It shows the percentage of emails that failed to be delivered to the recipients, indicating issues with email list quality and delivery effectiveness. By clicking on Activity > Bounced, you will be able to see the detailed bounced report.

Here, we have clicked on Activity > Bounced.

Then, click on View: All. Both hard-bounced and soft-bounced listed here. Using this filter, you can view hard-bounced and soft-bounced leads from your sent campaign.
