Cold Email Proof, Fraud, and Deliverability

What caught my eye on cold email Twitter this week - the math that holds up, the drama worth watching, and the infrastructure warning most senders are ignoring.

Every week I monitor what's circulating in the cold email space on X. Some of it is genuinely useful. Some of it is hype dressed up as insight. And occasionally something surfaces that's worth a longer reaction. This week had all three. Let me walk through the ones that mattered.

The Beard Brand Math Nobody Is Talking About Correctly

@HenryCrochemoreView on X
Sat next to a guy on a flight from bali last week Owns a men's grooming brand doing $620k/month He runs zero meta ads zero google ads zero tiktok ads 100% of his revenue comes from cold email to a list of 280,000 men who searched for "How to grow a beard" in the last 18 months said he buys the data from a broker for $0.04 per record writes one email per week sends it to 40,000 people every Monday 30% open rate 1.2% click to checkout 0.4% buy Does the math: $120k revenue every monday from one email Never spent a dollar on facebook in his life

The saves-to-likes ratio here is telling. People are bookmarking this one because the math is clean and the model is repeatable. Let me add some context that most people in the replies are missing.

What this guy built is not a cold email operation in the traditional sense. It's a warm list built from intent data. People who searched "how to grow a beard" already have the problem. He's not convincing anyone they need a grooming product. He's showing up at the moment the problem is top of mind. That is a completely different conversion dynamic than blasting a generic list of business owners.

The 0.4% purchase rate sounds low until you do the math: 40,000 sends, 0.4% buy, and he's clearing $120k in a single Monday. That's not a cold email campaign. That's a media channel he owns outright. No platform risk. No algorithm changes. No CPM increases.

The part people are sleeping on: he pays $0.04 per record. His entire list of 280,000 contacts cost him $11,200. A single Monday's revenue is more than ten times that. That's the leverage that makes this model work, and it's completely replicable in any niche where search intent data exists.

If you want to build something similar, start with your lead data quality. A clean, intent-matched list beats a massive generic one every time. We built the ScraperCity B2B database specifically because most people are working from stale, unverified contact data and wondering why results are flat. The foundation matters more than the copy.

The $80K Chargeback Story

@MrColdEmailView on X
The self proclaimed "Cold Email King" just charged back over $80,000 from the man who ran his entire email infrastructure That man is me I seen the disputes hit my dashboard and I swear to god I laughed out loud Jack Bricknell. JN Jack. @jn_jackk I was the FIRST person to ever supply this man with large scale infrastructure. September 2025. Every campaign his little kingdom ever sent ran through systems I built And bro averaged a 0.001% reply rate on them Do u understand how rtarded you have to be to pull 0.001% on infrastructure that prints money for every single other person who touches it The king of cold email cannot write a cold email are you crazy are you dumb Oh ? The infrastructure was the problem ? Buddy I built my own verifier and tested ur little OmniVerifier against it, the tool doesnt verify sht, ur tech is fake ur results are fake ur crown is fake So instead of locking in and getting better at his ONE job this grown man went to Amex and reversed every invoice since day one Fcked me for $80K+ overnight, the person who kept his whole operation alive But His own coaching students came to me and told me this is literally what he teaches Pay every vendor with Amex so u can reverse it all once ur done using them Make ur own clients pay bank transfer ONLY so they can never get a cent back Collect 5 figures deliver nothing churn repeat Any rtard on earth can run 100% margins when stealing ur costs back is the business model that is called fraud son And my DMs bro My fcking DMs 10+ people in a few days with the same story word for word If ur his customer rethink who ur backing If he owes u money protect urself while u still can If he ran this same play on u, DM me and get ur records together, there is a serious case being built against him and his company and u may be able to recover Jacky I know ur reading this so read slow U cannot charge back a subpoena Full exposé next week. Everything goes public, receipts and all U got cocky and stole from the wrong one See u next week bud 🫡

I'm not going to take sides on an ongoing dispute I have no firsthand knowledge of. But the pattern being described here is real, and I've seen versions of it across the industry for years.

The specific mechanic worth flagging: paying vendors on credit card specifically so you can reverse charges after consuming the service. This is not a gray area. It's fraud. The fact that it's allegedly being taught as a business strategy inside a paid coaching program is what makes this genuinely alarming.

Here's the practical lesson for anyone running infrastructure, lead gen services, or cold email delivery: if a client insists on paying by credit card and refuses any other method, that's a risk signal. Large volume, recurring infrastructure work should have payment terms that reflect the relationship. Bank transfer, ACH, or wire for anything above a certain threshold is not unreasonable to require.

