I have the Proton Unlimited plan so I’m using all their services. I create a new email alias through Proton Pass, which uses SimpleLogin, for every site I sign up for. If I receive an email through the alias in my Proton Mail inbox, and I reply to it, it goes through the alias and doesn’t expose my true email address.

All very easy to setup and do.

Alternatives: Discord DM sound, Microsoft Teams notification sound
