Copy any prompt into ChatGPT, Claude, Gemini, or the AI writer inside your email tool, then swap everything in [BRACKETS] for your own details: business name, audience, offer, deadline, and voice. Paste a past email that performed well when a prompt asks about your voice, since examples beat descriptions. Ask for several versions and pick or combine the best parts. Before sending, check every price, date, discount code, and link yourself, because AI will happily invent details it does not know. Keep subscriber names, email addresses, and order data out of public chatbots, and use merge tags like [FIRST NAME] instead of real customer information.
Subject lines and openers
Generate subject lines to test
Before sending any campaign, so you have options to test.
Write 20 email subject lines for an email from [BUSINESS NAME] about [EMAIL TOPIC OR OFFER] to [AUDIENCE]. Keep each under 50 characters. Mix five styles: curiosity, direct benefit, question, number or list, and personal. Mark the three you think are strongest for an A/B test and avoid spam trigger words like FREE in all caps or excessive punctuation.
Write preview text
When your preview text is blank or just repeats the first line.
Here are my subject lines: [PASTE SUBJECT LINES]. For each one, write preview text of 40 to 90 characters that adds new information instead of repeating the subject. The email is about [TOPIC] and the main call to action is [CTA]. Keep the tone [TONE].
Rewrite a weak opening line
When people open your emails but do not read past the first line.
Here is the first paragraph of my email: [PASTE]. Rewrite it five ways so the first sentence earns the second. Options should open with a question, a short story, a surprising detail, a direct promise, and a reader problem. Keep each under 40 words and match the voice of [BUSINESS NAME], which is [DESCRIBE VOICE].
Personalize by segment
When you have a segmented list but no time to write separate emails.
I am sending one email about [OFFER] to three segments: [SEGMENT 1], [SEGMENT 2], and [SEGMENT 3]. Write a subject line, opening sentence, and call to action for each segment that speaks to what that group cares about most. Keep the rest of the email the same so I only swap these three parts.
Write a plain text style email
When glossy campaigns feel impersonal and you want more replies.
Rewrite this email so it reads like a personal note from [SENDER NAME], the [ROLE] at [BUSINESS NAME], instead of a designed newsletter: [PASTE EMAIL]. Use short paragraphs, first person, one link only, and a sign off that invites a reply. Keep the offer and facts exactly the same and keep it under 150 words.
Write a call to action
When readers open and read but do not click.
My email asks readers to [ACTION, E.G. BOOK, BUY, REPLY]. The audience is [AUDIENCE] and the main hesitation is [HESITATION]. Write 10 button labels under 5 words and 5 one sentence lines to sit above the button that remove the hesitation. Avoid generic labels like Click Here or Submit.
Campaign emails
Write a promotional email
For sales, discounts, and limited time offers.
Write a promotional email for [BUSINESS NAME] announcing [OFFER] for [AUDIENCE]. The offer ends on [END DATE]. Include a subject line, preview text, a short opening, three bullet benefits, a clear call to action button label, and a P.S. that restates the deadline. Keep it under 200 words and avoid exaggerated claims.
Announce a new product or service
When launching something new to your existing list.
Write an email announcing [NEW PRODUCT OR SERVICE] from [BUSINESS NAME]. Here is what it is: [DESCRIPTION]. Who it is for: [AUDIENCE]. Price: [PRICE]. Explain why we made it, what problem it solves, and how to get it. Give two versions: one short (under 120 words) and one longer story version (under 300 words).
Write a newsletter
For regular weekly or monthly emails that keep your list warm.
Write a newsletter email for [BUSINESS NAME] to [AUDIENCE]. Include: one useful tip about [TOPIC], one short update ([UPDATE]), one featured product or service ([FEATURE]), and one question that invites replies. Keep it under 350 words, friendly, and skimmable with short headers.
Write a last chance email
On the final day of a sale or enrollment window.
Write a last chance email for [OFFER] that ends [DEADLINE]. Our earlier emails said: [SUMMARY OF EARLIER EMAILS]. Make it short (under 120 words), restate the offer plainly, answer one likely objection ([OBJECTION]), and use honest urgency only. Give three subject line options.
Write an event invitation
For workshops, open houses, webinars, and in store events.
Write an email inviting [AUDIENCE] to [EVENT NAME] on [DATE AND TIME] at [LOCATION OR LINK]. Explain what they will get from attending, who is hosting, and how to RSVP by [RSVP DATE]. Then write a short reminder email for the day before and a thank you email for after the event with [FOLLOW UP OFFER OR RESOURCE].
Turn a blog post into an email
When you publish content and want your list to see it.
Here is a blog post: [PASTE POST]. Turn it into an email for my list that gives the main takeaway in under 200 words and links to the full post with [LINK TEXT]. Keep my voice, cut anything that is filler, and write three subject lines that make the reader curious about the post.
Write a customer story email
When social proof would sell better than a discount.
Turn this customer story into an email: [STORY: WHO THEY ARE, THE PROBLEM, WHAT THEY BOUGHT OR DID, THE RESULT]. Tell it in under 250 words with a clear beginning, middle, and end, then link it to [OFFER OR PRODUCT] with a soft call to action. Remind me to get the customer's permission before sending.
Write a price increase notice
When you need to raise prices without losing goodwill.
Write an email telling customers of [BUSINESS NAME] that prices for [PRODUCT OR SERVICE] will change from [OLD PRICE] to [NEW PRICE] on [DATE]. Explain the reason honestly ([REASON]), mention what is not changing, and give loyal customers [GRACE PERIOD OR OFFER] if we have one. Keep it calm, respectful, and under 180 words.
