Please give me an advice.
My email suddenly go to spam box while the previous campaigns for 4 months in a row were very good. Open rate over 50% and Click rate above 2%. But suddenly I sent an email today and both of these campaigns went to the spam box. Everything I do is as usual. There's nothing different. Even before sending the campaign I checked by sending to https://www.mail-tester.com/ and got 10/10 points.
Please take a look and let me know the possible reasons why my campaigns got into the spam box.
