Ah, the problem. I have started using my custom domain and a random username for each service, derived from the service's domain. Pretty easy way to not give away your email.

I do this as well, but it's a lot nicer (and actually private) to have a random @privaterelay.appleid.com.

It's private, assuming we trust Apple. For now Apple is privacy friendly, but this might change in a couple of years.

Thanks for the kind feedback! Yes I'm looking into a few of these options at the moment

One I've just been given is metomic.io/alias which looks to solve that
