Timing can be everything – unfortunately our lives seldom let us attend to everything at the perfect pace.

That's where Boomerang for Gmail kicks in.

Boomerang

Boomerang is an extension for Gmail that lets you schedule your messages to send at a later time.

It's super easy to use: just compose an email as you normally would, then select the "Send Later" button.

Boomerang then brings up a calendar or a text box to pick the right time to send. Boomerang also understands language like "send next Tuesday".

Boomerang also reminds you if you don't hear back from specific emails, and can set up Follow Up reminders. 

There are also a bunch of other handy features, including birthday and bill reminders.

Boomerang is available on iOS and Android.
