Two numbers in, one verdict out: your bounce rate against the thresholds that decide whether your next send lands.

Bounce rate is the one metric inbox providers treat as a confession. Engagement can be argued with; a hard bounce means you mailed an address that does not exist, and senders who do that at volume are senders who scraped. Past 2%, filters get skeptical of everything else you send. Our own campaigns run near zero because every lead is verified before send; the same benchmark should be yours.
