I've just released an improvement to the Customer Grades report in Repeat Customer Insights.
Now every store can signup to have your customer grades emailed to you automatically every week or month as part of the email subscriptions initiative. I'm pushing to get as many of the reports emailable as possible this year so your Shopify metrics are easier to access and use. This is the 6th report that supports email subscriptions and more are on the way.

If you're a customer already, this is already enabled in your account and you can signup for tomorrow's email in the app.
If you haven't tried Repeat Customer Insights yet, it comes with a 14-day free trial so you can see how it helps before paying.

Promote products that create your best customers
When it's time to run a promotion, how do you pick the products to feature? Best sellers are okay but wouldn't it better to promote the products that crate the best customers? Repeat Customer Insights will analyze your product and buyer behavior to show which products and variants lead to the highest quality customers.
