Unsubscribe Rate Calculator
Calculate your email unsubscribe rate. Healthy benchmark is below 0.5%. Free browser-based calculator.
How Unsubscribe Rate Calculator Works
Unsubscribe Rate = (Unsubscribes ÷ Emails Delivered) × 100. Google and Yahoo's 2024 bulk sender requirements begin penalising deliverability above 0.3%. Unsubscribes are the proactive metric to monitor; high unsubscribe rates often precede spam complaints. A sustained 0.5% unsubscribe rate signals content-offer misalignment or send frequency problems and warrants immediate investigation.

Frequently Asked Questions
What is email unsubscribe rate?
Unsubscribe rate measures the percentage of delivered emails that result in an unsubscribe. Formula: (Unsubscribes ÷ Delivered) × 100. In February 2024, Google and Yahoo introduced bulk sender requirements that treat spam complaint rates above 0.3% as a deliverability trigger — unsubscribes are the better metric to monitor proactively.
What is a good unsubscribe rate?
Below 0.5% is the general benchmark. Google's spam threshold of 0.3% for complaints is separate but related — high unsubscribes often precede high spam complaints. A sudden spike is more concerning than a consistently slightly-elevated rate.
High unsubscribes — what to do?
Identify which segment triggered the spike (new subscribers, a specific campaign, a frequency increase). Check whether the email content matched the subscribe promise. Consider a re-engagement sequence for inactive subscribers instead of sending to the full list.
