How to Use AI to Write Better Emails (With Real Examples)
Most people use AI for email wrong. Here's what actually works.
The first time I used AI to help write an email I typed "write me a professional email to my client about a project delay" and got back something that started with "I hope this message finds you well."
I deleted it immediately.
The problem wasn't the tool. It was that I gave it nothing to work with. No context, no relationship history, no sense of what I actually needed the email to accomplish. I asked a vague question and got a vague answer.
Once I figured out how to actually use these tools for email, it changed how I work. Not because AI writes better emails than I do. Because it gets me to a first draft in 30 seconds that I can edit, rather than staring at a blank screen for ten minutes trying to find the right opening line.
Here's what actually works.
The thing most people get wrong
They ask AI to write the email from scratch with almost no information. The output sounds like every other corporate email ever written because that's all it has to go on.
The fix is simple. Give it context before you ask for anything. The more specific the situation, the better the output. Think of it like briefing a colleague who is smart but knows nothing about your business, your client, or what happened last Tuesday.
Real example 1: The difficult conversation
The situation: A vendor has missed a deadline for the third time. You need to address it directly without blowing up the relationship because you still need them for two more projects this quarter.
Bad prompt: "Write an email to a vendor about missing a deadline."
Good prompt: "I need to email a vendor who has missed a deadline for the third time. I'm frustrated but I still need them for two more projects this quarter so I can't burn the bridge. The tone should be direct and firm but not hostile. I want to make clear this can't keep happening without sounding like I'm threatening them. Keep it under 150 words."
What you get back is actually usable. Not perfect, but a solid draft you spend two minutes editing rather than twenty minutes writing.
Then you can push further. "The second paragraph sounds too passive. Make it clearer that there will be consequences if this happens again, without spelling out what those consequences are." One more round and you have something you'd actually send.
Real example 2: Saying no without closing a door
The situation: Someone you respect has asked you to speak at their event. You don't have time this quarter but you want to stay on their radar for future opportunities.
The prompt: "I need to decline a speaking invitation from someone I want to maintain a good relationship with. I genuinely can't do it this quarter but I'd like to be considered for future events. The email should feel warm and personal, not like a form rejection. Three short paragraphs max."
What to look for in the output: AI tends to over-explain the reason for declining. Real people don't do that. If the draft has a long paragraph justifying why you're busy, cut it to one sentence or remove it entirely. The less you explain, the more confident it reads.
Real example 3: Following up without being annoying
The situation: You sent a proposal two weeks ago. No response. You need to follow up without sounding desperate or passive aggressive.
The prompt: "I sent a proposal two weeks ago and haven't heard back. I need to follow up in a way that feels genuinely helpful rather than pushy. Offer something useful, maybe asking if they have questions or if anything has changed on their end. Keep it to three sentences."
Three sentences is the right length for a follow-up. AI will often give you more. Tell it to cut.
The editing step people skip
Whatever AI gives you, read it out loud before you send it.
If it sounds like something a person would actually say, you're good. If it sounds like it was written by a committee, it needs another pass. The most common fixes: cut the opening pleasantry, shorten the first sentence, and make the ask in the last line more direct.
AI gets you 80% there fast. The other 20% is you reading it with fresh eyes and making it sound like yourself.
A prompt template that works for almost any difficult email
Keep this somewhere accessible and fill in the blanks:
"I need to write an email to [who] about [what]. The context is [brief background]. The tone should be [adjective]. The email needs to accomplish [specific goal]. Keep it under [word count or paragraph count]."
That structure alone will get you better first drafts than most people produce after three rewrites.
Email is where most professionals spend a significant chunk of their day and where AI can save the most time with the least learning curve. You don't need to understand anything about how these tools work to get value from them here. You just need to give them enough context to be useful.
Start with one email you've been putting off. Use the template above. See what comes back.
