loaded plan cost, not just the base tier.

Free Plans: Which Ones Are Actually Usable

Not all free tiers are created equal. Some are genuine entry points for real businesses. Others are so restricted they're only useful for understanding the interface before you upgrade. Here's the honest breakdown:

Actually Usable Free Plans

EmailOctopus Free: 2,500 subscribers and 10,000 emails per month. This is a legitimate free plan that can run a real newsletter. The EmailOctopus branding shows in your emails on the free tier, but for someone just getting started, that's a reasonable trade for $0/month. Basic automation is available.

Brevo Free: 9,000 emails per month with up to 100,000 contacts stored, but a 300 email per day sending cap. The contact storage is genuinely generous - you can build a large list and start emailing before you need to pay. The daily cap is the constraint to manage around.

Sender Free: Up to 2,500 subscribers and a solid email volume allowance monthly. Automation and segmentation are included, which separates it from free plans that strip out core features to force upgrades.

Free Plans With Real Constraints

MailerLite Free: Has been reduced multiple times. Check the current subscriber limit before planning around it. The feature set on the free plan is reasonable, but the subscriber ceiling means you'll likely hit the paid tier quickly if your list is growing.

AWeber Free: Covers a limited subscriber count with a set monthly email allowance. Functional, but the list cap means it works best as a genuine starting point rather than a long-term free plan.

Mailchimp Free: 250 contacts with no automation. At this point, Mailchimp's free plan is primarily useful for testing the interface. It's not a meaningful free tier for any business actually trying to run email marketing.

The "Trial" Distinction

Moosend doesn't have a free plan but offers a 30-day free trial with access to the full feature set. That's actually more useful than a stripped-down free plan, because you get to test everything before you pay anything. For tools in this tier, I'd rather have a 30-day full trial than a permanently crippled free version.

Platform-Specific Features Worth Paying For

Picking the cheapest entry price is only half the decision. The features you need at your sending volume and list size should influence which tier you're actually on - because sometimes the $9/month plan won't do what you need, and the real cost is the next tier up.

Automation Depth

If you're building automated sequences - welcome series, re-engagement flows, behavioral triggers - the automation builder quality varies significantly across budget platforms. Moosend's automation is genuinely sophisticated for the price point, with multi-condition workflows that go well beyond basic drip sequences. MailerLite's automation is solid for straightforward welcome and nurture flows. EmailOctopus's automation is basic - good for welcome campaigns and simple drips, but not for complex conditional logic. Brevo includes automation on their Starter plan, which is a meaningful advantage over platforms that gate it behind premium tiers.

Segmentation

Most budget platforms include basic segmentation - segment by open behavior, location, tags. Where they differ is in how easy the segmentation UI is to use and how many conditions you can combine. If you're running targeted campaigns to different audience segments (which you should be - segmented campaigns consistently outperform broadcast blasts), test the segmentation interface during your free trial before committing.

Landing Pages and Forms

MailerLite includes landing pages and a website builder on their free and lower paid plans. Brevo doesn't include landing pages on their free or Starter plans. Moosend includes landing pages at the entry level. EmailOctopus includes basic web forms. If landing pages are part of your list-building strategy, factor this into your total cost - otherwise you're adding a separate landing page tool to your stack and paying twice.

Transactional Email

If your business sends order confirmations, password resets, or other automated transactional messages, check whether the platform handles this natively or requires a separate setup. Brevo handles transactional email well and is often cited as particularly strong in this area. EmailOctopus does not handle transactional emails in their standard plans - you'd need their Connect product linked to Amazon SES or a separate transactional service, which adds complexity and potentially cost.

Reporting and Analytics

Budget platforms vary significantly in reporting depth. Moosend has strong reporting capabilities relative to its price point. MailerLite has clean, usable analytics without being overwhelming. AWeber's analytics are less sophisticated than some competitors. If detailed campaign reporting matters to your decisions - open rates by segment, click maps, revenue attribution - test this feature specifically, not just the sending interface.

How to Actually Build a List Worth Emailing

The platform you pick matters less than having the right people on your list. A lot of people obsess over which tool to use and ignore the actual lead generation side of the equation. A perfect email platform with a garbage list gets you nothing.

For B2B, the fastest way to build a targeted list is to source it directly rather than waiting for inbound signups. That means pulling contact data from a B2B email database filtered by industry, title, company size, and location - so your first email goes to people who actually fit your ICP, not a generic newsletter signup list. Once you have those contacts, you can segment them, warm them up with value-driven content, and move them into whatever email platform you've chosen.

If you're doing local business outreach - say you're an agency targeting restaurants, contractors, or retail shops in specific cities - a Google Maps scraper can pull structured business contact data directly from local search results, which is faster than manual prospecting and more targeted than a generic list provider.

