If you purchased a custom domain (such as yourdomain.com), you can use it to send and receive email with your proton mail (new window) account (for example, using the email address yourname@yourdomain.com ).
To do this, you must have a paid proton mail plan (new window). The number of custom domains you can use with Proton Mail depends on your plan.
- proton mail plus: 1 custom domain
- unlimited proton: 3 custom domains
- proton visionary (legacy users only): 10 custom domains
- proton mail essentials: 3 custom domains
- proton business : 10 custom domains (default with option to add more)
The procedure to configure your custom domain to be used by your proton email account is as follows:
- add your domain to your proton email account.
- verify your domain so proton knows it’s really yours.
- create new users and add members of the computer to your account.
- Set up your domain registrar’s DNS records so that proton mail handles emails sent and received using that domain.
- Set up your email address.
add your domain
1. In your browser, log in to your proton mail account and select settings → go to settings → proton mail → domain names → add domain.
2. enter your domain name and click next. You may be prompted to re-enter your proton password for security reasons.
verify your domain
The first thing you need to do after adding a custom domain name is to show proton mail that you control this domain. You can do this by adding a txt record with a unique code that Proton Mail has generated to your domain’s DNS records in your registrar’s domain management portal.
proton mail servers will search all txt records for your domain and see if any match the verification code. if we find a match, the verification is successful and you can continue with the next steps.
once you click next, you will be taken to the verify tab. You can also access it from settings → go to settings → proton mail → domain names → domain by clicking on the actions button→ review and selecting the verify tab.
In the verify tab, your hostname (@) and the verification log txt are appear to the right of your newly added domain.
click the small copy icon to the left of the txt verification record to copy it to your clipboard. you can then paste it into your registrar’s domain management portal.
wait a few minutes, then click next to activate a dns check by our servers. if successful, you can now proceed to the next steps. if you were unsuccessful, don’t worry; our servers may still be reading old cached dns records.
note: If your dns login page doesn’t allow you to add @ as the hostname, try leaving this field blank when entering your dns verification information. proton mail. some hosting providers do not provide a “host/name” field. if this is the case, provide all other information and ignore the “host/name” in the verification step.
wait an hour and return to the same page to see if it was successful. this can take up to a day, depending on your ttl settings. If you are still unsuccessful and have double-checked that your dns matches the code in the setup wizard, please contact our customer support (new window) for assistance.
After the first verification, our servers will periodically check your domain’s dns records and update the status of your domain. This is crucial as it helps us maintain the correct verification code in your domain’s DNS settings and quickly troubleshoot any DNS issues. After setting up your entire domain, if we detect any missing dns records, such as the verification record, we will notify you for one week before disabling your domain and addresses.
create an organization
Now that you have a domain, if you’re subscribed to a plan that supports multiple users, such as a proton visionary (legacy users only) or a proton for business plan, you can create an organization (new window) and add users to it (new window). if you are not subscribed to proton visionary or proton for business plan, you should skip this step and go directly to activating your domain.
share login information with your team members
Before you change your mx records, we recommend that you let your team members know about the upcoming change. after changing the mx records, the emails will be sent to your proton mail inboxes instead of your old inboxes.
activate your domain
once your domain is verified, click next to go to the mx tab (or come back to this page later and just go directly to the mx tab). The mail exchanger (MX) record is vital to how email works: it tells the internet which server(s) should receive email from your domain.
If you are setting up a new domain, go ahead and add the specified mx records in your domain name registrar’s control panel.
if your domain currently has existing mailboxes, we recommend adding all used email addresses before changing your mx records to proton mail to ensure a smooth transition. we describe how to do this below.
This will help you avoid interruptions in your email delivery because proton mail will only accept mail for the addresses you have added. mail.protonmail.ch points to proton mail’s mail servers, so once you’ve made this change, you’re telling the internet to send email for your domain to your proton account mail.
If you have mx records for multiple services, email will be delivered to the service with the highest priority (lowest value). if you have other mx records, you should delete them or make sure that the priority of mail.protonmail.ch is a smaller number (higher priority) than the other mx records.
again, mx changes may take up to a day to propagate and email may still go to your old mx during this transition. once we detect that the top mx record for your domain points to proton mail, the mx tab will show a green tick icon.
set your addresses
If you are changing an existing domain to send emails to your proton mail inbox, you must set up all existing email addresses before completing mx records (as described above) .
select the address tab →add address.
this will take you to the organization section of your proton mail accounts page. Click add address to create a proton mail email address using your custom domain. if you have more than one custom domain, you can select which one to use from the dropdown list.
You will be asked what level of encryption you want to use for the keys that will be generated for your account. the default is state of the art, but you can also choose compatibility. click save address when you’re done. you may need to re-enter your password.
Now that you’ve completed all the necessary steps to set up your custom domain, we can explore anti-phishing methods to protect your email delivery and prevent email spoofing.
