The percentage of recipients who opt out of future emails. Healthy lists see 0.2-0.5% per send.

Why It Matters

Unsubscribes are actually healthier than spam complaints—people self-selecting out keeps your list engaged. A rate of 0.2-0.5% is normal. Higher rates indicate content/frequency problems. Paradoxically, making unsubscribe easy can improve overall deliverability by reducing complaints.

Practical Example

Scenario

A fitness apparel brand sends a weekly newsletter to 25,000 subscribers. Each week, about 75 people unsubscribe.

Calculation

75 ÷ 25,000 × 100 = 0.3% unsubscribe rate

Result

At 0.3% per send, they're within healthy range. Over a year, they'll lose ~3,900 subscribers to unsubscribes, but spam complaints stay near zero and engagement remains strong.

Pro Tips

  • 1Offer preference management before full unsubscribe (frequency reduction, topic selection)
  • 2Track unsubscribe rate by campaign to identify content that drives people away
  • 3A small unsubscribe spike after promotional periods is normal—people opting out after sales
  • 4Use exit surveys to understand why people unsubscribe and address systemic issues

Common Mistakes to Avoid

Panicking over normal unsubscribe rates and reducing email frequency too drastically
Making unsubscribe difficult, which increases spam complaints instead
Not segmenting unsubscribe data by subscriber tenure (new vs long-term)
