@helem I don't know which email provider you are using. I use gmail. There is a Spam folder where some of my legit messages would go. I can also set up different sub-folders/tabs in my Inbox to separate messages into Primary, Social, Promotion, etc. From time to time, messages would go to wrong sub-folders as well. What I do is to immediately move the messages to the correct folders/sub-folders. It looks like if I do this repeatedly for a few times, the email server is smart enough to get things right after a while. The ones that fall into the Spam folder incorrectly, I have an option to click Not Spam to move them out into the Inbox. If you leave the things as they are and just open them there, they will keep going there because the email server will think that is the right place to put them.
