In my Proton Mail, I have total of 90 aliases with Proton Family account. With Unlimited account I have only 15 aliases, and that includes aliases on my custom domains. It provides SL Premium but I gave up with it.
Oh I see, I thought you were talking about the alias generated via Proton Pass. For the âaliasâ created under account settings page is not designed to be disposable ones so I think it is okay to have a smaller limit on it.
It is understandable for limiting aliases on Protonâs own domains but it doesnât make any sense to put a limit on custom domains.
And, if you want to sent an email from an alias, you need to create a contact in SL admin page one by one, and then you can send an email. Send emails from your alias - SimpleLogin Docs
It should be easy like sending emails from Proton aliases, but nope. Proton decided to put a very low limit to Proton Mail service and forced people to use SL.
