I have a personal domain and I use a mail account on it (it's not Gmail). Recently, all the emails I send (personal and business messages, not bulk) keep getting into the recipients Gmail Spam folder (I checked with several recipients).
Why is that and what can I do?
I checked and my domain is not in the blacklist.
When looking at the message in the Spam folder, it states "It's similar to messages that were detected by our spam filter". However, this is a personal message I wrote to someone - not a newsletter or a bulk message.
My sites and mail server are on a shared hosting service. But until recently I didn't have this problem.
