Suppression Lists
To maintain favorable reputations with mailbox providers, our system reviews recipient lists and automatically suppresses email addresses for the following reasons:
-
Hard bounces — When email delivery fails, mailbox providers send bounce code responses. The system categorizes and tracks these bounce codes so that it can suppress email addresses when they fail, such as when a recipient's address is invalid or their account is closed.
-
SPAM complaints — Our email specialists help maintain Feedback Loop (FBL) agreements with mailbox providers that offer FBL programs. With an FBL agreement, a mailbox provider agrees to inform us when a recipient marks a message as unsolicited — such as when they select a "This is SPAM" button or link — so that our system can suppress their email address from future mailings from that sender.
Note: For most Blackbaud products, when a recipient marks an email as SPAM, Blackbaud doesn't suppress their address for other organizations. However, SPAM complaints for messages from Education Management extend to all organizations who use the product.
-
Opt-out links — When a recipient uses a legally required opt-out link in a message to request removal from emails, our system suppresses their address from future mailings specific to their request, such as only for a particular newsletter or all emails from a school.
