Unsubscribe Rate

Unsubscribe rate is a key email marketing metric that measures the percentage of recipients who click the unsubscribe link after receiving an email. It is calculated by dividing the number of unsubscribes by the number of emails delivered, then multiplying by 100. A healthy unsubscribe rate for B2B emails typically falls below 0.5%, though this varies by industry and email type.

Tracking unsubscribe rates provides valuable insight into audience satisfaction and content relevance. A sudden spike in unsubscribes often indicates that email frequency is too high, content is not relevant, or the audience was not properly targeted. Consistently high unsubscribe rates can damage sender reputation, leading to deliverability issues that affect all future campaigns.

For B2B sales teams conducting cold outreach, managing unsubscribe rates is especially important. Personalizing messages based on the prospect's industry, role, and pain points also keeps unsubscribe rates low by making each email feel relevant and valuable.
