The short answer
An email that sells talks to one person, about one of their problems, and makes a clear offer with one step to take. The structure that has worked in direct mail for a hundred years hasn’t changed: a subject line that promises, an opening that hits the problem, the solution with proof, the offer with a reason to decide now, one button, and a P.S. that repeats the most important thing.
Before you write: who, what, why now
Most sales emails fail before the first word. Not because of the style: because it isn’t clear who they’re for or what they ask. Before you open the editor, answer three questions in writing:
- Who am I writing to? Not “customers”: one person. “The mum who buys bread on Saturday mornings.”
- What do I want them to do? One thing: book, buy that product, reply.
- Why should they do it now? A real reason: genuinely limited places, a season, a deadline, a price that’s about to change.
If you can’t answer the third, your email will be read, liked… and put off. Forever.
The structure of an email that sells
- Subject line: a clear promise or a question that stings (more in how to write subject lines).
- Opening: go straight to the reader’s problem or desire. No “I hope this finds you well”.
- The why: your solution and why it works. Facts, not adjectives: “48-hour proving” beats “delicious”.
- The proof: a real review, a real number, a photo. Never invented: it gets found out, and it costs you dearly.
- The offer: what they get, what it costs, what happens next. As clear as a receipt.
- The reason to act now: a deadline or a limit, as long as it’s real.
- One button: one call to action, with a verb. “Book your table”, not “Click here”.
- The P.S.: many people read the subject, the first line and the P.S. Put the offer there in one sentence.
Write the way you talk at the counter
An email isn’t a brochure. It lands in the same inbox as messages from their mum and their accountant. Write the way you’d talk to them at the counter:
- short sentences, one idea per sentence;
- “you”, not “dear customer”;
- plain words: “price”, not “pricing proposition”;
- bold only for the sentence that matters;
- a real name in the signature, and a way to reply.
If a sentence doesn’t help sell or help understanding, cut it. The email nearly always gets better.
A complete example
A bakery that wants to fill its Christmas cake orders could write something like this (with its own real numbers, not these):
- Subject: The Christmas cake that always sells out by the 20th
- Opening: “Last year, a week before Christmas, we had to say no to a lot of you. This year we want to say it to as few people as possible.”
- The why: “Fruit soaked for a week, fed with brandy, baked in small batches. We make 30 a day, not one more.”
- The proof: a real customer review, with their name if they’ve given permission.
- The offer: “Order now and collect any day up to the 24th. Pay when you collect.”
- The deadline: “Orders close when the oven is full.”
- The button: “Order your Christmas cake”
- P.S.: “Want two? Order them together: the second is the one that runs out first.”
Mistakes that lose sales
- Talking about yourself (“we’re market leaders”, “our passion”) instead of the reader.
- Three offers in one email. People with too many choices don’t choose.
- Fake urgency. Customers notice by the second “last day”.
- A hidden price. If they have to hunt for it, they leave.
- Sending once and disappearing. Someone who doesn’t buy today may buy after the second or third email: plan a follow-up.

Frequently asked questions
How long should a sales email be?
As long as it needs to be, and not a line longer. A reminder fits in 50 words; a new, expensive product may need 300. What matters is that every sentence moves towards the button.
Images or plain text?
Emails that look written by a person often work better than ones that look like a flyer. Use images to show the product, but keep the message in the text: many email apps block images and filters can’t read them.
Should I add a P.S. to an email?
Yes: many people look at the subject, the first line and the end. The P.S. is the right place to repeat the offer or the deadline.
How many times can I send the same offer?
Two or three emails about the same offer, from different angles, are normal: people who missed the first may read the second. Leave out anyone who has already bought.
