Google Tweaks Gmail’s “Undo Send” Labs Feature

One of the things that I love about Gmail is Gmail Labs, the experimental (and often useful) add-on features that you can enable through Settings -> Labs or via the little green flask icon next to your email address at the top-right of the screen. One of the most useful Labs features is called “Undo Send.” Ever hit the send button on a message and then immediately regretted it? Undo Send stops the message from being sent for a few seconds, which enables you to change your mind if you hit “Send” too soon.

Originally, the delay on “Undo Send” was set to five seconds — just enough for you to catch those emails where you immediately regret clicking the send button. But Google’s now tweaked the feature, so you can specify a longer delay (5, 10, 20 or 30 seconds) via “Send cancellation period” on your Settings page:

Obviously, setting a longer cancellation period will give you more time to realize that you didn’t actually want to send an email, but will also add a longer delay before your emails are sent.

What’s your favorite Labs feature?
