Do you know why you’re getting junk mail? Are you signing up for stuff using that email and the companies are sharing your info? Create a separate account for that.
I’ve had someone online deliberately sign me up for junk mail. It was kinda creepy and pretty annoying. I just kept reporting spam/sending to junk, and eventually it slowed down and stopped. A few slip through every now and them, but not enough to be a problem. Getting on the mail mobile app and selecting junk mail made it easier to delete and organize.
