When billions of emails are sent across the world every day, it becomes important to distinguish between senders who are trustworthy and those who are less so.
When it says “Certified by Rule” or “Sent from Rule” in the footer, the recipient can click on it and be directed to Rule.se.
A recipient who is unsure whether the email comes from a reliable provider will then feel reassured, and can – if they wish – choose to unsubscribe from future emails, instead of impulsively clicking the spam button.
Having Rule as the provider in the footer therefore serves as a mark of quality.
