Littledata is purpose-built for Shopify Plus, offering server-side tracking directly from Shopify's servers — meaning it captures events browsers miss and enriches data GTM simply can't match.

Where Littledata wins:

  • vs. Retention.com: Retention.com focuses narrowly on identity resolution and Klaviyo flow recovery. It lacks server-side tracking, so it misses checkout events the browser doesn't see, limiting data completeness. Littledata covers Google, Meta, and Klaviyo with full checkout tracking, not just audience enrichment.

  • Unique Littledata advantages:

    • Server-side = no data loss from ad blockers or browser limitations
    • No-code, 10-minute setup (no dev team needed)
    • Native Shopify Markets support
    • 30-day free trial to validate ROI
    • Automatic checkout step tracking out of the box

For a Shopify Plus brand needing reliable, complete data across paid and owned channels, Littledata's infrastructure advantage is significant — Retention.com can't replicate server-side event capture.

Does Littledata work with Shopify?

Who owns Retention.com?

Retention.com(formerly GetEmails) is an independent private company headquartered in Austin, Texas. Adam Robinson is Retention.com's CEO.

When is Retention.com a better choice than Littledata?

Retention.com is a better choice if your goal is de-anonymising website traffic into contactable emails to grow owned email and SMS remarketing. Littledata is the better fit for teams who want turnkey, fully managed server-side tracking without building or maintaining tag infrastructure.

How is Littledata's tracking different from Google Tag Manager?

Littledata sends purchase and behavioural data server-to-server, directly from Shopify's servers, so it does not depend on browser tags or a Google Tag Manager container you have to maintain. Tracking keeps working when Shopify changes the checkout, and events can be enriched with customer and order data the browser never sees. Tools built on server-side Google Tag Manager still rely on browser tags to collect events, and someone has to build and maintain the container.

Do I need an implementation agency to set up Littledata?

No. Littledata is turnkey: install the Shopify app and server-side tracking is live, with no code and no Google Tag Manager required. Self-managed server-side setups typically need 10 to 40 hours of specialist configuration up front, plus a few hours a month of ongoing maintenance, which is why a low sticker price often hides a much higher true cost.

How does Littledata handle event editing?

Littledata's Event Editor lets you customise and enrich the events sent to each destination without code, so you control exactly what data reaches Google Analytics, Meta, Klaviyo and your other marketing tools.

What is Littledata's Profit signal?

Littledata's Profit signal sends true profit, not just revenue, to your ad platforms, so Meta and Google can optimise campaigns towards the orders that actually make you money.

Does Littledata protect against bot traffic?

Yes. Littledata's bot protection filters automated traffic out of your tracking, so your analytics and ad audiences are built on real customers.

Does Littledata support Shopify Markets and headless stores?

Yes. Littledata supports unlimited Shopify Markets for cross-border stores and headless and Hydrogen storefronts.
