How has engagement-based filtering changed email marketing?

Engagement based filtering forced marketers to abandon volume for relevance. Sending to everyone became a liability instead of a growth tactic. Segmentation, lifecycle messaging, and list hygiene became critical.

Marketers now focus on active subscribers, permission based acquisition, and consistent sending habits.

This shift made email more quality driven. It turned the channel from loudspeakers into conversations.

Think of it as moving from dumping crates into the sea to carefully delivering packages to the right ships at the right moment.