For ecommerce prospecting, ScraperCity's Store Leads tool pulls ecommerce store data so you can target online sellers by platform, category, or revenue range - useful if you're selling services or tools to ecommerce operators.

The sourcing side of the equation matters before the platform decision even applies. If you're not sure which tools to stack for the full lead-gen-to-email workflow, the Tools & Resources page has what I'm actually using.

List Hygiene: The Cost Nobody Talks About

Before you migrate to a new platform, clean your list. This is not optional if you care about deliverability and not paying for contacts who will never open your emails.

Here's why: on contact-based platforms, every unengaged subscriber you keep on your list costs you money - both in the higher plan tier you're paying for and in deliverability drag from contacts who never open anything. High unsubscribe rates and low open rates signal to inbox providers that your emails aren't wanted, which degrades your sender reputation over time and tanks your placement rates across the board.

The habit to build: run a re-engagement campaign to your cold subscribers every 90 days. Anyone who doesn't open or click in that window gets removed. Smaller, engaged lists consistently outperform larger, disengaged ones - and they cost less on contact-based pricing.

On the technical side, run your list through an email validation tool before importing into a new platform. This catches invalid addresses, role-based emails (info@, support@, etc.), and catch-all domains that will inflate your bounce rate. High bounce rates get accounts flagged or suspended on most platforms - and that suspension can happen before you even realize you have a problem. Clean the list before you send, not after you've already blown up your sender reputation.

When to Upgrade Your Email Platform (And When Not To)

One of the bigger mistakes I see people make is upgrading their email platform before they've actually outgrown it. They see a feature they want, they upgrade, and they're paying for a tool they're using at 20% of its capacity. Here's the framework I use:

Upgrade when:

• You've consistently hit the contact or email volume limits on your current plan for two consecutive months
• You need a specific feature (advanced automation, dedicated IP, SMS) that is only available on the next tier and you have a specific campaign it will enable
• Your deliverability on the shared IP is measurably hurting your results and a dedicated IP is the upgrade path
• Your list is growing fast enough that you can project when you'll hit the next tier anyway - lock in annual billing now before the upgrade forces you to monthly

Do NOT upgrade when:

• You're under the limits on your current plan and the upgrade is a "nice to have"
• You think more features will make you send better emails - they won't, good copy and list quality will
• A salesperson told you to (obviously)
• You're comparing yourself to what you think you "should" be using based on what bigger businesses use

Migrating Between Email Platforms: What You Need to Know

People treat platform migrations like major surgery. They're not. Every serious email marketing platform has a contact import tool that accepts CSV files. The basic migration playbook is:

1. Export your subscribers from your current platform (usually under "Audience" or "Contacts" - export as CSV)
2. Clean the exported list with an email validation tool before importing
3. Import into the new platform, mapping your fields (first name, email, tags, etc.)
4. Recreate your key automation sequences in the new platform
5. Set up and verify your domain authentication (SPF, DKIM, DMARC) in the new platform
6. Send a warm-up campaign to your most engaged segment first before blasting the full list

The last step is the one people skip. If you move to a new platform and immediately send to your entire list, you're starting with zero sending reputation on the new infrastructure. Warm up by starting with your most engaged subscribers (people who've opened in the last 30 days), then expand to 90-day openers, then your full list. This protects your deliverability through the transition.

Budget a day of actual work for the migration, not three weeks of deliberation. The migration is not the hard part. Picking a new platform is not the hard part. Writing emails that people want to open is the hard part - and no platform decision changes that.

The Cold Outbound vs. Email Marketing Distinction (Expanded)

I touched on this earlier but it deserves its own section because I see people waste money constantly by using the wrong category of tool.

Email marketing platforms - Brevo, MailerLite, Moosend, EmailOctopus, and everything else in this article - are built for sending to opted-in lists. These are people who signed up, confirmed their email, and consented to receive your messages. The entire deliverability infrastructure of these platforms is built around that premise. They monitor complaint rates, require list-cleaning, and have terms of service that prohibit cold outreach to purchased or scraped lists.

Cold email platforms - Instantly, Smartlead, and similar tools - are built for reaching out to prospects who have no prior relationship with you. They have inbox rotation (sending from multiple email accounts to avoid volume flags), built-in warm-up to establish sender reputation on new domains, per-day sending limits designed around cold outreach best practices, and deliverability tooling specific to the cold outreach use case.

If you use a newsletter platform for cold outreach, you will get your account suspended. It's not a matter of if, it's when. EmailOctopus, for example, explicitly reviews new accounts for signs of purchased lists and role-based addresses, which commonly appear when people import cold prospect lists. Most newsletter platforms have similar safeguards.

