Falling engagement is both a symptom and a cause
Gmail, Microsoft, and Yahoo score you per recipient based on how people interact with your mail. When engagement drops, they move more of your sends to Spam or Promotions, which lowers engagement further, which tightens the filtering.
Opens slid for months, then clicks followed.
The classic filtering curve, not a creative one.

Gmail dropped, other providers didn’t.
Provider-specific filtering.
Your list grew, but revenue per send fell.
The new volume is diluting, not compounding.

Frequency went up, totals stayed flat.
Spending reputation to stand still.
Open rate looks fine, clicks don’t
Automated opens are masking the decline.

Re-engagement campaigns underperform
Already filtered, so the win-back never arrives.
Any of these could be quietly killing your deliverability
Each of these causes points to the same outcome: the inbox stops trusting you, and your campaigns stop performing. The tricky part: several can be true at once, and the wrong fix makes it worse. That’s why a proper diagnosis with a relevant implementation order matters.
01
No sunset policy or segmentation
Contacts dormant for 6–12 months still get every send; your best subscribers subsidize your worst.
02
Frequency outrunning interest
More campaigns increase fatigue, deletes, and complaints faster than they increase revenue.
03
Mail landing in Spam or Promotions
Opens can’t happen where nobody looks; placement problems look like engagement problems.
04
Weak acquisition, mismatched promise
Contests and bought lists bring people who never wanted this; those who expected something else just stop.
05
Automated opens hide the decline
Machine-fired pixels keep the dashboard green while human attention drops.
06
Broken or hidden unsubscribe
Hard opt-out turns unsubscribes into spam complaints. One-click is mandatory since February 2024.
07
Authentication or infrastructure gaps
Missing DKIM alignment or an unwarmed domain suppresses placement before engagement is measured.
08
Re-engagement at full volume
A win-back to a large, dormant segment consolidates all negative signals into a single send.
09
No one-click unsubscribe
Since 2024, it’s mandatory — miss it and Gmail & Yahoo throttle you outright.
10
Domain spoofed or compromised
Abuse sent under your name destroys the reputation you spent years building.
