Using AI Compose to Write Emails Faster

Let AI draft your emails from a short prompt. Available on Pro and Premium plans.

Updated September 3, 2026

Using AI Compose

Kerabie Mail includes an AI writing assistant that drafts full emails from a short description. Powered by Google Gemini.

Plan requirement: AI Compose is available on Pro (50 requests/day) and Premium (unlimited) plans.


How to use it

  1. Open the compose window.
  2. Click the AI button (sparkle icon ✨) in the toolbar.
  3. Describe what you want to write — e.g. "Politely ask the client for an update on the project timeline".
  4. Click Generate.
  5. The AI will draft a full email into the compose body.
  6. Edit as needed and send.

Tips for good results

Instead of... Try...
"Write an email" "Write a professional apology to a client whose order was delayed by a week"
"Email about meeting" "Invite the team to a planning meeting on Friday at 10am, include agenda items: Q3 goals, budget, hiring"
"Follow up" "Follow up with Sarah about the invoice #1042 sent last Tuesday, keep it friendly"

The more specific your prompt, the better the output.


Tone options

After generating, you can ask AI to adjust the tone:

  • More formal — removes contractions, uses professional language
  • More casual — conversational tone, good for internal emails
  • Shorter — concise version of the same message
  • Longer — expands with more detail
