Guide to Trigger Event Splits in Automation Flows

Automation flows are the perfect way to create and send multi-stage communications triggered by a certain event (e.g., subscribing to texts, placing an order, etc.). With Flow Builder, you can schedule individual messages, limit the frequency of how often a subscriber can enter your flow, and take advantage of trigger event splits. 

Using trigger event splits in your flows allows you to easily visualize and build unique pathways determined by subscriber actions.

How Trigger Event Splits Benefit You

  • Build flows more efficiently by creating one automation flow with multiple branches that vary based on trigger event properties.
  • Increase conversions when you craft automation flows that are more targeted and personalized to susbcribers' buying experience.

Post Purchase Example

With trigger event splits, you can tailor your subscribers' post purchase journey to their shopping experience. In the example below, we'll create a three branches - one educating customers on their product, one cross-selling a complementary product, and one reminding subscribers to restock - all in a single automation.

Product Added to Cart Example

You can use trigger event splits in order to make your messaging more personalized to your subscribers' journey. In the example below, we'll create two branches. One branch targets subscribers that added less than $50 worth of products to their cart and the other branch targets subscribers that added more than $50 to their cart. Each branch contains a unique offer.
