We have all had those horrific moments (perhaps some of us more often than others) when we find we just sent an important email with an embarrassing typo, or perhaps a promised attachment is missing. If you have quick reflexes and use Gmail, you may be able to save these messages in time to avoid embarrassment.

But you don’t really need to be quick reflexes like Gmail does allows you to set your “Undo Submit” cooling-off period Be 30 seconds long – plenty of time to spot and fix your mistakes. You may not often need a 30 second delay, but when you do you’ll be really glad you did.

To Expand Your Gmail Undo Send Window

Open your inbox and tap the settings gear. When your quick settings window appears, select Show all settings. On the General tab, you will find the Undo Send section, where you can open the drop-down list and choose a period of notice between 5 and 30 seconds. Scroll down and tap save Changes Button.

Now when you send messages, the Message Sent pop-up that appears in the lower left corner will remain visible for the time you specify so that you can select the option Cancel easily accessible.

Unfortunately, Outlook doesn’t provide an email undo grace period that is the same as Gmail’s Undo Send feature. You can Call back messages after they have been sent, but this will only work if you and the recipient have Microsoft 365 or Exchange email accounts in the same organization and the recipient hasn’t opened the message, which is quite limited in functionality.

The workaround is too Set up a rule for your outbox that delays message delivery by up to two hours after you click Submit. Emails are saved in your outbox for the time you specify – just in case you change your mind. This of course delays all outgoing emails, including urgent ones. Also, when using this hack, be sure to check your outbox regularly to make sure nothing is stuck there.

If you need a message in Outlook or want to call back, go to your Sent Items folder and double-click the message you want to call back. Tap the Message tab, go to Action> Call back this message, to choose Delete unread copies of this messageand click OK. You can also replace it with a new message.
