Genlook is built directly on top of Shopify’s native customer data model. Whenever a shopper interacts with the virtual try-on widget, Genlook saves their activity straight to their Shopify customer profile. Because of this, any tool you already use that syncs with Shopify customers—like Klaviyo, Omnisend, Mailchimp, or Meta/Google Ads—can instantly leverage this try-on data without requiring any additional setup or custom integrations.

​
The foundation: your Shopify customer segment

When you install the app, Genlook automatically creates a new customer segment in Shopify called “Virtual Try-On Users by Genlook”. You’ll find it in your Shopify admin under Customers → Segments. It uses a simple query: 
customer_tags CONTAINS 'genlook-user'
Any shopper who uses the try-on feature while logged in, or who provides their email through the widget, gets tagged with genlook-user and is automatically added to this segment.
If a shopper tries on an item anonymously (they aren’t logged in and haven’t provided an email), they won’t be added to the segment. We wait until they identify themselves before we attach activity to a customer profile.

​
How Genlook updates customer profiles

Along with the general genlook-user tag, Genlook enriches each customer’s profile with their specific try-on history:

Product-specific tags

We add a specific tag for each variant a customer tries on, formatted as genlook-try-{productId}-{variantId}. This is perfect for creating highly targeted segments (like “customers who tried on the leather jacket”).

Tried-on products metafield

We store a list.product_reference metafield ($app.genlook_tried_on_products) that keeps a running list of every product a customer has tried. These appear natively as clickable product links right in the Shopify admin.
This data stays in sync automatically:
  • Instantly whenever a logged-in shopper tries something on.
  • Retroactively when an anonymous visitor identifies themselves (by logging in or submitting an email). As soon as we know who they are, we backfill their entire previous try-on history to their Shopify profile.

Connect with your favorite tools

Since Genlook writes directly to Shopify, any integration that reads your Shopify customer data will automatically pick up these insights. Here are a few ways merchants use this data:
  • Email & SMS (Klaviyo, Omnisend, Mailchimp): Sync the “Virtual Try-On Users by Genlook” segment to create a dedicated list, or use product-specific tags to trigger personalized follow-up flows. Check out our Klaviyo guide to see this in action.
  • Ad Audiences (Meta, Google, TikTok): Export your try-on segment as a custom audience to retarget high-intent shoppers, or use it to build powerful lookalike audiences.
  • Reviews & Loyalty (Yotpo, Smile, LoyaltyLion): Use try-on tags to trigger targeted review requests or reward customers with loyalty points for trying on new collections.
  • Analytics (Triple Whale, Lifetimely): Combine try-on tags and metafields with your order data to measure how virtual try-on drives conversions.
