Email behavior turns opens, clicks, and engagement recency into segments that build themselves. Instead of pulling static lists after a campaign, Smart Segments watches how each contact actually responds to email and keeps those groups current.

For venues running regular sends, this means you can reach the people who open and click without combing through reports first, and see who has gone quiet before they churn. The segment updates as behavior changes, so your next send starts with the right audience instead of a guess.
