Buy Again is a unique stage in your post-purchase email campaign. It's an opportunity to send a targeted message at a calculated interval to drive repeat purchases of specific items.
The Buy Again stage is powered by the replenish_interval variable. Replenish_interval is the number of days after a purchase when Cortex will send your Buy Again email. For example, if you sell small and large vitamin bottles, the small bottle might have a replenishment interval close to 30 days, while the large bottle would be closer to 180 days.
How is the Replenish Interval number set?
Cortex monitors your customers' behavior and will set replenishment intervals automatically for items which are purchased more than once by customers. When possible, replenishment intervals will be customized based on the user's individual buying patterns, or on an observed pattern from similar users.
How can I set the Replenish Interval myself?
