I never tried this myself, but you got me curious. Since Proton uses SimpleLogin to handle aliases you should be able to use this from their docs to achieve this (you can login into SimpleLogin via proton if you never did) https://simplelogin.io/docs/getting-started/send-email

Thank you, i will test it out! Just now, i did saw on a forum that through proton pass, apparently it's not possible to actively use it as a mail address, only replying seems to work. I have no idea whether this is inherently how aliases work, or whether it is something that proton could implement in time.
As a work around, what if you sent your alias an email from your real address, then replied to that but changed the recipient to the company you want to contact. Then obviously delete the quotes text at the bottom. I don't know if it'd work but please report back with results.
won‘t work, since SL will not pass your sent e-mail to your own mailbox.
But you should be able to start a conversation with your alias from SL itself.
But he's asking about aliases created in Proton Pass not simple login
I will try this, but it might take a long time before i need to try it. For now, i replied to them, because replying seems to work.
