This is indeed critical for me as well. Is it a duplicate of https://protonmail.uservoice.com/forums/284483-proton-mail/suggestions/31264327-send-as-from-external-address ?

I use it daily on my Gmail account to manage my professional email address. This is absolutely a must!

This is critical. I thought it's standard to have this feature.

Recently subscribed to a Mail Plus Proton account with hope to finally get rid of gmail, but... no SMTP for my employer and university email! I think I will downgrade to a free account and for this feature to be available for non-business user. This is a key feature of Gmail.

I confirm this would be extremely helpful to manage other professional email accounts within Proton. This is the only thing that refrains me from switching to Proton to manage my emails.

Any chance that this is coming soon? For it would be a crucial thing before switching from Gmail.

This would be extremely helpful. +3

This feature is going to decide if I am going to switch to Proton mail.

Hi everybody,

a few hours after posting the message below, I realised this seems to be working?... I have defined the domain in Proton settings, some labels are still red but I have been able to successfully send a message from and to Gmail?

Does it work for you as well?

My family has its own domain name, whose MX currently forwards to Gmail all my incoming messages, and from Gmail I can use that "From" address for outgoing messages. It currently is not possible with Proton (just checked with support, see ticket 1906454) - I wish it was, so that I could extract me a bit further from Google's claws.

Hello,

I recently got a premium subscription, hoping not only to import my emails to proton, but also be able to sent emails from these email addresses that I do not own the domains (e.g. gmail - work emails).

Import was working somehow + usually forwarding, although not ideal. But not having the ability to sent was a major feelbad. This is critical for me to have my emails in 1 secure place and not use any other client/service.

(+ Maybe IMAP as well to automatically import new from providers that doesn't forward)

If a competitor would have similar security/client & would be able to do it, I would switch. I hope instead to get such a feature in proton.

The lack of this feature is the only reason I'm not switching completely to Proton. Alone in the migration process it is helpful. It also allows older and less important accounts to continue to operate.

Being able to "Send As" from one of the domains I have forwarded to ProtonMail would be extremely convenient.

Even more convenient—and important—would be if the "Unsubscribe" feature would automatically use the address to which an email was sent. Sending an "Unsubscribe" request from an address that is not on the mailing list is unproductive.

It would also be nice to specify "send as" with an alias (`+` SMTP feature).

My address is something@protonmail.com , sometimes I subscribe to websites with the email "something+websitename@protonmail.com" to track future spam. But sometimes they ask me to email them from my account's email, and I can't do that.

Any chance of this at any point?

This feature would allow me to move some but not all domain accounts to Protonmail by forwarding the moved ones to Protonmail and using this feature to send as that address. Other domain addresses could still be forwarded to Gmail etc. as they are today.

I also need this feature for various online services like forum or website administration.

It sucks to see this is still not implemented.

Like many users, this is the last missing tool that prevents me from moing all my mail to Protonmail
