Where can I find my master list of customers?
You can find all of the customers who have engaged with your site in the Profiles tab on your Klaviyo account.
Have you tried sending to a segment of engaged customers? In a three month period, Klaviyo looked at 2.5 billion emails (that’s billion, with a B) and found segmented emails led to 3 times greater increase in revenue per email recipient and 50% fewer unsubscribes. Want to give it a try? Klaviyo has a handful of built-in segments, but you can find inspiration in the segmentation guide.
