Did I just send that message to Sam W.? Ouch...
It may not be too late yet. Gmail can hold back delivering emails for some seconds after you have clicked Send. You can "unsend" an email and recover from false recipients, spelling mistakes and maybe forgotten attachments.
Unsend an Email with Gmail
To take back an email shortly after you have sent it in Gmail:
- Make sure Undo Send is enabled (see below).
- After having sent an email in Gmail:
- Click Cancel immediately,
- click Undo when it appears or
- press z.
- Make any desired changes to the message, then send it again.
You have at least 5 seconds to unsend the email. To increase the time before the email gets delivered:
- Go to Settings in Gmail.
- Pick the desired time to undo message delivery under Undo Send: Send cancellation period: __ seconds.
- Click Save Changes.
While offline, you can avoid having emails sent — and unsend them — for even longer.
Enable Undo Send in Gmail
To have Gmail hold back delivery of sent messages for a few seconds so you can take them back:
- Follow the Settings link in Gmail.
- Go to the Labs tab.
- Make sure Enable is selected for Undo Send.
- Click Save Changes.
