How to write emails that sell (and don't end up in the trash)

Updated guide 2026 · 5 min read

Most commercial emails fail for the same reason: they were written thinking about the company, not about the person receiving them. Your customer didn't wake up thinking about your promotion. They're busy. And they decide in two seconds whether to read you or delete you.

Here's the structure that does work, part by part.

The subject: your only chance

If the subject fails, nothing else matters. The email never gets opened.

What doesn't work

❌ "UNMISSABLE PROMO!!! 50% OFF TODAY ONLY"

Capital letters, repeated punctuation, and fake urgency. This triggers spam filters and breeds distrust.

What does work

✅ "Your usual order, this week at 20% off"

Concrete, personal, no shouting. A good subject is short (under 50 characters), specific, and honest about what's inside.

Fact: subjects generated with artificial intelligence increase open rates by up to 26%, because they test angles you wouldn't consider on your own.

The first line: don't waste it

Many emails start with "We hope you're doing well". That says nothing and takes up the most valuable space.

Your first line should do one of these three things: name a real problem, give concrete news, or ask a question that matters to them.

❌ "Dear customer, we hope this message finds you well. We are pleased to inform you that..."

✅ "You're running out of stock right when you sell the most. I have a proposal for you."

The body: one email, one idea

The classic mistake is cramming five promotions, three updates, and a birthday greeting into the same email. The result is that they act on none of them.

Simple rules for the body:

The closing: ask for one thing only

If at the end you give three options (buy, reply, follow us, visit the site), they'll do none. Confusion kills action.

End with a single clear instruction: "Reply to this email and I'll set yours aside" or "Tap here to see the catalog". Direct, specific, easy.

The details that avoid spam

An email can be perfectly written and still not arrive. These elements are mandatory:

A complete example

Subject: Your size is back in stock (6 left)

Hi Ana,

The model you were looking for is back in your size. There are 6 units left and they tend to go fast.

I'll set one aside for you until Friday if you reply to this email.

Camila
Lorena Store · Calle 12 #4-30, San Gil

Short, personal, with a single action and no fluff. That's what an email that sells looks like.
