How does AI-driven personalization affect deliverability?

AI driven personalization affects deliverability by creating different filtering experiences for different users. Gmail's priority inbox and relevance filtering personalize which messages surface prominently based on individual engagement history and preferences.

This personalization means the same message might reach one user's primary inbox while appearing lower in another user's Promotions tab based on their different interaction patterns with the sender. Universal inbox placement no longer exists; placement varies per recipient.

For senders, personalization increases the importance of engagement. Users who consistently interact positively with your emails see better placement. Users who ignore your messages experience deprioritization. Maintaining engagement across your subscriber base becomes critical for consistent deliverability.