The 0.001% reply rate claim is separately interesting. Infrastructure alone has never written a cold email. If someone is blaming their deliverability provider for reply rates, they haven't diagnosed their actual problem. Reply rates are a copy and targeting problem first, infrastructure second. I've sent campaigns on identical infrastructure where one sequence pulled 8% replies and another pulled 0.3%. The sender and the offer are the variable, not the SMTP setup.

Rippling's Numbers Are the Permission Slip Everyone Needed

@termsheetinatorView on X
Rippling. $1B ARR. $16.8B Valuation. 50% of their demos came from OUTBOUND. Extremely bullish on cold-calling and cold-email. https://t.co/Q7cwWdU3fG
142 likes · 7 replies · 175 saves

50% of demos from outbound at $1B ARR. Not a scrappy startup. Not a no-name agency. One of the most well-funded SaaS companies in the world. The people declaring cold outreach dead are explaining why their pipeline is empty, not why the channel doesn't work.

I've helped more than 14,000 entrepreneurs generate over 500,000 sales meetings through outbound. The channel works. It has always worked. What changes is the execution required to make it work as inboxes get more crowded and deliverability standards tighten. But the channel itself is not going anywhere.

The Enterprise Deliverability Warning Most Senders Are Ignoring

@axtalksView on X
You have to be VERY careful when running cold email at enterprise lists in 2026. 25-45% of those inboxes sit behind a secure email gateway. (Barracuda, Mimecast, Proofpoint) Sending to secure email gateways drops your email before delivery. Sometimes you see high bounce rates, even on valid emails. In other cases, reply rates APPEAR fine and nothing bounces… Yet, your sends are disappearing. My ESP segmentation when the list skews enterprise: 1. Resolve every contact's email provider via Google DNS Resolver API 2. Tag the recipients sitting behind Barracuda / Mimecast / Proofpoint 3. Pull Google senders OFF those segments 4. Run the enterprise segment on aged Outlook plus SMTP only 5. Monitor 550 bounces on every spike If your list is mostly enterprise and you are still sending from Gmail senders, you are quite literally lighting money on fire. Proceed with caution.

This is the most technically useful post in this week's roundup and it has 80 likes while the drama posts have 1,700. That's how Twitter works. The practical stuff gets buried.

The core insight here is correct and underappreciated: enterprise inboxes are disproportionately protected by secure email gateways. If you're targeting companies with 500+ employees and running everything through Gmail senders, you are losing a significant portion of your send volume before it ever reaches a human. The silence you interpret as low interest is actually a delivery failure you can't see.

The fix is segmentation at the infrastructure level. Resolve MX records before you send. Tag the Proofpoint, Mimecast, and Barracuda recipients. Route them through aged Outlook or dedicated SMTP configurations that those gateways treat differently. This is not optional if enterprise is your target market.

For a complete breakdown of how to structure your sending infrastructure by list type, the Cold Email Tech Stack guide covers the tooling decisions in detail. And if you need validated, clean contacts before any of this matters, ScraperCity's email validator will catch the garbage before it hits your sending reputation.

The Gojiberry ARR Breakdown: What to Extract and What to Ignore

@pierreeliottlalView on X
Gojiberry AI just hit $3.5M ARR. 11 months ago we were at $0. This is the second SaaS I've built. The first one I sold at €500K ARR. This time, we moved faster. Here's exactly how we did it, so you can do it too. The core principle that changed everything: We used our own tool to grow our own tool. Gojiberry AI finds high-intent leads and engages with them automatically. We run it on ourselves. It works insanely well. Here's the full breakdown: 1) Outreach (the engine) - LinkedIn: 5 accounts, 30 connection requests + 30 DMs per account per day. Only targeting warm leads showing real intent. Connection acceptance rates and reply rates are insane when you do this right. - Cold email: 6,000 emails per day. 295,000 sent in 90 days. 900+ opportunities created. 41 domains, 123 inboxes, plain text only, no links, no images, 2-3 email sequences max. Total infra cost: ~$600/month. The offer is always the same: a valuable blueprint. No pitch. Just value first. 2) Inbound (the compound effect) - LinkedIn: 6 posts per day across 6 accounts. 6 days/week = lead magnet content. 1 day/week = founder story. Last 7 days: 788,187 impressions. - Reddit: 14.8M+ views in 12 months. - YouTube: Long-tail SEO content targeting competitor keywords. - SEO: 50K visitors/month and growing fast. 3) Paid ads - 10 LinkedIn influencer posts/week (~$500 each). - Facebook retargeting + acquisition 4) Demos 5-8 per day. ~70% close rate to free plan. Mostly sales teams. 5) UGC We post 1200 UGCs per month across social media. What actually worked: → Using our own tool on ourselves → High-intent outreach > cold outreach. Every single time. → Lead magnet posts on LinkedIn that generate thousands of comments. One post added $5K MRR in under 24 hours. Cost: $0. → Replying to every single comment. → Speed. Every delay kills momentum. → AI helping us do 10x more than we ever could alone. What's not working: - We need to delegate more The path from €0 to $3.5M ARR is not glamorous. It's 18-hour days, boring repetitive work, testing things that fail, and doing it all again tomorrow. But if you do the right things every day, good outreach, real value, fast follow-up, it compounds.

