The really useful part about having Repeat Customer Insights email me the reports is that it makes it really easy to stay up on how the business is operating.
For a couple of years now I've been using the weekly Monday Morning Metrics to monitor sales last week from new and repeat customers (or in my case, new trial conversions and repeat customers). It only takes a minute to scan through the email, compare the performance to what I have in my head, and get the temperature of how things are going.
The usability of having that just show up in my inbox has been a time-saver.
With the new focus report emails, I have new metrics I can start to monitor.
No matter how fancy or flashy reports are, they are worthless if you don't look at them.
Having them show up automatically in email makes them easy to find.
That makes them easy to act on.
