How To Extend Time Limit Of Gmail’s Undo Send Feature

With Google’s Undo Send feature, Gmail users can recall a sent email within a stipulated time. This feature has a time limit of five seconds for users to recall sent emails, however, you can adjust the time limit to recall the emails.
If you want to use the Undo Send feature on Gmail for a longer period than what is available by default, then you need to follow the steps below.
Step 1: Log in to your Gmail account and go to Settings at the top right corner.
Step 2: Click on “See all settings” to have access to more settings options.
Step 3: Navigate to the “General” tab to find the Undo send option. Tap on the Undo Send feature and choose a Send cancellation period. As mentioned above, you will get four options after the update – 5, 10, 20, and 30 seconds.
Step 4: After clicking on the desired option, you just have to scroll to the bottom and click on Save.
Now you can undo that email in ample time before the “error” you noticed a few seconds after hitting send gets sent.
