Legit mail going into spam

Suddenly, without anything being different, my emails FROM MYSELF, and also my wife, to me, are going into the spam folder. We are both in my contacts list so I don’t understand how this can happen. I went to Gmail settings and made a filter (which I shouldn’t have to do) to NEVER put emails from these senders in the spam folder and it did no good. Any ideas?

Are the messages in the SPam folder in Gmail Webmail?

yes, they went to the spam folder at gmail too.
