You can use AI to rewrite an email without starting from a blank page. Give it your draft, explain the relationship with the recipient, and identify the facts that must stay unchanged. The goal is a clearer message that still says what you intend.
This guide uses fictional emails and editorial rewrites created for illustration. The examples show what to look for when reviewing a draft; they are not results from testing a particular AI product. For the basics of writing a request, start with our AI prompting guide.
In This Guide
- A reusable rewriting prompt
- Turn a blunt request into a polite reminder
- Shorten an email without losing the action
- Keep uncertainty and commitments intact
- Check the final draft before sending
Start With a Reusable Rewriting Prompt
Specify the audience, purpose, tone, and length. Clear instructions are a recurring recommendation in Anthropic’s prompt guidance. Replace vague requests such as “make it professional” with the actual result you need.
Rewrite the email below for [recipient and relationship]. My goal is [the action or information I want to communicate]. Use a [calm, friendly, or direct] tone and keep it under [word limit] words.
Preserve names, dates, amounts, deadlines, and uncertainty. Do not add promises, explanations, apologies, or attachments that are not in my draft. If a missing detail would change the meaning, ask me first. Return a subject line and the revised body.
Draft:
[Paste the email.]
Share only the context needed for the rewrite. Use placeholders for private names or account details when the assistant does not need them. Restore the correct information in the final draft after reviewing it.
Example 1: Make a Reminder Polite and Specific
Before:
Hi Jordan, I still do not have your comments. Send them by 10 October 2026 so I can finish the proposal. Please confirm today that you can meet that date. Thanks, Alex.
Request: Make this courteous and direct. Preserve both the feedback deadline and the request for confirmation today. Do not suggest that the deadline is optional.
Edited example:
Subject: Proposal comments due 10 October
Hi Jordan,
Could you please send your comments by 10 October 2026 so I can finish the proposal? Please confirm today whether you can meet that deadline.
Thank you,
Alex
The revised version removes the accusatory opening while keeping the two requested actions. “Whenever you have time” would sound softer but change the deadline. A good review checks the request as well as the tone.
Example 2: Shorten the Message, Keep the Action
Before:
Hi Priya, I wanted to get in touch because we have been thinking about the next meeting and there are two times we can offer. We can meet on 12 October 2026 at either 10:00 or 14:00, both London time. Could you let me know which works for you by 9 October 2026? Thanks, Sam.
Request: Remove filler and keep the body under 50 words. Preserve the meeting date, both time options, the time zone, and the reply deadline.
Edited example:
Subject: Choose a meeting time for 12 October
Hi Priya,
Would 10:00 or 14:00 London time on 12 October 2026 work for our meeting? Please let me know your preference by 9 October 2026.
Thanks,
Sam
The shorter version still tells the recipient what to choose and when to reply. Check time zones explicitly when a message involves people in different locations.
Keep Uncertainty and Commitments Intact
“We may finish by Thursday” does not mean “We will deliver on Thursday.” Similarly, “I will check whether a refund is possible” does not authorize a refund. Read the revised draft for stronger promises, new reasons, or responsibilities that were not in the original.
Compare the original and revised emails. List any changed date, amount, request, condition, or commitment. Then revise the email to remove unsupported additions while keeping the clearer wording.
If the style still feels wrong, provide a short sample of your preferred writing and explain what to copy, such as sentence length or level of formality. Google’s prompt design guidance discusses using examples and explicit output requirements.
Check the Final Draft Before Sending
Confirm the recipient, subject, dates, time zones, and requested action. Replace placeholders, verify any attachment is actually included, and remove claims you cannot support. Read the email aloud once: it should sound like something you would say and leave the recipient knowing what happens next.
For a long email thread, first separate confirmed facts from open questions. Our AI document summary guide shows how to compare a summary with its source. Review the finished reply yourself before sending it.
