Too many emails are sending out.
Users are subscribing all the questions and comments. Also mentioning each other in every posts. So thousands of emails are sending out per day. Moreover there is no option for a user to unsubscribe from mentioning. So now I disabled all emails except registration confirmation and password reset.
It would have been nice to notify a user by aggregating all notifications per day or once in 12 hours or so.
Any way to do this or something similar to this?
