SAN FRANCISCO — Gmail is rolling out a popular feature that it has been testing for years: Undo send.

The feature delays sending an email for five to 30 seconds in case you have second thoughts.

It has been in beta since 2009 as part of Google Labs, a set of features that the public can try out even though Google isn't quite ready to release them.

Google announced this week that "undo send" has now become an official setting in Gmail. In May, the feature was released with Google's new version of Inbox.

You can choose to hold off sending an email for as long as 30 seconds, but only on the Web. Undo send is not yet available on mobile devices.

If you already have the feature turned on, it stays on. If not, you can turn it on by going to the "general" tab under "settings."

Gmail is the world's most popular email service with 900 million people using it around the globe.
