How to recall an email in Gmail 

Author

As Chief Information Security Officer at CloudTech24, I lead security strategy, governance and operational delivery. I help our clients’ executive teams make informed decisions about cyber risk. My role involves understanding how a customer’s business actually works, where the real risks sit, and what it takes to reduce them in a way that lasts, using existing capabilities wherever possible.

My background spans hands-on technical delivery and board-level advisory to clients across fintech, financial services, legal and other regulated industries. I also own our ISO 27001 programme and the ISMS behind it. As AI moves into everyday business use, I also ensure that our usage of AI aligns to best practise through governance and policy, and advise leadership and customers on safe adoption, aligning toward emerging standards such as ISO 42001 and the EU AI Act.

Outside of work, I’m a proud dad to two brilliant daughters and a lifelong LEGO enthusiast – if we’ve had a video call, chances are you’ve seen a few of my builds in the background. I’m also a passionate gamer and PC builder, a hobby I picked up in the early 2000s with my dad, who first sparked my interest in computers. Fun fact: back in the day, I was Europe’s #1 ranked Battlefield 1942 player – proof that my competitive streak goes way back!

We’ve all experienced it. That moment after hitting send when you realise your email has been sent to the wrong person or contains a very noticeable typo. In the past, this meant resigning yourself to fate, but thankfully, Gmail offers a built-in safety net – the ‘undo send’ feature. 

What is the ‘undo send’ feature?

Gmail’s ‘undo send’ feature isn’t quite a “recall” in the traditional sense. You’re not able to retrieve an email from somebody else’s inbox before they open it. 

The feature is more of a window of opportunity that gives you the chance to prevent a very regrettable email from reaching an unintended destination. 

‘Undo send’ is a grace period that allows you to prevent your message from being fully sent. A simple feature that’s easily accessible and easy to use. 

How does Gmail’s undo send feature work?

When you’re ready to send an email and you click the send button, you’ll immediately get a small notification that pops up at the bottom of your Gmail tab. 

This ‘Message sent’ notification is worth paying attention to because it also includes the ‘undo’ button.

Once you see that undo button, that’s your chance to effectively “recall”. Clicking that button will unsend the email before it reaches the sender’s inbox. 

The beauty of this tool is that it’s customisable. Everybody’s reaction time varies, and most people won’t notice their mistake immediately. To combat this, Google allows you to choose from a range of durations in which you can ‘undo send’ an email. 

This doesn’t mean you can recall an email in Gmail after as long as an hour. Unfortunately, those emails can’t be recalled, but it gives you a little more time to realise any mistakes you may have made.  

How to extend your ‘undo send’ feature in Gmail

It’s fairly simple to extend the undo send notification if you’re familiar with Gmail.

Click into your Gmail settings (the gear icon in the top right corner of your Gmail) and then select ‘see all settings’.

You’ll automatically be on the general tab, so scroll down until you see the section ‘undo send’. You have the option to change the send cancellation period to 5, 10, 20, or 30 seconds. 

The more time you give yourself, the more likely you are to catch those mistakes before they are sent out permanently. 

Once you’ve made your selection, remember to click ‘save changes’ at the bottom of the page.

It’s worth noting, however, that when it comes to the Gmail mobile app, the default delay is 5 seconds, and there isn’t an option to increase the delay time. If you plan to send an email via the app, make sure you give yourself extra time to review it.  

A final thought

To get a true understanding of Gmail’s recall tool, you need to be aware that it’s not the same as other tools you may have used previously. 

It’s not a magic tool that will bring back your email from another person’s inbox before they’ve had a chance to see it. 

Gmail’s ‘undo send’ feature gives you a precious few seconds before disaster. By hitting that incredibly important undo button, you get to alter your email, however you need, before sending it on its way again. If you found this article useful, you might also enjoy Google Workspace vs Microsoft 365
