Merging duplicate issues together is at least an acknowledgement! Were the votes of this issue automatically bumped by the number of votes on the other issue that was merged into this one? The last time I went on a deep dive to find all the times this was requested they had over 600 cumulative votes. Following through all these links now some appear to just be deleted while others are merging into this one. I'd hate for all those other votes from other issues to suddenly be lost as a result of this consolidation and then the company say "well only 51 votes it's not as popular as other suggestions."

This one alone has over 360 votes - https://protonmail.uservoice.com/forums/284483-proton-mail/suggestions/31264327-send-as-from-external-address-add-support-for-e

Dear Proton Mail Product Team,

Thank you for continuing to deliver a secure and privacy-respecting communication platform. As a dedicated Proton Mail user, I appreciate the progress you’ve made with encrypted email, calendar, and multi-account support.

I’d like to request a feature that would significantly improve the Proton Mail app’s functionality: support for adding and managing external email and calendar accounts such as Gmail, Outlook, Microsoft 365, Yahoo, and others.

This feature would allow users to:
• Access and manage all email communication from a single, secure Proton Mail interface
• View and manage multiple calendars in one place, simplifying scheduling and planning
• Reduce reliance on third-party apps and improve overall workflow efficiency

I understand Proton’s focus on privacy and security may introduce challenges with integrating external providers. However, even basic read-only support for external email and calendar accounts would make Proton Mail much more versatile as a central communication hub.

Many users today rely on multiple providers for work and personal communication. Giving us the ability to consolidate that into Proton Mail would be a meaningful step forward and would likely encourage wider adoption of your services.

Thank you for your time and for continuing to build a product that puts user privacy first.

This feature is what is missing for me to transition to proton.

If it does not appear, I might leave again, as it is too much of a pain to keep track of several email clients.

I am now coming across more and more companies that will only accept emails from the email registered with the company

I would find it very useful to have the ability to reply to an email addressed to a gmail account where that gmail account is that registered with the company

Currently I read the email in Proton but then I have to go to gmail to reply

As the customer I should be able to decide what security I need based on my threat model not what Proton thinks it knows about me and my threat model. I signed up for Duo and find the iOS Mail map doesn't work because Proton doesn't supply IMAP/SMTP over TLS which eliminates 99% of the threat. I am leaving companies that decide to solve things in a proprietary way without industry standard options.

Mostly repeating what others have said below, but the pain is real.

I have a paid Proton account for about a year (including all the other services). I really enjoy it, especially ProtonPass. ProtonMail unfortunately doesn't get as much attention as I had hoped (main reason to start using the Proton package to begin with). I'm using the alias feature a lot for random website accounts, but for my personal mail I still haven't switched from gmail.

The main reason is that I will have to keep sending email with my gmail for a long time until I would be fully migrated. Currently this means I will have to use two web clients which I really don't like. Right now, protonmail is the loser here and I am not using it for serious mail.

I'm considering starting to use a desktop mail client (that can combine the inboxes), but this would not help me on my mobile phone. So I doubt if that would be what I want.

So yes, sending (some) mail unencrypted via gmail is not what we want, but it is an intermediate step. I believe that many people like me basically are ending up in a worse state where none of the mail is encrypted because they can't migrate away from gmail..

So big +1

This feature is essential! For example, I’m part of a Society that provides us with email addresses. With Gmail, I can send and receive emails from that address, even though they’re being forwarded from the Society’s server to my Gmail account. Using Gmail’s free SMTP feature, I can send emails as that address without the recipient knowing it’s forwarded. Having this capability in ProtonMail would be a game changer!

This feature is not a big thing to do, I'm currently considering to moving to Proton mail and my only set back is the lack of external pop3 mail fetch from other accounts (e.g.: My work mail policys not allows me to forward my e-mails to anywhere, that's why I have to use pop3 to fetch mails from my work e-mail on regular basis (few minutes is got 1-10 minutes).

Also it would be greate if you would allow using external e-mail addresses, which is connected with the pop3 account, to use it's external smtp server for sending mails with that account.

This features are available in free gmail, please make this happen.

I believe this is required functionality for me to truly make proton my main hub.

This would make it even easier to "transition" from gmail, yahoo, anywhere.

The title may not be clear but it could be cool to use Proton Mail to send emails from another email address as Gmail does. You Just have to connect your SMTP and IMAP account from your email provider and every thing appears in your inbox so you don't have to connect to multiple websites to view your different inboxes

I have nearly 20 years of using GMail. I won't be replacing my gmail addresses with Proton address in all the myriad of places and contacts who have it. The "send as" feature where I can configure SMTP settings for my personal domain and then use a single mailbox to send as any of my GMail and personal domain emails is pretty much the one thing that keeps me using GMail instead of Proton. I don't actually have _any_ correspondence with other protonmail.com or proton.me mailboxes, so the E2EE between Proton mailboxes is already a moot point if I'm only really sending emails from Proton to external mailboxes. There seems to be quite a few requests for it, too, if you search over in the Proton subreddit.

It would be good to be able to collect mail from other mail provider on a regular basis.

e. g. yahoo mail does not provide forwarding to other accounts like proton. So I would need to collect/fetch mail from within proton using pop3 or imap credentials of yahoo.

currently proton does not support this and I need to use e. g. gmail to fetch from yahoo via pop3 and then let gmail forward to proton.

this is inconvenient as I'd like to manage email accounts as "directly" as possible

Support integration of custom domains in ProtonMail to allow Send/Receive from these emails. Effectively a high security Outlook.

This is impossible. It completely opens up your emails in plain text to be sent wholesale through IMAP/POP and SMTP. This is why there is a bridge app, so you can open emails on local machine without sending across a network unencrypted. This is not at all important.

While I understand that protons first goal is to ensure privacy and emails from other providers like outlook or gmail cannot be as private as emails that run directly through proton it is a hard truth that most of us are still forced to use gmail or outlook.

Mostly because of work, but there are surely even other reasons.

For proton to ultimately become the “main hub” I believe it should allow users to send and receive emails from other providers through SMTP and IMAP/POP

The user is responsible for this and should understand that sending emails through these accounts are less secure. Proton should still allow it, in the end the user bears the consequences of their own decision.

And while Proton cannot ensure the privacy of those emails they can still provider some services like checking trackers and other services with emails from those accounts.

Allowing this would finally let me achieve the goal of using proton for everything.

It would also be easier to convince others to switch to proton as the initial switch would not be so harsh since they can still send and receive emails from their current accounts making the switch more seamless.

It would be really great for Proton Mail to be able to act as an e-mail client, and being able to fetch e-mails by other providers (not only Gmail). Some kind of redirection, but which could be initiated from Proton Mail and *not* from the other provider.

I am critically missing the ability to get email synchronization over IMAP from other service providers. Now there is an import - but this is a one-time opportunity. I want to receive mail in the same way as an email client, so that the data is automatically received via IMAP as soon as a new email arrives.
