In a study I did last year, 97% of people don't unsubscribe if they don't want your emails; they will just ignore you.
When someone unsubscribes you think:
"Was it the subject line? The content or timing? Should we have sent this to them at all?"
But most of the time, it has almost nothing to do with you
Here's what you need to know:
1. The majority of disengaged subscribers never leave. They delete, stop opening and damage your deliverability without ever clicking unsubscribe.
The people who do unsubscribe are giving you a gift
2. By the time someone unsubscribes, the decision was made weeks or months earlier. The accumulation of irrelevance, no interest, overwhelm, misaligned expectations, and inbox friction built up long before that final email arrived.
Analysing the email that caused the unsubscribe is almost always the wrong question
3. Your unsubscribe rate is being shaped by other people's emails
Inbox saturation like Black Friday, Mother's Day, and January, drives mass unsubscribes that have nothing to do with your content. You happened to land at the wrong moment.
4. "Too many emails" is rarely about your frequency.
It's about perceived value vs frequency. If every email earns its place, subscribers will tolerate a high cadence. The moment the value drops below the send rate, the inbox math tips.
The full piece covers the tolerance model, predictive coding, how to diagnose a spike, and a practical response framework for all of it.
