List Hygiene / Bounce Management
List hygiene refers to the maintenance of your email list. An email list is considered clean when it is free from dead and unresponsive addresses. MyNewsletterBuilder (MNB) helps keep your email lists clean by automatically removing subscribers whose emails addresses report a hard bounce while automatically trying to resend for soft bounces; however, you should manually delete any contacts that continuously soft bounce. A hygienic email list will generate a higher open rate.
