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.
