The latest operating systems allow you to "hide" your email address ...

Start filling in your email address in a box, it will suggest hiding it by creating an obfuscated address that your message appears to come from, hiding your real address.

Apple collects your incoming mail at that address and forwards it to your desired inbox.
The "other guy" only sees that "created" address, which you can prevent from forwarding later on.

It's like creating a bunch of incoming email addresses, but these forward to your regular inbox per your request and can be deactivated easily.

I have been using getnada.com for incoming-only emails (like when a site demands that you give out an email address to get some freebie). Go there and it creates one for you, or you can choose a more memorable one.

Send that address to your likely spammer, and their reply will show up in the getnada malbox. IT IS NOT PRIVATE. Anyone who knows it can read it, but it's a throwaway. Basically one-time use.

Later emails/spam go to it but you can just ignore them (I forget the names of the inboxes) and mail to them is deleted once a month, IIRC.

Besides getnada, they own a bunch of domains, so you can choose another.

HTH


P.S. Every email client/service has some way to block incoming spam selectively. So you can keep that favorite address. Details vary, of course.
