Baydin (the company behind Boomerang) has just announced that users can reschedule messages inside Gmail once they have already been scheduled.
Boomerang is simply indispensable, especially if you are dealing with a huge number of emails every day. In a nutshell, you can tell it to remove emails from your inbox and return them to the inbox at a certain day and time in the future. You can also request read receipts from the recipient and send the email at a later date. Perfect for fooling the boss into thinking you’re working late.
So, what does this new update mean? Basically once the email has been told to come back at a certain time and it disappears from the inbox, you can go to that email (either in the sent folder or in “All Mail”) and easily change the return date.
Plans change, especially in busy offices. Maybe you suddenly don’t need the agenda tomorrow, but urgently at the end of the week instead? Or maybe you don’t need to see an email anymore and you want to cancel the return command in Boomerang? Now you can easily adjust the return date to keep things the way they should be. No fuss, no stress.
Another small change is that messages which are returned to your inbox are now labelled “Boomerang-Returned” which makes it easier to see which ones have come back, as per your request. This option can be switched off in the Boomerang options, if you don’t want it.
