Do SimpleLogin's aliases use your custom domain and/or does it use sub-addressing (plus addressing)? I wonder how much longer they'll offer that price given Proton's plan for those features is $10/mo, limited to 15 email addresses and the unlimited aliases are randomly generated.

They can use whatever custom domain you want & either have them generated randomly, or you can have them be unique as well. I hope they offer that price indefinitely. Good thing it is open source as well.