The numbers that actually matter here: 295,000 emails sent over 90 days, 900+ opportunities created, $600/month in infrastructure. That works out to roughly one opportunity per 327 emails sent. That's a real conversion rate from a real operator, not a screenshot of a dashboard from a three-email test.

The infrastructure setup is worth noting: 41 domains, 123 inboxes, plain text only, no links, no images, sequences capped at 2-3 emails. This matches exactly what I've been recommending for years. Plain text performs better than designed HTML in cold outreach. Short sequences outperform long drips. The people adding fancy footers and images to cold emails are optimizing for aesthetics while their deliverability quietly collapses.

The one thing I'd push back on: the framing that "high-intent outreach beats cold outreach every single time" is accurate but incomplete. High-intent outreach at this volume IS cold outreach. The distinction they're drawing is really between targeted cold email and spray-and-pray cold email. The channel is the same. The targeting discipline is what's different.

If you want to structure sequences like this, the Cold Email Follow-Up Templates page has the exact frameworks worth modeling.

Daniel Fazio's Take on Performance-Based Cold Email

@realcolegordonView on X
I asked Daniel Fazio what he'd do if he was starting from zero with no money and no case studies. His answer was performance-based cold email, and his reasoning was great: "Cold email is for poor people. What I mean is it's very cheap. You can send tens of thousands of emails a month for maybe 500 bucks. You're only going to cap out at a couple clients a month, but it's so easy to go to a client and say, pay me a $500 tech fee and $300 for every call I give you. There's no ad spend, no upfront risk for them. And you can cold email to land those clients too, for less than $500 a month." Full clip below 👇

"Cold email is for poor people" is the most useful reframe of this channel I've heard in a while. He means it as a compliment. Low barrier, low ongoing cost, no platform dependency, no ad spend. You can build a legitimate outbound system for less than the cost of a gym membership and close clients who pay multiples of that per month.

The performance-based model he describes, a flat tech fee plus per-booked-call payment, is exactly the right entry structure for anyone who has no track record. It removes the client's risk entirely. If you can't close at least a few calls per month with $500 in infrastructure, the answer is your copy and targeting, not the channel. And if you CAN produce calls, the model scales cleanly.

I teach this same concept in the Cold Email Manifesto: start with a structure where your incentives are aligned with the client's outcome. It builds trust faster than any retainer pitch and it forces you to get good at the fundamentals quickly, because you only get paid when something works.

AI Results: The One That Has Real Numbers

@vertexxaiView on X
HE BUILT AN AI SALES AGENT THAT BOOKED 127 MEETINGS IN 30 DAYS. WITHOUT WRITING A SINGLE EMAIL. A 24-year-old founder was spending hours every day searching for leads, writing cold emails, and following up with prospects. Instead of hiring a sales team, he decided to build an AI agent. The system scanned thousands of companies, identified qualified leads, researched each business, and wrote personalized outreach based on hiring, funding, and recent activity. If someone replied, another AI agent handled the conversation, answered common questions, and only notified him when it was time to jump on a call. The results after just one month were impressive: 18,400 companies analyzed. 1,276 personalized emails sent. 412 replies. 127 booked meetings. 31 new clients. His total AI costs were under $450 for the month-far less than hiring a full-time sales rep.

The numbers in this post are worth examining carefully. 1,276 emails sent, 412 replies, 127 booked meetings. That's a 32% reply rate and a 10% meeting-booked rate on emails sent. Those numbers are not typical cold email performance. They are what you get when you send to extremely warm, highly targeted contacts with personalization built from real signals like hiring activity and funding announcements.

This is not an AI story. This is a targeting and intent data story. The AI is the execution layer. The reason it worked is that 18,400 companies were analyzed to produce 1,276 sends. That's a 1-in-14 filter rate. He threw out 93% of potential contacts before sending a single email. That level of selectivity is what drove those reply rates, not the AI writing the copy.

$450 in AI costs for 31 new clients is a remarkable number. The real cost was the system build time. But the lesson is transferable: tight targeting with signal-based personalization outperforms volume every time, whether you're using AI or doing it manually.

