What is panel-based inbox monitoring?

Panel-based monitoring tracks placement using real users who have granted permission to monitor their inboxes.

Unlike seeds, panel members are actual email users with genuine engagement histories. They receive real mail, interact naturally, and have established relationships with senders.

Panel data shows placement in context of real user behavior. It captures how engaged versus disengaged users experience the same sender's messages.

Services like Everest and Return Path historically used panel data to supplement seed testing.