Automated sequences
Write a welcome sequence
When setting up the first automation in any email tool.
Write a 4 email welcome sequence for new subscribers to [BUSINESS NAME], who signed up through [SIGNUP SOURCE] to get [LEAD MAGNET OR DISCOUNT]. Email 1 delivers it. Email 2 tells our story. Email 3 shares the most helpful tip or best seller ([TIP OR PRODUCT]). Email 4 makes an offer: [OFFER]. Include send timing, subject lines, and body copy under 180 words each.
Write an abandoned cart series
For online stores losing sales at checkout.
Write a 3 email abandoned cart series for [STORE NAME], which sells [PRODUCTS]. Email 1 sends after [HOURS] hours as a friendly reminder.

Write a post purchase sequence
To reduce refunds and get repeat buyers and reviews.
Write a post purchase sequence for customers who bought [PRODUCT OR SERVICE] from [BUSINESS NAME]. Email 1: thank you and what to expect next. Email 2: how to get the most out of it ([TIPS]). Email 3: ask for a review at [REVIEW LINK]. Email 4: suggest [RELATED PRODUCT]. Give timing and subject lines for each.
Write a re-engagement sequence
Before cleaning your list so you keep the people who still care.
Write a 3 email re-engagement series for subscribers who have not opened an email from [BUSINESS NAME] in [TIME PERIOD]. Email 1 asks if they still want to hear from us. Email 2 shares our best content or offer: [BEST CONTENT OR OFFER]. Email 3 says we will remove them unless they click. Keep it friendly and short.
Write a lead nurture sequence
For service businesses with a longer buying decision.
I sell [SERVICE] to [AUDIENCE], and people usually take [TIME] to decide. Write a 5 email nurture sequence for leads who requested [LEAD MAGNET]. Cover: their main problem, a common mistake, a short case story ([STORY DETAILS]), answers to objections ([OBJECTIONS]), and an invitation to [BOOK A CALL OR BUY]. Keep each under 200 words.
Write a birthday or anniversary email
For simple automations that build loyalty.
Write a short birthday email and a customer anniversary email for [BUSINESS NAME]. The birthday gift is [GIFT OR OFFER] valid for [DAYS] days. The anniversary marks [NUMBER] year(s) since their first purchase. Keep both under 80 words, warm, and personal, using a [FIRST NAME] merge tag.
Strategy and improvement
Plan an email calendar
At the start of a quarter.
Create a 3 month email calendar for [BUSINESS NAME]. We email [FREQUENCY] to about [LIST SIZE] subscribers. Key dates and launches: [DATES AND LAUNCHES]. Balance helpful content and promotions so no more than one in three emails sells. For each email give the date, topic, goal, and a working subject line.
Diagnose low open or click rates
When results drop and you are not sure why.
My emails get an open rate of about [OPEN RATE] and a click rate of about [CLICK RATE]. Here is a recent email with its subject line: [PASTE EMAIL]. My list came from [LIST SOURCE] and I send [FREQUENCY]. List the most likely reasons for low performance, ranked, and give a specific fix for each that I can test in my next send.
Create a lead magnet idea
When your list is growing too slowly.
My audience is [AUDIENCE] and I sell [PRODUCT OR SERVICE]. Suggest 10 lead magnet ideas that would make them happily give their email, such as checklists, guides, quizzes, or discounts. For the top three, write the title, a one sentence promise, an outline, and the signup form headline.
Write signup form copy
When visitors come to your site but few subscribe.
Write signup form copy for the [LOCATION, E.G. POPUP, FOOTER, CHECKOUT] on [WEBSITE]. Incentive: [INCENTIVE]. Give five versions, each with a headline under 8 words, a supporting line under 20 words, a button label, and a short privacy reassurance line.
Edit an email for clarity
Right before you hit send.
Edit this email to make it clearer and shorter without changing the offer or facts: [PASTE EMAIL]. Cut filler, break up long paragraphs, make the call to action obvious, and check that it reads well on a phone. Show the edited version, then list what you changed and why.
Plan an A/B test
When you want to improve results with evidence, not guesses.
I want to improve [METRIC] for my [EMAIL TYPE]. My list has about [LIST SIZE] subscribers. Suggest five A/B tests ranked by likely impact, explain what to change and keep the same in each, the minimum list size where the result is meaningful, and how to decide the winner. Keep it simple for a non technical owner.
Questions people ask
Can ChatGPT write marketing emails?
Yes. ChatGPT, Claude, and Gemini can all write subject lines, campaigns, and full automated sequences in seconds. The quality depends on the context you give: your audience, offer, deadline, voice, and a sample of a past email that worked. Always edit the draft, check every fact and link, and make sure the offer matches what your store or booking system will actually honor.
What is the best AI prompt for email subject lines?
Ask for many options at once, give a character limit, name the audience and offer, and ask for different styles. For example: 'Write 20 subject lines under 50 characters for a spring sale email to past customers, mixing curiosity, benefit, and question styles.' Then test the best two against each other instead of trusting any single pick.
Will AI written emails land in spam?
AI writing by itself does not send emails to spam. Deliverability depends mostly on your sending setup, list quality, and how people engage. That said, AI drafts sometimes use hype heavy words, all caps, and lots of exclamation marks, which can hurt. Ask for a plain, conversational tone and send to people who actually opted in.
