Understanding Unsubscribe Rate
What is Unsubscribe Rate?
The Unsubscribe Rate is the percentage of email recipients who opt-out from your mailing list after receiving an email. While no one likes to lose a subscriber, this metric is an incredibly valuable and direct form of feedback from your audience about the relevance and frequency of your content.
How to Calculate Unsubscribe Rate
The formula for calculating the unsubscribe rate is:
This calculator uses the number of successfully delivered emails (not total sent) to give you the most accurate measure of audience disengagement.
Why a Low Unsubscribe Rate is Important
A low unsubscribe rate is a strong indicator of a healthy and engaged email list. It suggests that:
- Your content is relevant: You are sending messages that your audience expects and finds valuable.
- You have a healthy sending frequency: You aren’t overwhelming your subscribers’ inboxes.
- Your list is well-segmented: You are sending targeted content to the right groups of people.
- You are meeting expectations: The content you send matches what subscribers signed up for.
While a small number of unsubscribes is normal and even healthy for list hygiene, a sudden spike can be an early warning sign that your email strategy needs adjustment. A good benchmark to aim for is an unsubscribe rate below 0.5%.
