How do engagement-based suppressions improve placement?

Engagement-based suppression removes chronically disengaged addresses from active sending:

Improved metrics: Sending only to engaged users raises open and click rates.

Positive signal concentration: More of your sends generate good engagement signals.

Reputation lift: Higher engagement rates improve sender reputation scores.

Better placement: Good reputation earns better inbox placement.

Counterintuitively, sending to fewer people can improve results. Quality of engagement matters more than quantity of sends.

Trade with merchants who want your goods. Stop delivering to warehouses that never open.
