Not sure. But Proton, Apple, passmail SimpleLogin (got names mixed up) and some other providers have a way you can create email aliases on the fly that forward to your real address. I think Microsoft does too but it was limited last time I looked at it.
There was one with a deformed tail at work. Poor guy could barely swim. Other fish picked on him. I’d make sure to drop food so he wouldn’t have to swim as far. He outlived all the other fish.
