What does Prove the mail mean?

On SpoofCoach, Prove the mail is the second row on At a glance. It’s whether real company mail can carry a quiet prove-it’s-us mark so people have an easier time telling your messages from lookalikes.

Checks out on this row means that mark looks set up and readable. Needs a look means it isn’t clear yet — so don’t treat that piece as done until you take the one next step on screen.

Prove the mail is not a promise that every fake email disappears. It’s whether honest mail from your domain can show it’s really yours.