The reverse is also true: using a cold email platform for your newsletter is overkill and expensive. Use the right category of tool for the right use case. If you're doing both - running a newsletter to an opted-in audience AND doing outbound prospecting to cold contacts - you need both categories of tool, running on separate domains. That's not a bug, it's good practice: keep your newsletter domain clean and separate from your cold outreach domain.

For building the contact lists you need for cold outbound, you need to source prospect data before you pick a sending tool. That means finding email addresses, finding direct dials for cold calling, and validating what you have before you send anything. An email finder tool handles the prospecting side; then clean and validate the output before it touches your sending infrastructure. The Clone Apollo guide covers how to build a targeted prospect list from scratch, which is the first thing you need before any email platform - cold or warm - matters.

My Actual Recommendation Based on Where You Are

Stop looking for the one perfect answer. The cheapest email marketing platform depends on your situation, and it changes as you grow. Here's how I'd think about it:

• You're just starting and have under 500 contacts: Start on EmailOctopus's free plan or Brevo's free plan. Both are functional, not just trial versions. EmailOctopus gives you more subscriber room on the free tier; Brevo gives you more email volume flexibility. Don't pay for anything yet.
• You have 500-5,000 contacts and email regularly: Moosend at $9/month gives you unlimited sends and solid automation. MailerLite is the runner-up if you want a cleaner interface and landing page tools built in. EmailOctopus is worth comparing if you're disciplined about keeping your needs simple.
• You have a large list (10K+) but email it infrequently: Brevo's volume-based pricing is genuinely cheaper here. Run the math against Moosend and EmailOctopus at your actual send frequency before deciding. At low send cadence, Brevo's pricing model works in your favor.
• You have a large list (10K+) and email frequently: Moosend with unlimited sends, or EmailOctopus on their Pro plan. Both beat volume-based pricing at high cadence. Sender is a strong competitor here too, especially if you want SMS included.
• You're doing cold outbound: None of the above. Use Instantly or Smartlead. Completely different infrastructure requirement. And make sure your contact data is clean before you send - run your list through a dedicated email validation tool to protect your sender reputation and cut bounce rates significantly.
• You need CRM + email in one package and want cheap: Look at Zoho Campaigns if you're already in the Zoho ecosystem - the integration is seamless and the price is hard to beat. Otherwise, Brevo's paid plans include a basic sales CRM that works for simple pipeline management without adding a separate CRM bill.
• You want email + SMS from one tool: Sender includes SMS on paid plans. Brevo also offers SMS but charges separately. Most other budget email platforms don't touch SMS natively.

Annual billing typically saves 15-25% across most of these platforms. If you know you're committing to one, pay annually. That alone can make a slightly more expensive platform cheaper than a "cheaper" competitor on monthly billing.

The Right Metrics to Track (Not Just Open Rate)

Once you're set up on a platform and sending, most people default to watching open rate as the primary metric. It's not the most important one. Here's what actually matters:

• Deliverability rate - what percentage of your sends actually reach an inbox, not just "delivered" (which can mean delivered to spam). Test this periodically with a tool like Mail-Tester, not just by looking at the bounce numbers your platform reports.
• Click-to-open rate (CTOR) - of the people who opened your email, what percentage clicked something? This tells you whether your content is resonating, independent of how good your subject line is. A high open rate with a low CTOR means your subject lines are working but your body copy isn't.
• List growth rate vs. unsubscribe rate - if you're adding 100 subscribers a month and losing 90 to unsubscribes, you have a content problem. Watch the net growth number, not just raw additions.
• Revenue per subscriber - ultimately the only metric that tells you whether your email list is an asset. Divide your email-attributed revenue by your subscriber count. That number should be going up over time as your list quality and content improves.

Most budget platforms include enough reporting to track these metrics. Don't upgrade for fancier analytics until you've actually used the analytics you have.

Don't Let the Platform Choice Be the Bottleneck

I've seen people spend three weeks comparing email marketing platforms and zero weeks actually writing emails. The platform is a commodity decision. Pick one from this list that fits your list size and send frequency, migrate later if you need to - most platforms have import tools that make this straightforward - and spend your real energy on the list quality, the offer, and the copy.

The variables that move the needle on email marketing results are, in order: the quality of your list (are these people who actually want to hear from you?), the strength of your offer (is there a reason to click?), and the copy (does the email earn the read?). The platform determines whether the email arrives. The other three determine whether it works. A mediocre email through a perfect platform is still a mediocre email.

If you're serious about improving results on the outbound side - not just newsletters but actual prospecting and sales conversations from email - that's a different discipline and a different stack. I cover the outbound prospecting side in depth inside Galadon Gold for people who want hands-on implementation support beyond what a blog post can provide. For a deeper look at the tools I actually run for lead generation and outreach, check out the Clone Apollo guide - it covers how to build a targeted prospect list from scratch, which is the first thing you need before any email platform matters.
