Introducing ProtonMail Professional – Encrypted Email for Organizations

protonmail professional

Today, we’re happy to announce a brand new ProtonMail plan. With ProtonMail Professional, encrypted email is finally available for organizations.

When ProtonMail first opened to the public last year, we launched with three plans, Free, Plus, and Visionary. Since then, millions of people have moved their email to ProtonMail and benefited from the security and privacy that comes with end-to-end email encryption. Today, we’re happy to announce a fourth ProtonMail plan, Professional.

Encrypted email for Organizations

ProtonMail Professional brings with it a much demanded feature that a lot of people from the ProtonMail community have been asking for since the very beginning. With the Professional plans, not only is it possible to use ProtonMail to host email for your domain, it is also possible to create individual user accounts for people within your organization.

The Professional plan comes with a set of powerful management tools that allow organization administrators to manage the accounts of organization members. With ProtonMail Professional, you can create administrators for your organization which can manage regular user accounts. This includes things like provisioning new accounts, allocating organization storage space between accounts, resetting passwords, and much more.

Best of all, ProtonMail Professional does all this while preserving the end-to-end email encryption that ProtonMail uses to protect your privacy. Professional plans allow you to extend that protection to your entire organization. With ProtonMail Professional, all emails exchanged between members of your organization benefit from automatic and transparent end-to-end encryption, meaning that even though ProtonMail is hosting your emails, we do not have the technical means to read your organization’s email communications, and cannot hand them over to third parties. Because we can’t read your emails, this also means that if ProtonMail servers are somehow compromised, your communications will still be protected because attackers cannot steal from us data that we do not possess in the first place.

Managing an encrypted organization

ProtonMail Professional manages to do all this while still making it possible to manage your organization. In other words, while all organization accounts are end-to-end encrypted, it is still possible for organization admins to access the emails of other organization users. Thus, organizational oversight and management is still possible, even with end-to-end encryption. Furthermore, administrative read permissions are also granted or revoked automatically when admin users are created or demoted.

This is made possible by a highly sophisticated organization level key management system which manages the keychain for the entire organization. However, all this complexity is hidden from the user. In fact, you can manage your organization’s encrypted emails without even knowing what an encryption key is, while still benefiting from the security provided by strong encryption. The flexibility and power of our key management system also means that private users can also be created if certain members of your organization need more privacy (private users are users whose emails are not accessible even to admins).

Getting started with ProtonMail Professional

To get started with encrypted email for your organization, you can upgrade to ProtonMail Professional by going to Settings –> Dashboard in the ProtonMail web interface. We also have created a comprehensive guide on how to get started with ProtonMail for Organizations.

Over the coming months, we look forward to continuing to enhance the features and capabilities of all ProtonMail plans so that we can make encrypted email a reality for everyone, from the individual user to the largest organizations.

Best Regards,
The ProtonMail Team

  • Great news, congratulations! I know that you’re working on IMAP access but IMHO you don’t want to leave that too far down the roadmap (and/or some kind of export procedure), because organizations just won’t move their domains to ProtonMail without a reversibility procedure. This is an impressive technical challenge that you’re taking (I don’t believe anyone’s been ambitious or visionary enough to try that), but anyhow organizations will want both security *and* reversibility (believe me).

  • IMAP will be great for businesses.

    ProtonMail is a competitive advantage. Your competitors may not realize they are open to having their records combed through word-by-word by lawyers. You can opt out of this if you wish, but most people don’t know about this yet.

    And thanks for working on streamlining the search function! That was number 1 on my wish list.

  • Errors’

    “millions of people have move”

    should be

    “millions of people have moved”


    “while still benefit from the security”

    should be

    “while still benefiting from the security”


    “and still benefit from the security”


    “who emails are not accessible even to admins”

    should be

    “whose emails are not accessible even to admins”

  • Can we have a plus family plan? I’d like to have my SO join protonmail but she’s not that tech savvy to setup herself so would love to have a family plan for separate inboxes. Thanks for the hardwork!

