To unsend an email in Gmail, click Undo in the Message sent box at the bottom left straight after sending. Gmail has no true recall: you can set a 5, 10, 20 or 30 second window on a computer, and once it passes the email can't be pulled back.
We've all hit Send a second too soon: wrong attachment, wrong person, a typo in the first line of a pitch. Gmail does give you a way out, but it's a short window, and a lot of advice online makes it sound more powerful than it's.
This page covers both versions of the question, since people search for 'unsend' and 'recall' for the same thing. I've stuck to what Google's own help says, including the part nobody wants to hear: once the window closes, the message is gone for good.
Unsending a sent email in Gmail on a computer
Undo works only right after you send. Google's steps for a computer are:
- Send your email as normal.
- Look at the bottom left of the screen. You'll see a box saying Message sent, with the options Undo and View message.
- Click Undo straight away.
Your email isn't delivered. It reopens as a draft so you can fix it, which is the whole point. If you walk away from the screen even for a moment, the box can vanish and so can your chance.
Recalling a Gmail message from your phone
Google's help for Android and iPhone describes the same thing. Right after you send, you'll see the word Sent and an option to Undo. Tap Undo. As on a computer, it's a brief moment, so keep your eyes on the screen when you send anything important.
The truth about 'recall' in Gmail
Searchers often type 'recall an email in Gmail' because they've used the Recall option in other mail programs. Gmail doesn't work that way. Google's help describes Undo Send, a short delay before delivery, and nothing that pulls back a message once it has gone out. If the window has passed, you can't take the email back.
So the honest answer is: set yourself up so the window is long enough, then use it when you need it.
Making your Gmail Undo Send window longer
On a computer you can change how long Gmail waits before it really sends. According to Google:
- Open Gmail on your computer.
- Click the Settings icon at the top right, then See all settings.
- Next to Undo Send, pick a cancellation period of 5, 10, 20 or 30 seconds.
- Scroll down and click Save changes.
| Cancellation period | What it means |
|---|---|
| 5 seconds | The shortest window, quick but easy to miss |
| 10 seconds | A little breathing room |
| 20 seconds | Handy if you re-read before moving on |
| 30 seconds | The longest window Gmail offers |
I'd choose the longest one. A delay of half a minute is hardly noticeable for most emails, and it's the moment you spot the wrong attachment. Google's help describes the setting on a computer; I haven't seen it stated for the phone apps, so I won't claim it.
What you can do after the Gmail Undo window has passed
When Undo is gone, you're limited to damage control. None of these take the email back, but they help:
- Send a short follow-up straight away. A calm 'Sorry, wrong attachment, please ignore the last one' works better than silence.
- If you included something private, phone the person and ask them to delete it.
- If it went to the wrong recipient, say so honestly. Most people will help.
- If an email contained a password or sensitive login, change that password at once.
Checking an email before it leaves Gmail
The best unsend is the one you never need. Before you click Send on anything that matters, read it out loud once. You'll catch the clumsy sentence, the missing name and the wrong date. It takes less time than writing the apology.

I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Add the recipient last, attach files before you write the final paragraph, and keep important replies in draft until you're calm. These tiny habits do more for you than any setting.
Scheduling a Gmail message instead of sending it now
A related option, if you want control without racing a countdown, is scheduling. Google's help for the iPhone and iPad app says that when you cancel a scheduled email, it becomes a draft. That gives you a gentler safety net than Undo, because you can open it, check it and reschedule. It's a good habit for important client proposals.
Unsending emails when you run a small business
The risk of a wrong send is bigger when it's a customer, supplier or journalist on the other end. Some habits I'd build in:
- Fill the recipient box last, so you can't send half-finished by accident.
- Re-read the subject line, not only the body.
- Check the attachment name and open it once.
- Use the longest Undo Send window.
- For anything sensitive, schedule it and review it again later.

If you can't see the Undo option in Gmail
- Look at the bottom left of your screen right after sending, not at the top.
- Check the Undo Send setting. If you've left it at the shortest option, the box disappears quickly.
- Make sure you sent the message. A saved draft has no Undo box.
- Try a different browser or turn off extensions that might hide pop-ups.
- Update the Gmail app on your phone.

How do I unsend an email in Gmail?
Click Undo in the Message sent box that appears at the bottom left straight after you send. On Android and iPhone, tap Undo next to the Sent message.
