I very aggressively unsubscribe from everything so I get very little mailing list spam. Maybe a few messages a month.
What I do get _constantly_ is spam email messages to my inbox from Gmail and Outlook domains. At least one a day for many years. Because it from Gmail, they have very little spam filtering done, yet if any other provider sent these messages then Google would block the entire domain.
These particular spam messages get on my nerves, and these are the only ones making it through to me.
