why do email addresses end up on the bounce list?

Why are emails going in the bounce list?

Addresses are placed on our bounce list to prevent rejected emails.  When emails are rejected, it raises our spam score and can result in wide spread filtering.  The most common reason why emails are rejected is due to spam filtering, but it could also be due to many other reasons.

For more information on how to prevent this from happening again in the future, please see the following guide:
