An Outlook add-in that feels like a native part of Outlook:

Boomerang integrates directly with the Office ribbon, as if it were a native part of Outlook. This means you don't have to leave the email you are composing to schedule it to send later or to add click tracking to it. And the ribbon provides features for when you're reading an email too.

Outlook Ribbon Integration

Got a boarding pass but want to snooze it for later? Just click the "Remind Me" button Boomerang adds to the Outlook Ribbon. Unsure if you're free for a proposed meeting? Hover over the meeting time, and Boomerang will show your availability without you needing to switch to your calendar. And then there's the powerful calendar assistant that helps you embed your real-time calendar availability into an email that works with across email platforms, even on mobile! We bring these features everywhere you go with support for Outlook.com and Outlook on the Web!
