iCloud mail: Is there a way to block emails from an address for a week?
As Richard Dickins you can set a rule on the server this can be done on iCloud as well as Google and I think on most others.

You create a new folder and set a rule to send the mail there so not in inbox or showing a notification or adding to the count of unread,  but you have to add a separate reminder say in Calendar setting the alert as an email to remind you to read the mail.

You can also do this on OS X mail if that is the only mail reader you use, this can be automated with Applescript to copy these messages back to the Inbox
