How can I unspam Facebook from my Gmail?

[Puss in Boots]

I set it so Facebook will send me emails whenever I recieve a notification. I accidentally spammed Facebook though so I don't directly recieve them anymore.

How do I undo this?

Thanks.
Where is the "mark as not spam" option? I see "mark as read" or "mark as unread"

you can you accidentally marked facebook as a spam sender on your email account?
if that's the case, you can unfilter facebook from your email account, since I dont know which one you have, just go to settings and see if you can find it. If you have gmail like I do, just go to your spam folder, click on the facebook email and click "mark as not spam"