The iMessage Outreach Tactic

@Aje_DynamiczView on X
Since a lot of people asked, here's the "hack." The feature is iMessage on iPhone. And here's how it works... If you have a prospect's phone number (not just their email), save the contact and start a new message. If the message box turns blue 🔵, that number is registered with iMessage (meaning they're using an Apple device). If it stays green 🟢, they're not on iMessage. For prospects on iMessage, you can send a short, personalized pitch directly to them. What makes this different is that your message appears as a notification in their Messages app almost immediately, making it much more visible than a traditional cold email. Unlike emails, which can end up in the Promotions or Spam folder or sit unread in a crowded inbox an iMessage is more likely to be seen quickly because it arrives alongside the person's regular text conversations. PS...This doesn't replace cold email, it complements it. Many business owners, especially in the US, check their text messages much faster than their inbox, so it can help you get a quicker response. I've seen this work well for industries like Real Estate eCommerce Med Spas Home services Other small businesses One of the best places to find these business owners is inside Facebook groups, local community groups, business directories, and similar communities.

The saves number here (518 on 271 likes) tells you people are treating this as a tactic to actually use rather than just something to scroll past. The mechanic is real. If you have a mobile number, you can check iMessage status manually before sending.

Where I'd add caution: this tactic has a short shelf life at any meaningful scale. The reason it works is that people don't expect pitches in their Messages app. The moment it becomes a common outreach pattern, the friction arrives fast. Text messages feel more personal and more invasive than email. One bad message lands worse than ten bad emails.

Use it selectively. Works best as a follow-up to a cold email that went unanswered, not as an opening channel. If you need mobile numbers to complement your cold email list, ScraperCity's mobile finder can surface verified numbers tied to business contacts. But the tactic requires discipline. Personalize or don't send.

The Proof Problem Twitter Keeps Rediscovering

@warikooView on X
Received a cold email this morning for a content role at WebVeda. 2 years of experience. A long list of tools. A certificate for each one. She claimed she could help repurpose my long form content into short form, subtly inserting WebVeda in it. I asked her to show me something she had built. She sent across 3 links. All dead. I asked again. She sent a word doc with the original email rewritten. :((() AI has made it easier than ever to reach out. AI has made it harder than ever to convince.
215 likes · 26 replies · 38 saves

"AI has made it easier than ever to reach out. AI has made it harder than ever to convince." That's the most accurate one-liner about the current state of cold outreach I've seen this week.

The story is a textbook example of the proof problem. Certificates are not proof. A list of tools is not proof. Even two years of experience is not proof if you can't show the output. Three dead links and a rewritten email is not proof. It's embarrassing, and the candidate probably used AI to write the initial outreach, AI to generate the list of tools, and then had nothing real to back any of it up.

The fix is not complicated. Before you send any cold email, ask yourself: if they reply and ask to see the work, what do I show them? If the answer is unclear, fix that before you send a single email. Your proof needs to be one click away, not buried in a Word doc. See the Killer Cold Email Templates for how to structure your outreach around proof rather than claims.

The Sales Rep Actually Posting Numbers

@Pipeline_papiView on X
Another great Q. My stats so far since joining REDACTED Q4 25 - 140% Q1 26 - 133% Q2 26 - 162% Achieved mostly through cold email as workhorse and strong relationships with AEs that have the ability to find creative ways to push deals forward I do less outright cold calling and more lukewarm calling using DemandBase signals Cold calling is always king but can achieve your goals in other ways now with all the tools we have at our fingertips
57 likes · 6 replies · 19 saves

Three consecutive quarters above quota. Cold email described as the workhorse. Intent signals used to warm up calls before they happen. This is what a functioning modern outbound motion actually looks like. Not a Twitter thread with stock photo results. A rep posting their real numbers.

The shift from cold calling to "lukewarm calling" using intent data like DemandBase signals is the right evolution. You're still making calls. You're just not making them blind. The call success rate goes up when you know the prospect has been researching a relevant topic in the last 30 days. That's not a replacement for cold calling. It's cold calling with better targeting.

The Takeaway This Week

The throughline across the best posts this week is the same: targeting and proof beat volume and tools.

The beard brand guy wins because his list is built on intent. The Gojiberry team wins because they filtered 295,000 sends down from a much larger potential pool and kept sequences short. The AI agent story works because 18,400 companies were analyzed to produce 1,276 sends. Every post with real numbers this week has aggressive filtering behind it.

Meanwhile, the cautionary stories all share the opposite problem. The candidate with dead links had no proof behind her claims. The alleged chargeback situation involves someone with a 0.001% reply rate blaming infrastructure for a copy and targeting failure.

Your list quality and your ability to prove your claims are the two levers that move reply rates. Not the subject line. Not the sending tool. Not whether you use plain text or HTML. Start there, then optimize everything else.
