Review for Send Later by itamarh
Rated 5 out of 5 stars
I find it really useful for both postponing items to later, reminders and recurrent emails.
Would be great to also see a "snooze 1 day" button, which basically forwards an email to self one day later and deletes the current item or something like that.
(well, nicer if it actually hides the original email for a period of time, but that sounds like a different extension)
Thanks for this useful extension!
