By default the CNAME records Simplesat generates will be:
sim._domainkey.example.comsim2._domainkey.example.com
These records are automatically generated by our email provider, SendGrid. Companies who already use SendGrid for another service might need different records.
If you need this, please send the Simplesat team a message that includes the domain you're looking to authenticate and we'll generate them for you. 👍
