How to Write a Cold Email That Actually Gets Replies

I've sent thousands of cold emails. Most of them were bad. I know this because I can compare my old reply rates (around 2%) to my current reply rates (closer to 18%) — and the difference comes down to a handful of principles I learned the hard way.

Cold email still works. But only if you understand why most cold emails fail, and then do the opposite.

Why Most Cold Emails Get Deleted Immediately

Before we talk about what to write, let's talk about what not to do — because it explains everything.

Most cold emails fail for one of three reasons:

They're about the sender, not the recipient. "My name is [Name], I'm the founder of [Company], and we help businesses like yours..." — nobody cares about you. They care about themselves. Lead with something about them.

They're vague. "I'd love to connect and explore potential synergies." What synergies? What do you actually want? Ambiguity reads as a time-waster.

They ask for too much too soon. Asking a stranger for a 45-minute strategy call is a big ask. The first email should ask for something small — a yes/no, a quick reply, a piece of information.

The formula I use now fixes all three of these problems.

The Cold Email Formula That Actually Works

I call it the PACT formula — Problem, Action, Credibility, Tiny Ask.

P — Problem: Open with something specific about them that shows you actually did research. Then identify a specific problem they're likely experiencing.

A — Action: Describe one specific thing you can do to solve that problem. Be concrete, not abstract.

C — Credibility: One sentence of relevant proof. Not a list of achievements — one specific result.

T — Tiny Ask: Ask for something that takes 30 seconds to respond to. Not a call. Not a Zoom. A yes or a no.

Here's an example:

Subject: Your checkout page

Hi Sarah,

I was looking at your digital product store and noticed your checkout flow has 4 steps before payment — most high-converting stores cut it to 2.

I optimized the checkout for a similar store (The Budgeting Nerd) and their conversion rate went from 2.1% to 3.8% in three weeks.

Would it be helpful if I sent a quick Loom showing exactly what I'd change on yours? No obligation — just want to show you what I'm seeing.

—Michael

That email is 74 words. It's about her problem, not my story. It has one specific proof point. And it asks for a "yes to a Loom video," not a 45-minute discovery call.

The Subject Line Problem

The subject line is the email's biggest variable — it determines whether anyone opens it. Bad subject lines sound like marketing. Good subject lines sound like they're from a real person.

What doesn't work:

• "Quick question about your business"
• "Opportunity for [Company Name]"
• "Re: Partnership Idea"

What does work:

• A single specific thing: "Your about page" or "Your January blog post"
• A genuine question: "Is [specific outcome] something you're working on?"
• An observation: "Noticed something on your pricing page"

Short is almost always better. One to four words tend to outperform longer subject lines. The subject line's only job is to get them to open — it doesn't need to explain everything.

Research Before You Write

The single biggest lever for cold email reply rates is personalization — and personalization requires research.

Before I write a cold email, I spend 5 to 10 minutes looking at:

• Their website (what they sell, how they position it, what seems off)
• Their recent content (blog posts, podcast episodes, social posts)
• Their LinkedIn (current role, recent activity)
• Any public press or interviews

I'm looking for one specific thing to open with. Not a generic compliment — a specific observation. "I saw you recently changed your pricing from monthly to annual" is specific. "Your content is great" is noise.

The more specific your opening, the higher your reply rate. Full stop.

Timing and Volume

Reply rates vary significantly by day and time. Based on my own data:

Tuesday, Wednesday, and Thursday mornings (before 10am recipient time) tend to perform best. Monday is bad — people are buried. Friday afternoon is bad — people are checked out.

On volume: don't blast 500 emails at once. Send 10 to 20 per day, personalize each one, and track what's working. A batch of 20 personalized emails will get more replies than 200 templated ones. Every time.

The Follow-Up Sequence

Most replies don't come from the first email. They come from the second or third.

My follow-up sequence:

Day 1: Send the original email. Day 4: One-sentence bump. "Did this land in the right place?" Day 9: A different angle. Share a quick insight, a piece of relevant content, or a new question. Not just "following up." Day 14: One last touch. "I'll leave this with you — happy to chat if the timing's ever right."

Four total touches over two weeks. After that, I stop. Pestering people after four attempts damages your sender reputation and your brand.

What to Do When They Reply "Not Interested"

First: reply and thank them. A gracious response to a rejection keeps the door open for the future.

Second: ask if you can check back in three or six months. About 30% of people say yes. Situations change. Business needs change. That contact you couldn't help in January might be perfect for your product in July.

Third: don't take it personally. A "not interested" reply is just data. It might mean your offer isn't a fit, your timing is off, or your message missed the mark. Adjust and move on.

Cold Email for Selling vs. Cold Email for Partnerships

The formula above is primarily for selling. But cold email is equally powerful for building partnerships — finding newsletter writers to cross-promote with, connecting with other creators for collaboration, or reaching out to podcast hosts for guest spots.

For partnership cold emails, the same principles apply, but the "tiny ask" is different. Instead of "want me to send a Loom?" it's "would you be open to a quick 10-minute call to see if there's a fit?" — because partnerships inherently require more trust-building before they happen.

The Tool Stack I Use

For sending and tracking, I use simple tools: a Gmail account with a good reputation, a mail merge tool for light personalization at scale, and a spreadsheet to track who I've contacted, when, and what happened.

When I was building my own online business, I used cold outreach alongside the organic channels built into MadeThis.com. MadeThis has outbound tools baked in for reaching potential customers — useful if you want automation behind your outreach without managing a separate cold email stack.

Start Small and Iterate

If you've never sent cold emails before, start small. Write 10 emails this week — fully personalized, following the PACT formula. Track your open rates and reply rates. See what subject lines performed best. Refine one thing at a time.

Cold email is a skill, not a template. The founders who get consistent replies have usually sent hundreds of emails and paid careful attention to what worked. Start the reps now — because every bad email is one step closer to writing a great one.
