How to Write Marketing Emails That Convert

Inboxes are packed, and winning that split second of attention is harder than ever. But getting read isn’t enough. If you know how to write marketing emails that connect fast, you can turn a quick glance into real action: a site visit, a sale, or a qualified lead that moves your business forward.

At Madwise, we focus on digital actions that bring measurable results. Here are eight practical ways to turn your marketing and sales emails into real conversion powerhouses.

1. Email Copywriting That Feels Personal

Yes, we’re talking about mass emails, but every recipient still wants to feel the message was written for them. That’s where personas make all the difference. When you truly know the person you’re writing to, the tone and message naturally fall into place.

‘Dear Mr. Ana, we’ve prepared a special offer on garden furniture for you…’

When it comes to your recipients, the quality of your contact list matters as much as the email itself. We’ll assume segmentation isn’t new to you. 

But here’s a small extra tip: before you hit ‘send’, make sure your audience is right, and personalisation works as it should. Mrs. Ana from the example above probably won’t be impressed — and she might not even have a garden.

2. How to Write Marketing Emails with Strong Subject Lines

The subject line carries as much weight as a headline in a blog post. If it’s sharp and interesting, people will open your email and keep reading. If it’s not, even the best content stays unseen. 

Numbers attract attention, and curiosity keeps readers hooked. Ask yourself what value you can offer that makes their life easier. Here are eight ways to increase your email conversion rate.

There’s plenty of debate about how much time to spend on a subject line. The most demanding experts say it deserves the same attention as the entire email. 

Two hours on one line might sound excessive, but the message is simple: if no one opens your email, all the work behind it goes to waste.

3. Get to the Point Before You Lose the Reader

‘The days are getting longer, the sun feels warmer, and maybe it’s time to treat yourself to a relaxing afternoon…’

Still with us? 

That was the opening of an email promoting garden furniture. If addressing Mrs. Anna as Mr. Anna didn’t already annoy her, this vague introduction certainly did. 

It says nothing, promises nothing, and gives no reason to keep reading. Many marketers think they need a soft, chatty start to warm up the reader before getting to the point. In reality, they just lose attention.

Say what your email is about — right away.

4. Forget the Jargon, Talk Like a Human

Polite and respectful communication is a must — but it shouldn’t turn into corporate self-praise. No one wants to read phrases like ‘our information solutions ensure efficiency and structure across employee workflows.’

• Does your solution save a department head five hours a week? Say it.
• Do structured documents save every employee two more hours? Say it.
• Can you back it up with data? Do it.

Especially in a world full of complex products and big claims, people value when email copywriting explains things simply: what you offer and how it benefits them.

5. Explain What to Expect — and Deliver It

This tip builds on the previous ones but deserves its own space. When your subject line and opening promise something, make sure the reader actually gets it. 

You don’t want Mrs. Anna (yes, she’s persistent) clicking ‘I want the garden set’ and landing on a page full of kitchen appliances.

Landing pages work when they deliver exactly what was promised and meet the reader’s expectations, whether it’s a rattan sofa or a quick guide to changing a lightbulb.

Great copy brings people to your landing page — automation keeps them coming back. Discover how to build that system in our article on Email Marketing & Automation.

6. Tell the Reader What to Do

The reader opened your email and actually read it. You’ve done a lot already, but don’t stop now. A good email says clearly what the reader should do next if they want what you’re offering. The reader has opened your email and read it — a big step already.

Fight the temptation to add every nice-looking link. Define one clear call to action that leads them where you want them to go. When the path is clear and simple, the reader will reward you with a conversion.

7. One Last Read Can Save the Email

If your marketing email is about to land in 3,000 inboxes, it’s worth having someone else read it first and share honest feedback.

But let’s be real, sometimes you don’t have that option. 

Step away for a moment. Grab a coffee, take a short walk, clear your head. Then come back and read it again. Does the email say what you actually mean? Does the reader know what to do next? If not, fix it before you hit send.

8. Typos Kill Trust Faster Than You Think

Readers expect flawless writing, especially from a brand. Typos, missing commas, and sloppy sentences send a clear message: you didn’t take the time to care. Mrs. Anna took a moment to read your email, the least you can do is make it worth her time.

If your message looks rushed, why would anyone trust you with their business? You wouldn’t either.

How to Write Emails That Win Attention

Write with a real person in mind. Make it clear from the subject line what the email is about, then explain simply what value you bring and what you want the reader to do next. That’s how to write emails that feel personal and get results.

Make sure your message reaches the right person in the right way. Following these tips will give you a clear edge in crowded inboxes — and they work just as well in everyday communication. 

Your boss will appreciate it, and your colleagues might even smile more often.
