Email CopywritingWriting to one person

Email is the most personal format in marketing#

An email lands in the same place as messages from a reader's colleagues, family and bank. That proximity is a privilege and a trap. Copy that would be fine on a billboard feels loud and impersonal in an inbox. Copy that reads like a note from a thoughtful person feels at home.

So the first discipline is to imagine one reader. Not 'our audience' or 'the segment', but a single person with a specific reason for being on your list and limited time. Write to them. Everything else in this guide follows from that choice.

One reader, one idea, one action#

Most weak emails try to do too much. A newsletter that announces a product, shares three articles, promotes a webinar and asks for a review is four emails competing for one moment of attention. The reader does none of them.

Pick the single idea the email exists to convey and the single action you want taken. Supporting content is allowed, but it must clearly support. If you have four important things to say, you probably have four emails, or a newsletter with a clearly ranked lead story.

A writing process that works under deadline#

Writing the subject line last is deliberate. Until the body is finished, you do not truly know what the email promises, and a subject written first tends to over-promise. Our guide to email subject lines goes deeper.

Structure: the inverted pyramid, adapted for inboxes#

Readers decide in the first few lines whether to continue. Put the most important point first, then the supporting reasons, then the detail. If the reader stops after two sentences, they should still know what you wanted and why.

• Opening line: the point, or the reason this matters to the reader now. Not 'We hope this email finds you well'.
• Body: two to four short paragraphs or a tight list of reasons. One idea per paragraph.
• Call to action: a specific verb and outcome, such as 'Book your fitting' or 'See the three plans', placed where the argument has earned it.
• Close: a human sign-off and, where useful, a reply invitation. Replies are good for the relationship and for deliverability.

Voice: sound like a person who works there#

Brand voice guides often push email towards corporate polish. Resist it. The emails that perform best usually sound like a knowledgeable person writing to someone they respect: direct, specific, occasionally warm, never breathless. Our guide to brand voice helps define the boundaries.

Specificity beats adjectives#

'High quality' is a claim every competitor makes. 'Stitched with a double seam at the stress points' is a fact the reader can picture. Replace adjectives with concrete details: what it is made of, how long it takes, what it replaces, what happens next. Specifics are more persuasive and more trustworthy.

The same applies to proof. Use evidence you can stand behind: genuine reviews you have permission to quote, demonstrations, clear guarantees. Never invent testimonials, results or scarcity. Apart from the legal risk, readers notice, and trust once lost in email is very hard to rebuild.

Calls to action that get clicked#

A call to action should describe the outcome of clicking, not the click itself. 'Choose your size' tells the reader what happens; 'Shop now' only tells them they will be shopping. Use one primary button. Secondary links are fine for readers who want more, but they should look secondary.

Writing for different moments#

The principles stay constant, but the emphasis shifts with the type of email. A promotional email needs a clear offer and a reason to act now. A nurture email needs to teach something the reader can use even if they never buy. A post-purchase email needs reassurance and practical help, with selling held back. A re-engagement email needs honesty about the gap and an easy choice.

Newsletters deserve a special word. The best ones have a recognisable voice, a consistent structure and an editor's judgement about what to leave out. Readers subscribe to a point of view, not a content feed. If your newsletter could have been assembled by an algorithm from your blog's latest posts, it probably reads that way. Our guide to newsletter strategy develops this.

Finally, write for the language your reader chose. In multilingual markets, a well-written email in the reader's preferred language beats a polished one in a language they read with effort. Translation should be done by someone who writes well in that language, not only by software.

Test what matters#

Test the things that change behaviour: the offer, the angle, the length, the call to action. Testing two near-identical subject lines on a small list tells you little. When you test, measure clicks and conversions rather than opens, and run the test long enough to be meaningful. Our general guide to A/B testing applies here too, and copywriting frameworks offer useful starting structures.

Write the email you would be glad to receive from a company you already like.
