Aliases.
I can see the benefits of using aliases and I have a SimpleLogin account. However, I am unclear how, when I have multiple aliases, I would keep track of them on a daily basis when receiving and replying to mail sent to and replies from individual aliases. I tried one and received a response from a correspondent, but my follow-up email back to them caused confusion because the from field contained my ProtonMail address not the alias. How should it work?
