Unsubscribe rates show how many people choose to leave your email list after receiving your messages. This number is important because it tells you if your content still matches what people expect. When many people unsubscribe, it may mean your emails are too frequent, not useful, or not clear. A small number is normal, but a steady rise is a warning sign. Watching this rate helps you adjust your topics, timing, and tone so your list stays active and healthy. What do you think is an acceptable unsubscribe rate?
