What are the first signs of placement decline?

Early warning signs of placement decline:

Open rate drops: Sudden decrease in opens, especially at specific providers, often indicates spam placement.

Click rate decline: Even with stable opens, falling clicks may indicate engagement problems.

Complaint increase: Rising spam reports in FBL data or Postmaster Tools.

Reputation score drop: Gmail Postmaster or SNDS showing declining reputation.

Seed test degradation: More seeds landing in spam on routine tests.

Catch these early. Small problems are easier to fix than major reputation damage.

Watch for subtle course drift before you are far off track.
