Email Copywriting Tips: 11 Rules for Emails People Read
Good email copy does one job per email, opens on the reader’s situation instead of yours, says the point in the first two lines, and ends with one clear next step. Write it the way you’d write to one person you know, cut every line that doesn’t move them toward that step, and read it on a phone before you send it.
Below are 11 email copywriting tips for launch emails and newsletters, grouped by the part of the email they fix.
Why do most marketing emails get ignored?
Because they’re written for the sender. The founder wants to share the update, the feature list and the story behind it, all at once. What lands in the inbox is a wall of text with three links and no reason to care in the first line.
The cost shows up slowly. Each email that wastes a reader’s time teaches them to skip the next one. Open rates sink, and the list you spent months building stops responding right when you have something to sell.
Most of this is fixable at the writing stage, before any tool or send-time trick.
What is the most important email copywriting rule?
1. Give every email one job. Decide before you write what the reader should do or believe when they finish: reply, click to the pricing page, read the post, book the call. Everything in the email serves that one job. If you have three things to say, that’s three emails.
2. Write to one reader. Picture a specific person on your list and write to them. “You” should mean someone, not “our valued subscribers”. This single change fixes most of the stiffness in founder emails.
How do you start a marketing email?
3. Make the first line work on its own. The opening line shows in the preview pane on many inboxes, so it’s a second subject line. Start on the reader’s situation or the point of the email, not on “Hi there, I hope you’re well” or “This month we’ve been busy”.
| Opening that delays | Opening that gets to it |
|---|---|
| I hope this email finds you well. | You asked how we write subject lines. Here’s the checklist. |
| We have some exciting news to share! | The export bug you reported is fixed. |
| As you may know, we’ve been working hard on… | If you write landing pages with ChatGPT, this saves you a review pass. |
4. Pair the subject, preview and first line. Treat them as one thought in three parts. The subject earns the open, the preview text adds the detail, and the first line picks up from both. Our guide to email subject lines covers the patterns and the 50-character default.
How should the body of an email be written?
5. Use a framework for the argument. A short sales email fits PAS: name the problem, show what it costs, give the fix. A longer one fits AIDA or before-after-bridge. The framework stops the body from wandering. See all of them in copywriting frameworks.
6. Keep paragraphs to one to three lines. Most email is read on a phone. A five-line paragraph on a laptop is a full screen on a phone. Break at every new idea.
7. Trade adjectives for specifics. “Our powerful new feature” says nothing. “Export your report to PDF in one click” says what changed. Specifics are also what readers remember and forward.
8. Answer the objection before it’s raised. If the email asks for money, say what the reader is worried about and answer it: the price, the time it takes, what happens if it doesn’t fit. Our post on handling objections in copy lists the common ones.
How many links and calls to action should an email have?
9. One call to action, linked once or twice. Every extra link splits the reader’s attention. Name the action in the link text (“See the plans”, “Reply with your question”), not “click here”. If it’s a long email, repeat the same link near the end. More on this in how to write a call to action.
10. End with the next step, not a sign-off speech. The last line before your name should be the action. Skip the paragraph of thanks and “let me know if you have any questions” when the email already asks for one specific thing.
How do you edit an email before sending it?
11. Read it out loud, on a phone. Out loud, you’ll hear the sentences no person would say. On a phone, you’ll see the paragraphs that turn into walls. Then cut: most first drafts lose a third of their words with nothing lost.
A quick pre-send check:
- Can you say the email’s one job in a sentence?
- Does the first line make sense without the subject?
- Is every claim and number true and backed by something you can show?
- Is there exactly one call to action?
- Does it read like you, not like a press release?
Can AI write good marketing emails?
It can write a fast first draft. Give it the one job, the reader, the facts it may use and the call to action, and ask for a short version. Left alone, models open with pleasantries and add a link to everything. Edit the draft against the tips above, and see how to edit AI drafts and making AI writing sound human for the tells to remove.
If you write your emails inside Claude or ChatGPT, Copix adds two tools there. write with the asset email returns the method before the AI drafts: the framework, the subject line formulas and the rules for that email, or a whole sequence (welcome, launch, nurture and others) with the job of each email. review checks the draft, the subject and the preview text in one pass and points to the exact line to fix. It works from your saved brief, so the AI writes from your facts instead of inventing them. Copix Basic is $9 a month. The first plan starts with a 7-day free trial (card at checkout, nothing charged if you cancel before it ends); see the plans or the setup guide.
FAQ
How long should a marketing email be?
As long as its one job needs. A reply request can be three lines; a launch email that sells a paid product often needs more to answer the objections. Cut anything that doesn’t serve the job.
Should marketing emails be plain text or designed?
Plain text, or close to it, reads like a person wrote it and suits founder emails and newsletters. Designed emails suit catalogs and stores with many products. Test both if you’re unsure.
How do you make an email sound less salesy?
Write to one person, state what you’re offering plainly, give the real reason it might help them, and drop the hype words. Honest selling doesn’t sound salesy; hiding the ask does.
How often should you email your list?
Often enough that readers remember who you are, and only when you have something useful to say. A steady weekly email beats a burst of daily emails followed by months of silence.
