You want a list of Shopify stores that have Klaviyo installed so you can pitch them a complementary tool (postcards, SMS, retention, CRO).
Klaviyo runs on a large slice of Shopify Plus and Shopify standard stores. If you sell a complementary tool (postcards, SMS, loyalty, retention, CRO, paid social, attribution), the best-fit prospect is a store already paying Klaviyo for email. They've made the call that retention matters, they're spending real money on a CRM, and they're hungry for the next layer.
The hard part is finding them. Klaviyo doesn't publish a customer list, and the existing technographic tools either (1) gate bulk lookups behind $295+/mo contracts or (2) return generic Klaviyo tags without the actual store details you need to qualify.
Here's the cheapest reliable path.
Pull a list of Shopify-store URLs from any source you trust (Built With Shopify directories, Built With's free Shopify lists, Shopify app reviews on the App Store, prior outbound). 1,000 to 10,000 URLs is a useful starting set.
Drop the URL list into fetchcraft's Shopify Store Detector actor. Set app_signals to true (it's the default). The actor returns every detected Shopify app per store, with Klaviyo as one of 25+ recognised fingerprints.
In the output dataset, filter to rows where apps_detected contains 'klaviyo'. That's your qualified list.
Pass the qualified domain list into Email Finder & Verifier to resolve the founder or marketing-lead contact. $0.02 per resolved email.
Pipe both outputs (store details + contact) into AI Sales Personalizer for a per-store cold-email opener that references their actual Klaviyo setup. $0.10 to $0.20 per lead.
| Step | Cost |
|---|---|
| 1,000 Shopify URLs scanned | $30 |
| Filter to Klaviyo present (typical 20 to 30% rate) | 200 to 300 qualified |
| Resolve 1 named contact each at $0.02 | $4 to $6 |
| AI opener per qualified store (optional, $0.10 each) | $20 to $30 |
| Total cost of a 200-lead Klaviyo-on-Shopify outbound list | $54 to $66 |
Compared with paying a data provider $295+/month for the equivalent dataset, this is a one-shot under $70 spend you control end to end.
