How can inbox metrics predict reputation decay?

Early warning signals of reputation decay:

Engagement decline: Falling open and click rates, especially at specific providers. Often precedes reputation problems.

Complaint uptick: Rising spam reports indicate growing recipient dissatisfaction.

Postmaster score drops: Declining reputation ratings before placement fully collapses.

Seed test degradation: Increasing spam folder rates in routine testing.

Bounce pattern changes: New types of blocks or deferrals appearing.

These signals appear before reputation damage becomes severe. Act on early warnings.

Storm clouds gather before the hurricane hits. Read the signs and adjust course early.
