Google announced on Google+ about the new feature that allows webmasters to control the messages they receive in Google Search Console.
It’s very simple to use:
1) When you receive a message you’d like to disable, click “Unsubscribe from this type of message” in the footer of the email.
2) Messages you’ve disabled will be listed in your Search Console preferences page — just like on the screenshot below.
3) You can re-enable messages from there as well.
