Most people spend between one and three hours a day writing emails.
AI can cut that time significantly — not by writing every email for you, but by handling the parts that take the longest: starting, structuring, and finding the right words.
This guide covers exactly how to use AI to write emails faster, with practical examples you can use today.
Which AI Tool Should You Use for Emails
Any of the main AI tools work well for email writing. ChatGPT, Claude, and Gemini all handle email tasks reliably.
If you use Gmail, Gemini is built directly into your inbox and is the most convenient option. If you use Outlook, Microsoft Copilot is integrated natively. If you prefer a separate tool you can use anywhere, ChatGPT or Claude are both strong choices.
Grammarly is also worth installing as a browser extension — it polishes emails as you type across any platform.
The Basics — How to Prompt AI for an Email
The key to getting a good email from AI is giving it enough context. A vague prompt produces a vague email.
A good email prompt includes four things:
Who you are writing to — a client, a colleague, a supplier, a stranger
What the email needs to do — follow up, decline, request, apologise, confirm
The tone you want — formal, friendly, direct, warm
Any important details — names, deadlines, specific context
Example prompt:
“Write a short, professional email to a client called Sarah following up on a proposal I sent last week. Keep it friendly but to the point. Ask if she has any questions and whether she is ready to move forward.”
That level of detail gets you an email that is close to ready in one go.
10 Emails You Can Write Faster With AI
1. Following up on a proposal or quote
Following up is uncomfortable and easy to put off. AI removes the awkwardness by drafting a polite, direct message you just need to personalise.
Prompt: “Write a follow-up email to a potential client who has not responded to my quote for [service]. Keep it brief, friendly, and end with a clear question.”
2. Declining a request politely
Saying no professionally without burning a relationship is one of the hardest emails to write. AI is surprisingly good at it.
Prompt: “Write a polite email declining an invitation to speak at an event. Keep it warm and leave the door open for future opportunities.”
3. Asking for a review or testimonial
Most businesses know they should ask for reviews but never get around to it. AI makes the email easy.
Prompt: “Write a short, friendly email asking a happy customer to leave a Google review. Keep it casual and make it easy for them to say yes.”
4. Chasing a late payment
One of the most difficult emails to write. AI keeps it professional and firm without being aggressive.
Prompt: “Write an email politely chasing a client for an overdue invoice. The payment was due 14 days ago. Keep the tone professional and include a clear call to action.”
5. Introducing yourself to a new contact
Cold emails are notoriously hard to write well. AI can produce a clear, warm introduction that does not sound like a template.
Prompt: “Write a brief introduction email to a potential business partner I met at a conference last week. Mention that we discussed collaborating on content and suggest a short call.”
6. Responding to a complaint
Getting the tone right on a complaint response is critical. Too defensive and it escalates. Too apologetic and you take unnecessary blame.
Prompt: “Write a professional response to a customer complaint about a delayed delivery. Acknowledge the issue, apologise sincerely, and explain what we are doing to resolve it.”
7. Weekly team update
If you send the same type of update every week, AI can write the structure and you just fill in the specifics.
Prompt: “Write a short weekly team update email with sections for: what we completed this week, what is planned for next week, and any blockers. Keep it brief and professional.”
8. Cold outreach to a potential client
Prompt: “Write a concise cold email introducing my [type of business] to a potential client in the [industry] sector. Focus on a specific problem we solve and end with a soft call to action — a quick call or reply.”
9. Thank you after a meeting
A follow-up thank you email after a meeting keeps the relationship warm and confirms next steps in writing.
Prompt: “Write a brief thank you email after a productive first meeting with a new client. Summarise the two main things we agreed to do next and express enthusiasm for working together.”
10. Saying no to a discount request
Prompt: “Write a professional but friendly email declining a client’s request for a discount. Acknowledge their request, hold the price, and reinforce the value of what we offer.”
How to Make AI Emails Sound Like You
Out-of-the-box AI emails can sometimes feel generic. A few adjustments fix this quickly.
Tell it your style. Add a line to your prompt like “write in a conversational, friendly tone” or “keep it short and direct, no filler phrases.”
Give it examples. Paste in a previous email you wrote and say “match this tone and style.”
Edit the opening line. AI often opens with a generic sentence. Replace it with something more natural before you send.
Remove corporate phrases. Words like “as per my last email”, “going forward”, and “please do not hesitate” are AI tells. Delete them.
Save Your Best Prompts
Once you find a prompt that produces a great email for a recurring situation — following up on a proposal, chasing invoices, responding to enquiries — save it.
Keep a simple document with your ten most-used email prompts. Over time this becomes a personal email toolkit that saves you significant time every week.
A Faster Email Workflow
A practical daily workflow using AI for email:
Start your morning by identifying the emails you are dreading or have been putting off. Use AI to draft those first — it removes the mental block of starting. Then review, personalise, and send.
For routine emails you send regularly, build a prompt library and use it directly. For sensitive or high-stakes emails, use AI for the first draft and spend your time on careful editing rather than starting from a blank page.
Conclusion
AI does not replace the judgment, relationship knowledge, or nuance you bring to email. What it does is remove the blank page problem and handle the mechanical work of structuring and phrasing.
The result is that the emails you were putting off get written, the routine emails get done faster, and you spend your time on the parts that actually require you.
