Email Bounce Rates

Email bounce rate refers to the percentage of emails that cannot be successfully delivered to recipients’ inboxes. When you send out an email campaign, some emails may "bounce back," meaning they’re returned because the address is invalid, full, or blocked. A high bounce rate indicates issues with your email list or delivery process, which can harm your sender reputation and reduce campaign effectiveness. Monitoring bounce rates helps improve email deliverability by identifying and removing invalid addresses, ensuring your messages reach the intended audience efficiently and reliably.
