What is a certification program in email?
Certification programs vouch for sender quality to MBPs. Certified senders meet standards for authentication, list practices, and complaint management. In exchange, participating MBPs may apply lighter filtering to certified mail.
Programs evaluate senders against criteria including: proper authentication setup, low complaint rates, valid list acquisition practices, and compliance monitoring. Ongoing compliance is required; violations result in decertification.
Major programs include: Certified Senders Alliance (CSA) in Europe and Validity's Certification program globally. Benefits vary by MBP participation. Certification provides third-party validation of practices rather than guaranteed inboxing.
