I'm using an email forwarding service and want to send email so that replies are automatically directed through that service. As others have pointed out, this is a basic feature that is in essentially *all* email services since time immemorial. I just signed up for paid version and was very, very surprised and disappointed to find out this feature is missing.

Yeah, I'm going to update this to critical. I paid for 2 years, so you will be hearing from my quite often.
I *think* even mailx had this ability.

I have a business email and an alum email. When I send from pm.me, I'd like to be identified as either my alum or business in the "reply to" field. I probably should have asked before hitting the PAY button. Mea culpa!

Sheesh, even frelling Yahoo mail had this feature!

This is a fundamental feature of RFC-822 back in 1982. It's disappointing Protonmail team is focusing on "shiny new features" but ignore basic features preventing many of us from fully migrating from other services that support full and basic features. Kind of like spending money to add a theater and game room to a house while still using a wood burning stove in the kitchen.

+1!!! I try to migrate all my emails to proton Plus, but for the time being would be wonderful to have this feature!

This is pretty much an essential feature for me, I discovered this *after* upgrading (my fault). Would be great to hear some thoughts from the Proton team as to whether this is being considered

I discovered this shortcoming before upgrading from free. This is a deal breaker.

I still would like to see this!

I realy vouch for protonmail, really. But this request is already 2 years olds, and not even a sign of devs paying attention to it meanwhile it is a BASIC feature of all email provider. You're pouring resources into things like calendar and drive, and what is it even for if you are losing focus on the main product. I am a paid user and if there is no sign of milestone for this I'm moving on to the next provider.

Two years later: I'll be dropping protonmail if it doesn't have this feature on my next renewal.

That's not what "Reply-to" is for! What we really need is to be able to set the "From" header.

Please vote for https://protonmail.uservoice.com/forums/284483-protonmail/suggestions/18892543-custom-sent-from-without-custom-domain as that's more appropriate.

I just signed up only to find this isn't possible. Very disappointed!

YES!!!! I need this feature too!! I set my acct up in Thunderbird using the Protonmail Bridge and Thunderbird supports this, but Protonmail and the Protonmail Bridge do not so the send fails. VERY IMPORTANT. I can't use my alumni account with Protonmail.

This is the feature keeping me from switch totally to ProtonMail. I use an email alias either from my university alumni group or my professional society, and can't the way ProtonMail currently works.

I needed it today, and I wonder where this was hiding. It wasn't there, so I hope, and if I read back, is this request already for 2 years. So to bump this request, I hope that protonmail can do something for us. I also forward alias email addresses from a other domain, and I like to setup a reply to, for some aliassen.

+1, I've use an e-mail alias for 20+ years to allow freedom to move between providers. This is a critical feature after > one year requesting it.

The intent is that a "Reply To" address field on an e-mail would cause recipients to reply automatically via a ProtonMail alias address if specified by the sender. This way, the sender is more assured that the recipient will actually respond to the alias being supplied by the sender and not simply to the senders actual originating address field.

Just paid money for 1 year. Can't beleive that this feature doesn't exist!!!!!!!!!!!!!!!!!

Waiting for this for two years. I can't use proton mail without it. Moving on to another provider...

For myself (new here, just set up an account to try it out) there's little point in a catch-all if I'm forced to respond with one of my preset addresses.

I'd not only really appreciate a reply-to field, but if it could be prefilled automatically with the email address that was used to send it to my inbox, that'd be a huge bonus.
