Here at Constant Contact, we are an industry leader in email delivery. This is no accident. Our Terms and Conditions are designed to ensure the best possible delivery rate for all of our customers.

That being said, it’s expected (read: absolutely normal) that most email campaigns will have some level of bounces. Knowing the cause and reasons behind these bounces can help you as a marketer to ensure you are mailing to the cleanest, most engaged list that you can. First, I covered Non-Existent and Suspended bounces, then Undeliverable and Blocked bounces; today I will be going over the remaining categories: Mailbox Full, Vacation/Auto-Reply, and Other.
