Granular audience targeting without SQL queries
Send the right message to the right segment. Automatically group contacts into dynamic segments that update in real time as user behavior and attributes change.

What is Mailofly Dynamic Audience Segmentation?
Mailofly Contact Segmentation evaluates contact membership dynamically using real-time attribute filters and behavioral history (e.g. opened within 30 days, clicked a URL, plan tier). Segments update continuously without manual list exports or SQL scripts.
