How can I segment unsubscribers in Shopify Email?

Topic summary

A user wants to migrate from Klaviyo to Shopify Email but needs to segment customers who opt out of specific event-based campaigns (like Father’s Day or Mother’s Day emails).

Current Challenge:

  • Successfully created an unsubscribe confirmation page
  • Cannot find a way to automatically group these event-specific unsubscribers into a segment within Shopify Email
  • Unclear how to configure the unsubscribe button to trigger segment creation

Status: The question remains unanswered, with two additional users confirming they face the same limitation and have been unable to find a solution.

Same question from me. Did this ever get answered?
