One of the original features of Repeat Customer Insights is the Order Sequencing reports (then called the Customer Purchase Latency report).
Today's update now adds email subscriptions to that report. Now you can have those reports emailed automatically every week or month. I've found it useful to compare how the Average Order Value and Repeat Purchase Rate change over-time.
All Repeat Customer Insights accounts with access to the Order Sequencing can setup these email subscriptions now in the app.
If you haven't tried the app yet, it comes with a 14-day free trial so you can see how it helps before paying.
Track down which customer cohorts perform the best
Different groups of people behave differently. Repeat Customer Insights creates cohort groups for you automatically to see how your customers change over time and spot new behavior trends.
