I just got done switching from gmail to fastmail, and it solves this problem beautifully with a nifty feature allowing me to create a new proxy (“masked”) email address for every website but have the mail show up in my mail address. There’s a limit, but it’s like 600+ or something. So when the email gets sold and I start getting spammed, I can easy kill it, and also know who the culprit was.
This one is paid, but I’m at the point where $140 for 3 years “standard” package is fine by me. Not to mention I can actually call someone if I have a problem, instead of getting blocked by google for no particular reason without any recourse. I don’t have a huge social media following that can get me special treatment.
There may possibly be free options that allow you to proxy/mask emails, but I’ve not explored that.
Another useful service is privacy.com, which in a similar manner let’s me create proxy virtual payment cards, setting limits and redacting cards. This kills the possibility of a malicious business like a telecom still charging me for something and having the bank still allow it to go through when they shouldn’t. Now my credit union is pretty good so far, but there are a lot of banks that will happily fuck someone over without a care.
It’s nice having no mean _No_
