What are custom domains?

Custom domains offer you a way for sending messages from other addresses other than @protonmail.com. You can use your own domain with ProtonMail, and send messages from the addresses you add.

If you have upgraded to a premium plan, you can use a custom domain within ProtonMail and enjoy all the benefits of seamless end-to-end encryption! You must have access to the domain’s DNS records so that you can change them to point to ProtonMail. Unfortunately, this means you will not be able to add addresses from domains you do not own or control, such as .edu or .gov domains.

If you don’t have your own domain yet, you can buy one through domain registrars like namecheap.com. Domains that are not taken yet can be quickly acquired and typically cost around $10 per year. Let’s assume you have the domain funoccupied.com, then you can set your ProtonMail account to send and receive email with addresses such as me@funoccupied.com.

    Can more than one account use my custom domain I direct to ProtonMail MX?
    It is obvious by security reasons that the answer is NO, but I am thinking to force couple of my friends I share email domain with to move to ProtonMail, pay upgraded account and keep our email addresses with our beloved @domain.mail

  2. ProtonMail Support

    At this moment we do not support sub users, which means that you can’t have different login credentials for the addresses you add on your premium account. Also the same domain can’t be used on more than one premium account.

    we own counselingdehoeksteen.nl and cross-fire.nl can we create email adresses with the same security?

    You call this a custom domain and you support only one address? Are you kidding me? And you are only showing this in a small note in the COMMENT section? We just paid you full year for this nonsense! This is unacceptable! How we are suppose to use this now? Having all our users login into one account or what?

  6. ProtonMail Support

    Hi,
    Sorry for the inconvenience. We are planning to implement option to set up different logins and mailboxes in the near future.
    Can you please contact us at contact@protonmail.com?

    Hi there, is the near future of summer 2016 still near? 🙂
    We need multiple addresses with the same custom domain, do you still plan to make this feature available?
    Thank you!

  8. ProtonMail Support

    Multiple custom domain addresses with separate logins are available with the sub-users feature for Professional and Visionary accounts.

  9. Armando

    how do i create multiple users with separate loggins?

  10. ProtonMail Support

    To create sub-users, you will need to have a custom domain set up. Once you set up the custom domain, go to Settings > Addresses/Users and click on the ADD USER button. Please note that sub-users can only have custom domain addresses assigned.

    Hello
    I would like to know several things about Protonmail.
    1°) Is it possible to add informations about contact such as address, phone number, a second or third email address?
    2°) If I put a message from “Inbox” in a “Label setting”, can this message be automatically transferred in this “Label” so that it does not appear in “Inbox”? Or must I for each message (in a second time) “move it to archive”?
    3°) What is a “Custom domain”: what is it for?
    Thank you in advance for your answers.
    Best regards,
    Eric Mallet

  12. ProtonMail Support

    At this moment the contacts have only Name and e-mail address fields, we are working on adding more fields in the future. The Labeled messages show in the Inbox, unless you move them to the Archive, you can do this when you apply a label to the message, by checking the Also Archive checkbox. You can read about custom domains in this article

    If I am using a custom domain connected to a proton mail account, is this equally secure as a protonmail domain would be?
    Specifically, should I be concerned about a security breach through the web/domain host (with whom I have the mail server pointed at Protonmail)?

  14. ProtonMail Support

    Using a custom domain is just as safe as using ProtonMail domain addresses since all communication goes through ProtonMail’s servers and is encrypted using our encryption.

    I’D LIKE TO KNOW THE OUTGOING SMTP SERVER

  16. ProtonMail Support

    Sending using SMTP is only available via the ProtonMail Bridge. https://protonmail.com/bridge/
    Please note that the Bridge is only available for premium accounts.

    To date I’ve only used my protonmail account with username@protonmail.com, however I’m considering using a custom domain email address like someotherusername@custom_domain.com and wish to know if that will interfere with my username@protonmail.com email address. To put this another way, can I use username@protonmail.com AND someotherusername@custom_domain.com ?? I intend hosting a website in due course on custom_domain.com, consequently I’ll need to configure DNS services to point to the host. Presumably protonmail custom domain configuration only requires A / MX configuration ?

  18. ProtonMail Support

    Setting up a custom domain address does not affect your protonmail.com address. ProtonMail only requires MX and TXT records, A is not used for ProtonMail.

  19. Angelhair

    What happens if I create a custom domain email address and then don’t pay the subscription? Do I lose access to that email? Not that I’m planning on that. This is coming from someone who has donated before and just signed up for the service.

  20. ProtonMail Support

    Failing to pay your invoice on time will cause your account to become delinquent with limited access. You can read more about account delinquency here: https://protonmail.com/support/knowledge-base/delinquency/.

    I don’t need a custom domain for my purposes. I just want to add an additional user to this account. I just upgraded to the Professional level and all I really need is two users for the email service. No custom domain – nothing else

  22. ProtonMail Support

    Additional users can only be added using custom domain addresses. ProtonMail domain addresses can only be added as aliases that share the same mailbox to the main ProtonMail account.

    I need to add my domain and it askes me to provide the password!? what password???

  26. ProtonMail Support

    When adding a custom domain to ProtonMail, you will need to enter your current ProtonMail login password.

    If I currently host an email on G Suite, once I add the domain to ProtonMail, will my emails transition over? Will I still able to access them in G Suite? Or, do I lose them?

  28. ProtonMail Support

    Your current messages will not be transferred automatically from Gmail to ProtonMail. At the moment, the only way to move messages from one account to another is to use the ProtonMail Bridge app (https://protonmail.com/bridge/) to set up both accounts in a desktop email client. Once you have both addresses set up in the same email client, you can use drag and drop to move messages from one account to the other.

    I want to switch from a yahoo account to a paid protonMail account.
    Is it easy to 1) import all my contacts into protonmail 2) Import my yahoo folders into protonMail 3) import my “sent mail” from Yahoo. I don’t need details on how to do this, just want to know if it’s easy to do – If so I’m sure I can figure it out. Thanks thanks,
    Vince

    I was looking to register a domain name here. and Protonmail has a link with a suggestion to namecheap.com This company is a straight fraud scam company. that im trying to deal with now and its just a nightmare. they are selling the domain names while their service is not even working and the next day you find out that the domain name you tought you got is still on their web page.Also so many people are having a terrible expirience with them…My poit is why you guys damage your reputation and sugest this scam companies to your clients. namecheap.com is the most terrible company out there.

  32. ProtonMail Support

    Namecheap is just put in as an example. You are free to use any domain registrar you prefer.

  33. MacGyver

    Hi there,

    ERR… From what I understood, YOU (Protonmail) were going to provide me with a domain option ie john@smith.com.
    Am I to assume that now I have paid for premium, I actually need to pay again for yet another email domain?

    Thanks – or not as the case may be lol

  34. ProtonMail Support

    ProtonMail does not offer domain registration services. You will need to purchase a domain name from a third party domain registrar which you can then use in ProtonMail. If you need help with setting up your domain after purchasing it, our support team can assist you: https://protonmail.com/support-form.
