02Questions about this tool

What is SPF?

A TXT record that lists the servers allowed to send email for your domain. Without it, Gmail is likely to mark your mail as spam.

What is DMARC?

A policy record that tells receivers what to do when SPF or DKIM fails. Start with p=none to monitor, then move to quarantine.

What is a DKIM selector?

DKIM keys are stored under a name called a selector, like default._domainkey. cPanel uses default. Google Workspace uses google.
