Send emails at the perfect time

A well-timed email is 30% more likely to be read than a poorly-timed one. Boomerang's send later feature lets you write a message now, then have it delivered whenever is best, without keeping your computer on.

Recurring Messages in Outlook

Schedule recurring messages

The recurring messages feature puts sending out repetitive emails on autopilot! Send a timekeeping email every Friday, a reminder to update Salesforce at the end of every quarter, and remind yourself to check in with a prospective client the first day of every month.


Share your real-time availability inside an email

Embed your free/busy status inside an email that automatically updates as your schedule changes. Recipients can use any mail system, and it just works - even on mobile! Only your free/busy information is shared, and the links expire, so your privacy is always protected.


Eliminate human errors from meeting scheduling

Scheduling meetings happens via email - Boomerang makes email good for scheduling meetings without errors! Look up your schedule/agenda for the day without having to switch windows and try to remember which times were suggested. Most importantly, Boomerang prevents you from accidentally double-booking yourself.

Know when your email gets read or clicked

With Boomerang read receipts, you can get notified both when a recipient opens your email and when they click on any link in the message. You'll be able to follow-up (or not have to) knowing whether your email was read. And unlike most email tracking software, Boomerang's read receipts respect privacy, reducing the chance your email is marked as spam.
