What if one user is eligible for multiple stages at the same time?

Instances will occur where a user was supposed to get multiple stages, like an anniversary email, an engagement email, and an abandoned cart. In other systems, a marketer would have to run multiple campaigns or would have spent hours building a complex drip campaign with a lot of guesswork as to who should receive what. 

Cortex will recognize each stage a user is eligible for, and then select the one that is most likely to get a conversion. The other stages will be queued up until that user’s next optimal timing window, at which point our models will again make a decision, and start expiring stages that went too long without sending. These thousands of micro-decisions made by our Artificial Intelligence system are what make Cortex so valuable: statistical and predictive sophistication without the marketer having to do the work. Imagine all the time you will save to focus on brand and strategy.
