I use Hey.com's "catch all" inbox for this but it's a bit janky. If you set up a "custom domain" Hey account, you can actually email `[anything]@yourdomain.com` and it'll arrive in the catch all inbox. (Not unique to hey obviously) It has the benefit that it's impossible to block, but Hey obviously doesn't really want me doing that since they charge per-email-address.

I do this too, with namecheap.com's email servers... I pay for a few email domains on namecheap, but one is specifically for spam, and I use their "catch all" as well.

So if I sign up for a service like amazon.com, my email address will be amazon.com@[my-spam-domain].com so I know exactly who is selling my email address. I do this for every service that asks for an email address.

I'd never use a "plus" email address from my main email account, which is far too easy for spammers to figure out my real email address from.
