These are some of the most common questions our clients ask us about using the system and email marketing in general.

- Why are replies from previous campaigns getting mixed up with a recent campaign?
- What is a soft bounce ?
- What is a hard bounce ?
A hard bounce is an email message that has been returned to the sender because it either never existed or doesn't exist anymore. It is permanently undeliverable. Causes include invalid addresses (domain name doesn't exist, typos, username doesn't exist, etc.) or the email recipient's mail server has blocked your server. Examples include (reason: 550 user unknown), connection refused by <domain> and (reason: 550 host unknown). Servers will also interpret bounces differently, meaning a soft bounce on one server may be classified as a hard bounce on another. Also, the exact error message returned may be different between servers. One may return "user unknown" while another might say "invalid recipient" or "mailbox unavailable".
