I do.

I use SimpleLogin and ProtonMail.

Some sites have I’ll actually know you’re using SimpleLogin though and just say no, but they’re few and far between.

You could also use your own domain if you have one or buy a cheap one.

Then you can create as many as you like and just kill them as and when you need.

SimpleLogin has plugins for all browsers and phones so it’s not too difficult to create new addresses.
