I'm also having this problem with 2 gmail addresses. I've added to safe sender list several times as well as marking as not spam but they still end up in spam folder. Any suggestions please?
I have moved your post onto its own thread because you do not have the same problem as the OP of the thread you posted on.
That OP was not receiving any gmail emails from anyone where as your problem is that two gmail email addresses are getting to your email account but they are ending up in the spam folder.
Have you checked your safe senders list to ensure that the email addresses are actually listed there?
Do the gmail email contain anything that could be construed as spam?
