What is an Unsubscribe Rate?
The percentage of email recipients who opt out of your mailing list.
How Unsubscribe Rate Works
Unsubscribe rate measures the percentage of email recipients who click the unsubscribe link to remove themselves from your list. It's calculated by dividing unsubscribes by delivered emails. A healthy unsubscribe rate is typically under 0.5% per campaign.
Some unsubscribes are natural and healthy—not everyone in your audience will remain interested forever, and people who unsubscribe are doing you a favor by self-selecting out rather than marking you as spam. However, elevated unsubscribe rates signal problems: content that doesn't match expectations, too-frequent sending, irrelevant messaging, or list quality issues. Always make unsubscribing easy and prominent—hiding the link increases spam complaints, which are far more damaging than unsubscribes.

Why is Unsubscribe Rate important?
Unsubscribe rate is a direct feedback signal from your audience about content relevance and sending frequency. While losing subscribers feels negative, it's far better than the alternative—spam complaints that damage deliverability for your entire list. Monitoring unsubscribe rate trends by campaign type reveals what content resonates and what drives people away.
How do you calculate Unsubscribe Rate?
Unsubscribe Rate = (Unsubscribes ÷ Emails Delivered) × 100. For example, if you delivered 50,000 emails and 125 people unsubscribed, your unsubscribe rate is (125 ÷ 50,000) × 100 = 0.25%.
