Have you invested time in tweaking your settings to have all promotional emails bypass your main Inbox? I use GMAIL and so not know how other webmail providers set it up but am sure they have competitive offerings. I very rarely get a spam email: maybe once a month, and then I categorize it as spam and emails from that sender get blocked, plus the AI (called spam classifier: that algorithm that categorizes incoming email into spam and legit) has learned something from my pointing to it that it missed a spam email.

Calls: have been on a Do Not Call list for years. Plus, Verizon must be doing something to block or at least flag potential spam calls. It is not perfect and sometimes I call back to verify. Usually it is correct but on Monday an advice nurse called me to check on me as I was having a short lasting reaction to Prevnar and her line was miscategorized as potential spam. I called back and later added her number to my contacts which will prevent blocking in the future as having a number in one's contacts means it is legit.

With texts, sometimes they come through but mostly after you send STOP in response they won't persist.

Some years ago I read that the Do Not Call registry has been the most successful consumer program of the Federal Trade Commission (the FTC). I do not know if that has changed, but all of the above methods, taken as a whole, work for me and most annoyrances do come via USPS as Sarah has complained about. I do not know what to do about USPS junk.
