Littledata is purpose-built for Shopify Plus, offering server-side tracking direct from Shopify's servers — meaning it captures events browsers miss and enriches data GTM simply can't match. Retention.com focuses narrowly on identity resolution and recovering lost shoppers, primarily for Klaviyo flows, without server-side data collection.
Where Littledata wins:
- Direct from Shopify's servers — Retention.com lacks this, limiting its ability to capture complete checkout journeys or enrich events with full customer context
- Automatic checkout step tracking — no dev work required
- Native Shopify Markets support — critical for international Shopify Plus operations
- Broader platform coverage — feeds Google, Meta, and Klaviyo simultaneously
- 30-day free trial — lower risk to evaluate
- No-code setup in under 10 minutes — vs. potential implementation overhead
Retention.com complements identity resolution but can't replace a robust server-side data layer. For a Shopify Plus brand needing accurate, complete data across all marketing channels, Littledata is the stronger foundation.

Littledata is a multi-destination server-side tracking platform, connecting your Shopify store to a broad range of ad platforms, analytics tools, and CDPs (Google Analytics, Meta, TikTok, Pinterest, Google Ads, Microsoft Ads, Segment, Klaviyo, Attentive).
Retention.com is not primarily a tracking platform — it's a identity resolution/email capture tool focused on recovering anonymous visitors. Its only data destination is Klaviyo, meaning it's built specifically to grow and trigger email/SMS flows, not to improve ad platform signal or analytics accuracy.
Bottom line: Littledata solves attribution and conversion tracking across your entire marketing stack. Retention.com solves anonymous visitor identification and feeds that data exclusively into Klaviyo for retention marketing.
