SimpleLogin too. Create aliases even more… aliased (aliaser?) .

I use them for extra control with some things. Example: I may have 5 main proton aliases each for a different thing like shopping or banking etc. Then sign up for Zillow House hunting emails with a SimpleLogin alias which forwards to one of the proton emails. When I’m done house hunting, I turn it off and they never had my regular one to lose in a hack or restart marketing and sell.

Too much work for me personally, to use one for every site but it’s great for any heavily email traffic like political donation emails or a site with heavy notification emails.
