I put facebook in my contact list but their mail still goes to spam?

[plantsrocksandfish]

A group is using facebook to send messages to members. I want to be sure I receive them. I go to Spam and mark the mail as not spam. New mail still goes to spam. I added facebook to my contacts, still goes to spam. I went to filters and set up several options, still goes to spam and of course I checked my blocked addresses. Not there. Any ideas?
