Why do people unsubscribe?

People don't unsubscribe because they hate you. They unsubscribe because something shifted. Either your emails changed, their situation changed, or the expectation was never quite right from the start. Knowing which one is happening tells you whether you have a problem to fix or just healthy list churn.

Reasons that are on you (and fixable)

Too much email. The most common reason. If someone signed up for a weekly roundup and you're sending daily, they'll leave. Send frequency is easy to underestimate, and expectations set at signup don't always hold as volume scales.

Content that doesn't match the promise. Someone signed up for educational content and you started blending in promotions. Or they joined for one product line and now you're emailing about another. The expectation gap is fast and unforgiving.

No relevance to where they are now. Same message to everyone, no matter how long they've been on your list or what they've done. When subscribers feel like they're getting mass blasts with nothing tailored to them, they tune out first and unsubscribe when they get around to it.

Reasons that are fine

They got what they needed. Someone signed up to solve a specific problem, solved it, and moved on. This is a healthy unsubscribe. Not every subscriber is supposed to stay forever.

Their situation changed. Job change, company pivot, moved on from the topic. You didn't do anything wrong. The relationship ran its course.

The pattern that actually matters

A stable, low unsubscribe rate with occasional spikes after specific sends is normal. A steady upward trend over 60 to 90 days means something changed in how you're sending or who you're reaching. Look at what shifted in that window: new campaign type, new list source, different frequency, different content direction. One of those usually explains it.

Still if you're seeing a trend and can't pin the cause, the SOS hotline is free.
