We talked about Right Inbox For Scheduling And Tracking your Gmail Emails and now we have a similar service but with some nice other functions. Boomerang is an online service that allows you to schedule Gmail emails and remind you if nobody has opened the email in the specified interval of time which is decided by you. This means for example, if you want the receiver to read the email within 2 days and they did not read it, then you will be sent a reminder. Isn’t that useful ? You can also schedule your own inbox messages to be reminded of later. Below is a video which shows what Boomerang exactly does and how to use it.
Boomerang is free and fully functional for the first month. After that you will get 10 email credits per month or subscribe to any plans Boomerang provides you with. Download Boomerang For Chrome, Firefox or Safari
