- Short answer
- Live — Shopify adds and removes members automatically; only the count on the segments index lags until you open the segment or an app uses it.
- What lags
- The count on the segments index — Shopify refreshes it when you open the segment or an app uses it.
- How stale is it
- Hovering over the count tells you when Shopify last updated it.
- Autopilot exception
- Campaign Autopilot (early access) picks the audience for the emails it creates; you can't change it.
- As of
- Three Shopify Help Center pages on segments and Autopilot, read September 2, 2026.
Does a Shopify customer segment update itself after you create it?
It does. Shopify calls segments "dynamic, rule-based customer lists that let you group together customers who have similar characteristics," and its overview page ties that to the moment of creation: "After you create a customer segment, customers are automatically added or removed to the segment list based on whether they meet the segment criteria." Its page on managing segments states each direction on its own — a new customer who matches is "automatically included", while an existing one who stops matching is "automatically removed".
Why does the number next to your segment look out of date?
Because live membership and a live number are not the same thing.
The count on the segments index is updated when you view the segment by going to the segment details page or when an app, such as Shopify Messaging, uses the segment.
That lag belongs to the count column, not to who is in the segment. To see how stale a figure is, hover over the count on the segments index and Shopify shows when it was last updated.
Do you need to refresh a segment before you send a campaign?
Membership needs nothing from you. If it is the count you want to trust, open the segment details page first. Which groups deserve a campaign is a separate question, answered in our guide to RFM segmentation.
One kind of send takes the audience out of your hands entirely. Campaign Autopilot "is in early access and is available only to certain merchants", and of the emails it creates, Shopify says: "You can't change the target audience. Autopilot selects the segment to maximize results."
