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

    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 are working on adding this feature in the future.

    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?

    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?

    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

    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.
