How to Use AI to Write Emails (Fast & Professional)
Learn how to use AI to draft, rewrite, and reply to emails in seconds. We compare the best AI email assistants.
TL;DR
If you spend more than 10 minutes a day writing emails, AI can cut that in half. ChatGPT is great for general drafting, but if you want something built directly into your inbox, Grammarly or native workspace AI (like Google Workspace or Copilot) is the way to go.
Top Pick: Grammarly
Grammarly isn’t just a spellchecker anymore. Its generative AI understands your tone and helps you draft replies directly in Gmail or Outlook.
- Best for: Seamless inbox integration
- Price: Free tier available ($12/mo for Premium)
- Why we love it: You don’t have to copy-paste between tabs.
Step-by-Step Guide: Drafting an Email with ChatGPT
If you want the most control over the output, using a chatbot like ChatGPT or Claude is the best approach.
Step 1: Provide Context
Don’t just say “write an email to my boss.” Tell the AI:
- Who you are emailing (Boss, client, team)
- What the goal is (Ask for time off, pitch an idea)
- What tone to use (Professional, friendly, urgent)
Prompt Example: “Write an email to my manager asking for next Friday off for a family event. Keep the tone professional but warm. Mention that my projects are on track.”
Step 2: Refine the Output
AI rarely gets it perfect on the first try. Ask it to adjust:
- “Make it shorter.”
- “Sound more confident.”
- “Add a bulleted list of my current projects.”
Step 3: Review and Send
Never send an AI-generated email without reading it first. Check for strange phrasing, overly formal language (AI loves saying “I hope this email finds you well”), or factual errors.
