Talking point of view
You can turn on "Conversation View" if you want to keep all of the emails in a thread together.
Go to Settings > Conversation View > Conversation view on: to do this.
3. Undo send
Since 2015,
gmail sign up users have had up to 30 seconds after clicking Send to take back a message they sent by mistake.
When you send a message through Gmail, a pop-up message will show up.
You can get your email back by clicking "Undo." Make sure not to click "View message," click away from the message, or wait longer than the allotted time.
To change how long you have to cancel a message, go to Settings, scroll down to Undo Send, and use the drop-down menu to choose how long you have.
