Those are aliases, not addresses. I'm on a paid plan and also cannot edit the sender field to be these. That is only for different addresses.
You probably want SimpleLogin. I'd check that out.
Simple login will appear as from the alias when you respond to an email received through that alias. It does not however (IIRC) change the sender field that the user sees from your default.
Sure, but we're talking about being able to select a Sender from the ProtonMail UI. It would be awesome if PM could do that, and it's a highly requested feature. That would basically be the same as having it integrated so that the PM UI could allow you to choose a reverse SL alias when sending instead of navigating to SL, creating it manually, then copying and pasting into the To field.
Ok, thanks for confirming. I'll check out the alternative.
You should submit a feature request for that. It is possible to send from the aliases on other platforms; might just be something their devs need some critical mass to work on.
I guess I'll do, since it's sort of a deal breaker at this point.
