Bounce rate is the percentage of sent emails that are not successfully delivered to recipients’ inboxes.
Definition and examples
In email marketing, bounce rate is the percentage of sent emails that are not successfully delivered to the recipient’s inbox. This metric is a health indicator for your email campaigns, pointing to potential issues in your email list and sending practices. A high bounce rate can damage your sender reputation, impede your email deliverability, and ultimately hurt your campaign’s success. Understanding and managing bounce rates is crucial for maintaining effective email marketing campaigns.
Why it matters
It matters because bounces are an early warning sign for list quality and deliverability problems. If bounce rate climbs, it usually means the audience or sending process needs attention quickly.
Types of email bounces
Non-existent email addresses (typos, fake emails). Invalid domain names. Deactivated email accounts. Email addresses that never existed.
Common mistakes
A common mistake is reading the number in isolation. It becomes much more useful when you compare it over time, by segment, and against the next step in the funnel.
