Most people fail at cold email because they write emails, not conversations. The goal isn't to sound professional. It's to sound human. Ask yourself: Would I reply to this email if it landed in MY inbox? If the answer's no, start over.

Everyone still obsesses over email personalization in 2025. But most people don't even fix the real problem: RELEVANCE. If your offer doesn’t solve an urgent, expensive, or annoying problem for your prospects, It doesn’t matter how personalized your emails are. Focus on being relevant first. The rest is just optimization.

Most cold emails fail because they sound like ads. Great cold emails feel like a 1-on-1 conversation with an old friend. Here’s the litmus test: If you wouldn’t send it to one person, don’t send it to 1,000.

For the first time in history, you can see if your cold emails will land in the inbox BEFORE sending them. In the last year of running Mailscale, I noticed the biggest outbound marketing challenge is deliverability. Google & Outlook really don't like spam. As a result, most cold emailers send with flagged domains without even realizing it. We've worked tirelessly to solve this with the world's first autonomous deliverability agent. Here's how it works: Every day, I get an automated report via Slack and email. It tells me how healthy my outreach domains are, measured by daily inbox placement tests. Today, we're at 94% which is awesome (see picture) But I also noticed a problem. 14 domains are at risk (below 90% deliverability) This could be a sign of scaling too quickly and Google/Outlook flagging my copy. For the first time, I now have full visibility into my performance. And I’m getting better results, too! Because as soon as a domain becomes unhealthy, it will stop sending cold emails, and will go into a recovery warmup pool until it's healthy. This means I'm only sending from healthy domains instead of wasting my leads. I know all of this is pretty nerdy. But it makes the difference between massively succeeding and barely getting replies in 2025. You either adapt and learn to play or you're out of the game landing in spam without even realizing it. Super excited to roll this out for customers with Mailscale inboxes in 2-4 weeks for beta access. If you're interested, comment "Waitlist" below and I'll send you a private link in the coming days.

Wow… I just saw a statistic that 47% of outreach emails land in spam now. Is this the end of cold email? First of all, you need to understand why this is happening. Why do outreach domains burn often within days? The reason is simple. Even if you do everything right, some prospects will always click the little button that says “Report spam.” Google and Outlook see this. And that’s how domain reputation regularly tanks. The good news is that you can easily recover it. You just need to stop cold emailing from affected domains and send more warm-up emails for a few days. But how do you know which domains are unhealthy? The current state of cold email is confusion and lack of transparency. So we’re planning to roll out a feature inside of Mailscale that will solve this. We’ve created a fully autonomous deliverability agent. It conducts daily inbox placement tests. As a result, we have full clarity on where our emails land in real time. But here’s the magical part: The agent recovers unhealthy domains automatically within 5–7 days. As a result, we only send from healthy domains and increase replies by 2x in our tests. Excited to roll this out! Gonna share more about how we’ve built it here on X.

@Promise_Xvi Thanks

@yassin_baum Very true

Most cold emails fail for one reason: They scream I want something from you. Here’s the rule: Write every email as if you *don’t* need the deal. When you remove neediness, you write like a peer, not a beggar. And peers get replies.

@mejunaidraza Yes it can

@yassin_baum That's a great approach. Do you believe sending emails on the publically given emails (e.g. info@yourdomain.com) can also bring business?

@Coldemailadams Exactly

@yassin_baum Instead of cold Make it warm

@IronRedSandHive Dangerous trap, also in dating

@yassin_baum Why does sounding needy feel like a trap to me?

@Robin_ecomm True haha

@yassin_baum funny how the second you stop sounding desperate, people actually start paying attention

Grok 4 is going to revolutionize cold email in 2025. Here's how to use Grok to research the hidden pain points of your ideal clients and MIRROR them in your copy:

@cbwritescopy That's a wrap. Most people use AI to write generic copy. But if you use Grok to research and think like your ICP, you'll write copy that actually gets responses. This is how you win now.

@cbwritescopy Then add those with one click to a sending tool like Instantly/Smartlead. Get leads from Apollo & Findylead or local leads from D7 Leadfinder. Add your cold email copy and start blasting.
