Digital marketing term
Unsubscribe Rate
Unsubscribe Rate is the metric that shows the share of recipients who unsubscribed from a list after receiving an email campaign, relative to the total number of recipients it was sent to.
Detailed explanation
A rise in this rate generally signals that content doesn't match expectations, that send frequency is too high, or that segmentation is insufficient; if it stays elevated consistently, it can damage brand reputation and sender score.
Even when this rate is low, it shouldn't be ignored, because keeping list quality high ensures the remaining recipients stay more relevant and engaged, which has a positive effect on deliverability over the long run.
Proper segmentation, sending content based on interest, and adjusting send frequency to recipient preference are among the most effective ways to lower this rate.
