The percentage of emails that weren't successfully delivered to your recipients’ inboxes. We calculate this number by taking the number of hard and soft bounces divided by the total number of emails sent.
Why it is important
Monitoring Email Bounce rate is essential for maintaining a clean email list and preserving sender reputation. A high bounce rate may lead to deliverability issues, making this metric crucial for identifying and resolving potential problems.
It guides decisions on list management and content optimization to enhance overall email campaign success.
Formula
(Bounces / Emails sent) * 100
Calculation example
If you sent 1,000 emails and had 50 bounces (combination of hard and soft bounces), the Email Bounce Rate would be (50 / 1,000) * 100 = 5%
