  • Proton recommends p=quarantine for most domains. Move to it once SPF and DKIM pass.

  2. Enter a Host only if your provider gives one, and paste the value in Answer.
  3. Click Add Record.

Check your setup

We only read public DNS records. Nothing is stored.

Common mistakes with Proton Mail on Name.com

Adding only one DKIM record

Proton uses three DKIM CNAMEs (protonmail, protonmail2, protonmail3). Add all three, matching the values in your setup wizard exactly.

Name.com: Never leave a CNAME Host blank

A CNAME without a Host can overwrite other records such as MX and break email.
