FAQ

What does pct= mean?+

Percentage of messages the policy applies to, p=quarantine pct=10 means only 10% of failing messages get quarantined. Useful for gradual rollout.

Nate built Outsolvi after watching every email-tracking tool he had ever used lie to him about opens. Outsolvi grades every open as a person or a machine, in Outlook and Gmail, so the number on the dashboard is one a rep can actually act on.
