Write in a panel docked at the bottom of the window, or pop it out into its own tab or window. Keep several drafts open, and never lose what you were writing.

What it does
Write where you work
Docked and ready
New message, Reply, Reply all and Forward open a panel at the bottom of the window.
Several drafts at once
One draft is open and the rest wait as bars along the bottom, never in your way.
Its own tab or window
Pop a draft out into a browser tab, or its own window in the Windows app, to write beside your mail.
Saved as you write
Your draft is kept on our servers as you type, so a closed tab costs you at most a moment.
How it works

Send, or set it aside
Press Send, or Ctrl Enter. Minimise a draft to come back to it, and find unfinished ones in Drafts.
Good to know
The details
- Where
- Docked at the bottom of the window, and full screen on a phone. Open in a new tab pops a draft out: a browser tab on the web, its own window in the Windows app.
- Formatting and spelling
- Bold, italic, strikethrough, lists, quotes and links. Spell check in English and Greek runs on your device, so nothing you type leaves it.
- Attachments
- Up to 25 files in a message, 25 MB each. Where your organisation allows it, a bigger file goes as a download link, up to 2 GB.
- Your defaults
- Settings › Writing sets what R does, whether replies quote the original, where your signature sits and which address new messages start from.