  • Great step forward, but a switch will not be made until POP access (not interested in IMAP) with an email client is available.

  • “attackers cannot steal from us data that we do not possess in the first place.”

    Should be

    “attackers cannot steal from us data that we can not unencrypt in the first place.
    Since you do possess the encrypted data. Don’t you?
    Also I kept getting errors redirecting me to a centos apache page a week or so ago. Why not use freebsd or something along those lines?

  • I would need to be able to back up my data to switch all my company emails to ProtonMail.

  • Please clarify if an email account with Proton can be used to send and receive emails from accounts that are not with Proton.
    For example, could I send and receive emails (to/from my Proton account) to my friends and family that use Gmail, AOL, Hotmail accounts, etc.
    Thank you

  • How do you contact this company when theres a fraudulent purchase on your card with this company?

  • Hi,

    I’m trying to create a basic free account to begin with. Filled up all the required info but stucked on the page. Using your desktop version.
    Is the service still available ???

  • Hi,
    I would like to know if with the professional subscription a company mail can use its own domain domain name, instead and over
    Many thanks

  • Nice guys (gals inclusive on that!)!! My apologies for this belated ‘Congrats;’ I have been a bit behind on nearly all aspects of life. This is awesome. And will be mandatory (or nearly; dependent) for all my clients… AND even more so, for the field I am looking to ease into.
    I’m noticing a few more folks here and there having heard of PM… and it makes me nervous, lol. If you guys get extraordinarily big – will it be more difficult to do what you do (forgive me again – I do not know code, nor IT, nor any of the like!)??
    Either way… yay for YOU!! =)

  • Do you have a process in place to allow a full migration of content, past email history, from Yahoo, Gmail or Outlook into a new account with ProtonMail?

  • Hello!
    Thanks for your great services! I use it every day and I like them. They are very useful and help me to protect my privacy online.
    As an individual, I think that now the biggest risk impacting my privacy is my password manager. If the password manager that I use in not safe then my ProtonMail account could be at risk as well.
    It would be so great if your team could offer as well a trustable password manager or recommend one.
    Would it be possible?

    • Hi Mathys,
      You make a good point. A strong password is the first line of defense for your accounts.
      While there are many perfectly good password managers out there, Bitwarden is one of the only ones that is open source. And you know how important that is to us.

  • I would like to stop the spying o my home office. I’ve noticed while my PC is on in my office, an employee comes in to talk. 2 minutes later advertising shows up on my screen related to our conversations. 1. How does this happen? How can I stop this?

    Kind regards

    • Hi Gerald, unfortunately big tech companies have many ways to predict your interests, most of which don’t involve listening to your conversations.

  • Hi there,

    I have a protonmail account with a user name –

    l have recently forgotten my password for the above mentioned email address as I lost my android phone that I was using for accessing this email. I have a recovery email address as well. I have been asked by protonmail support team to provide information as-


    Thank you for the follow-up.

    Could you please provide us with more precise number dates for our first two security questions (last login and creation)? The answers you provided are not specific enough. Please do your best to provide us with estimate number dates in the following format: 08-Jan-2020 – if browser history is not available. You can also check the date you received your confirmation email or SMS, if you used these methods to signup for your account.

    Please take your time with the dates as they are key.

    We are also including additional questions to further verify your ownership, these are not meant to substitute for the dates:

    -Is your account using One password or Two password mode?
    -Do you have a short address added to the account?
    -Have you used the ProtonVPN service with this account?
    -Did you subscribe to any services or websites using this account? If so, which ones?

    Looking forward to your reply.

    Best Regards,
    The ProtonMail Team

    I lost my phone and how do I give them precise date. This is going on since a month.

    I am trying to reset the code using this email address but I have unable to receive a code in my email.
    I have given them my recovery email address as well.

    I am not getting any response.

    Your assistance will be highly appreciated.

    Kind regards
