How to use a custom domain with Proton Mail

You can create email addresses with your own domain name in Proton Mail, such as yourname@yourdomain.com, to send and receive messages.

To use a custom domain with Proton Mail, you must have both:

A custom domain, such as yourdomain.com: You can purchase one from a domain name registrar.
A Proton subscription plan that supports custom domains: If you don’t have one, select a plan.

The next steps are to connect your custom domain to your Proton Mail account, and then add users and email addresses. Here’s how:

Step 1: Create your organization
Step 2: Connect and verify your domain
Step 3: Create new users and addresses
Note to organizations migrating multiple users to Proton Mail: Please create corresponding email addresses on Proton Mail before changing the MX records. This can prevent losing emails during the migration.
Step 4: Update MX records
Step 5: Configure MX, SPF, DKIM, and DMARC records
