How do I use a custom domain?

If you have a paid Proton Mail plan, you can use a custom domain to send and receive emails (for example, using the email address [e-mail]). The number of custom domains you can use depends on your Proton Mail plan.

You can purchase custom domains from third-party registrars, such as GoDaddy, Cloudflare, or Namecheap. To use a custom domain with your Proton Mail account:

• 1. Add your domain to your Proton Mail account
• 2. Verify your domain so that Proton knows it is genuinely yours
• 3. Configure your domain registrar’s DNS records so that Proton Mail handles the emails sent and received using that domain

Additional steps are required if you have a Proton for Business plan and wish to add users to your organization so that they can use your custom domain.
