Email Validation Rule

We send the email address of the Pardot Prospect and we receive a numeric "Quality Score" [between 0 and 1]
If the Prospect's quality score is below 50% (0.5), we consider it as potential spam.

PRO TIP: You can adjust the default threshold of 0.5 from the Email Validator Setup tab, using the slider in the Abstract card:
