Undo send
After you press Send, a message waits before it leaves. You have thirty seconds by default to take it back, or you can send it at once if you are sure.

What it does
A moment to be sure
Take it back
Choose Undo in the notice and the message reopens as a draft, ready to edit.
A visible countdown
The notice counts down the seconds and names who the message is going to.
Or send it now
Send now skips the wait, so a message you are certain about is never held up.
Set your own wait
Choose Off, 5, 10, 20 or 30 seconds in Settings › Writing.
How it works
Send, then think twice
- 1
Press Send
The message waits instead of leaving. A notice at the bottom of the screen counts down.
- 2
Undo, or send now
Choose Undo to take the message back, or Send now to skip the wait.
- 3
Or do nothing
When the countdown ends, the message goes. Until then it also shows in Scheduled, with Send now and Undo.
Good to know
The details
- Who can use it
- Everyone. The wait is a personal setting, so each person chooses their own.
- Where
- Settings › Writing › Undo send. With Off, messages leave at once.
- Too late
- If the message has already gone, DMU Mail tells you so.
- Nothing changes early
- Assigning the conversation to you and Close after sending wait until the message has gone. An undone send changes nothing.
- Its own window
- A message written in its own window closes on Send, and its notice, with Undo, shows in the main window.
