I’m pretty sure that most of us don’t know about this awesome feature in Gmail, or even if you knew it here’s a reminder!
‘Gmail undo send feature’ is a great way to stop and delete the emails that you’ve sent across by mistake and were only starting to regret and hate upon yourselves. Don’t worry you have HELP!
Here’s how to:
Click the gear icon on the right side (see image) and select for ‘settings’ from the dropdown.
Select ‘Labs’ from Tabs (see image).
Scroll at the bottom to find ‘Undo Send’ and hit enable:
Step 4 & 5:
Save the changes. Read through the visual 😉
It defaults so that you have 10 seconds to click before the Undo button disappears, but you can adjust that window of opportunity. Go to Settings > General > Undo Send, and select a cancellation period up to 30 seconds.
