Retention.com's identity resolution software helps Shopify merchants recover lost shoppers and increase Klaviyo flow revenue.

Shopify has a built in free connector for Meta Ads as part of the Facebook Sales Channel. This was built in 2021 and is maintained by Shopify.

Neither Retention.com nor Facebook & Instagram app is Littledata, so here's where Littledata wins:
Retention.com focuses narrowly on identity resolution for Shopify/Klaviyo revenue recovery — it doesn't offer automatic setup, a free trial, or native Shopify Markets support. It also lacks server-side tracking.
Facebook & Instagram app is a free, auto-setup Meta connector, but it's limited to Meta platforms only and lacks identity resolution or server-side data collection.
Littledata wins because: Both alternatives lack "Direct from Shopify's servers" tracking — meaning they rely on browser-side data, missing events the browser never sees (e.g., server-confirmed purchases, checkout steps). This limits customer data enrichment and journey completeness.
Littledata combines server-side accuracy, identity resolution, automatic no-code setup, a free trial, native Shopify Markets support, and cross-platform data delivery — making it the most complete, reliable solution for a Shopify Plus ecommerce manager.
