Experts and marketers generally agree that seed lists offer a limited and potentially misleading view of email deliverability. While they can provide directional insights and help identify major issues, the increasing personalization of inbox placement decisions by mailbox providers, coupled with evolving filtering algorithms, makes seed list results less representative of real-world email delivery. Factors like engagement history, IP reputation, and content all influence seed list accuracy. A combination of methods, including feedback loops, authentication protocols, real-world testing, and monitoring sender reputation, is recommended for a comprehensive understanding of deliverability.
