Fifteen thousand contacts. Two thousand six hundred who ever open.
Opens and clicks sliding quarter after quarter, or falling off a cliff in a single month, with nothing in the account that explains it and no metric you can trust enough to argue with.
"My email performance randomly fell off a cliff this month." The word doing the work in that sentence is randomly. It almost never is.
You are trying to diagnose a decline using a number that stopped being trustworthy years ago.
Apple Mail Privacy Protection pre-loads images, which registers as an open the recipient never performed. Corporate security scanners click every link in an email to check it is safe. Both inflate your numbers, neither is a human, and the proportion of each shifts over time on its own.
So a 60% open rate sitting next to a 0.5% click rate is a measurement artefact being read as an audience.
“I can't tell what actually changed.”
Three different things produce the same looking chart, and the fix for each is different. Telling them apart is most of the job.
Placement, not interest
If you quietly moved into Promotions or junk, opens fall while the audience is unchanged. That is a deliverability problem wearing an engagement costume, and it gets fixed on a different page.
Fatigue from too many sends, mostly discounts
Send often enough with nothing to say and people stop looking without ever unsubscribing. The list appears intact on the dashboard while functionally shrinking every week.
The list was built from people who never wanted it
A signup incentive that doubled your list handed you thousands of people who wanted ten percent off once. They were never subscribers, and their silence is now dragging down everyone else.
What Gets Done Instead
Measure something real, then act on the segment rather than the average.
Stop reporting on opens
Clicks, placed orders and revenue per recipient survive both Apple and the scanners. The account gets re-based on those, which usually means the first trustworthy number you have seen in a while. It will be lower.
Segment by behaviour, not by opens
Engaged segments defined on opens are circular once opens are partly fake. Rebuilt on clicks and purchases, they stop flattering you and start being useful.
One real re-engagement attempt, then suppression
A genuine last message to the people who have gone quiet, and then they come out of the sending pool. Carrying them forever is what caused the decline.
Send less, to people who want it
Frequency gets set against what the engaged segment tolerates rather than what the calendar says. A smaller number of better sends usually raises revenue while the list size falls.
What This Will Not Get Back
People who left are gone
Re-engagement recovers a small fraction, and realistically that is single digits. The value of the exercise is in what you stop dragging behind you, not in who you win back.
Segmentation will not save mail nobody wants
If every send is a discount, cleaning the list just means fewer people ignoring you more accurately. That is the next page along.
