Definition of an Email Bounce
The definition of what an email bounce means.
A bounced email is one that is sent out but never reaches it's receipt and is therefore sent back. This can be because of a number of reasons. Most commonly the reason is that the email address is not correct or doesn't exist. But sometimes if the computer server for which the email is sending to is busy or not responding this can cause the email to "bounce back".
In our marketing stats email we count any email that came back marked undeliverable as a bounced email. We also clean your email list for you by automatically remove email addresses that bounce. Keeping a clean mailing list is an essential part of making sure your emails don't end up in spam folders or blocked all together.
A bounced email is similar to the post office putting return to sender on a piece of mail because an address doesn't exist.
