Your bounce rate is the percentage of email addresses that your campaign could not be delivered to.
Some bounces are a result of the recipient or their mail service marking your campaign as SPAM or complain against it.

Bounce rates are often related to the quality of your subscriber lists. Low bounce rates are a good indication of a healthy, permission-based list with active and engaged subscribers. High bounce rates indicate there may be problems with the way your list has grown, or how it is being managed.
As a guideline, a well maintained, permission-based list should typically see bounce rates of 2-3% or less for each email campaign sent.

A bounce summary is available as part of your standard report and will give you a breakdown of the bounce types that are affecting your campaign.

How we handle bounces
We work hard to keep bounces as low as possible so we can deliver as many of your emails as possible. We constantly monitor the email acceptance rates of our outgoing IP addresses and use sophisticated algorithms to automatically adjust sending rates, as well as giving you the opportunity to control send throttling as part of your campaign set up. We also monitor user behaviour and employ queueing technology to ensure that ISPs are not overloaded.
As mentioned earlier, when an email address appears in the Bounce Summary report it means we are no longer attempting to deliver your campaign to that email address. However, unless it's a hard bounce, we do make repeated attempts to deliver the email for up to 2 days.
Global Suppression list
One of the great advantages of being a part of the e-shot™ system is being able to benefit from our vast experience in sending billions of emails. We are constantly monitoring email behaviour across the platform which ensures that any address found to be invalid or marked as Hard Bounce is automatically suppressed from future sends. By sharing this information and identifying hard bounce email addresses across accounts, you reduce the risk of your sends being blocked by ISPs which will result in better reputation and better deliverability. When you import a new list of addresses, you will benefit from not sending to addresses previously found to be invalid and increase your deliverability.
In short, known bounced email addresses across our accounts are automatically suppressed from your list without affecting your reputation;
