Customer Segments for A/B Testing Shopify Emails

Topic summary

Main issue: How to split a Shopify email subscriber list into two distinct segments for A/B testing without manual effort.

  • Context: A/B testing compares two email variations to measure performance. Segmentation is grouping subscribers; Shopify “Tags” are labels added to customers to build segments.
  • Current approach suggested by Shopify support: Manually add a Tag to half of the ~40,000 subscribers, then target each segment separately.
  • Problem: Manual tagging at this scale is time-consuming and impractical.

Is there an easy way to split our entire list of subscribed customers and split them into 2 unique segments/lists for A/B Testing Shopify Emails? I reached out Shopify support and they said we can add a Tag to half of our subscriber list, but we have nearly 40K subscribers, so this would take a long time. Is there an easier way to accomplish this?

Sorry that I’m piggy-backing, but did you find a solution to this? I have the same question…
