# What is an email bounce rate?

Email bounce rate is the percentage of emails that could not be delivered to the recipient’s inbox and were returned to the sender.

A high bounce rate can negatively affect your email deliverability and sender reputation. If the bounce rate remains too high, your account may be **temporarily restricted or blocked** to protect your sender reputation and maintain email delivery quality.

To maintain a healthy bounce rate, regularly clean your contact list and remove invalid or inactive email addresses.
