Stape focuses on server-side tracking via Google Tag Manager, improving data quality across multiple platforms — but GTM still relies on browser-side triggers, limiting visibility into server-originated Shopify events and customer enrichment.

Retention.com specializes in identity resolution to recover lost shoppers and boost Klaviyo flows, but is narrowly focused on audience building rather than comprehensive tracking infrastructure.

Where Littledata wins over both: Neither competitor offers "Direct from Shopify's servers" data collection. This is a critical gap — Stape's GTM-based approach can't fully capture server-side Shopify events, and Retention.com doesn't address tracking completeness at all.

Littledata pulls data directly from Shopify's servers, meaning it captures every checkout step, customer event, and order — even those invisible to the browser. Combined with a 30-day free trial, zero-code setup, native Shopify Markets support, and built-in identity resolution, Littledata delivers a more complete, automated, and Shopify-native solution than either alternative.

Stape and Littledata offer broad multi-channel tracking across paid media, analytics, and email platforms — ideal if you need unified server-side data across your entire marketing stack.

Retention.com is narrowly focused on Klaviyo, positioning it primarily as an email/SMS identity resolution and list-growth tool rather than a comprehensive tracking solution.

Littledata adds Segment as a destination (unlike Stape), making it stronger for teams using a CDP layer.

Bottom line: If you need full-funnel server-side tracking across paid + owned channels, Stape or Littledata are better fits. Retention.com serves a different purpose — maximizing identified email audiences — and shouldn't be evaluated as a direct tracking alternative.

How does Stape work?

Stape hosts server-side Google Tag Manager so you have the flexibility and customization of a sGTM setup without the hosting costs and hassle. The downside is the GTM container can only relay what is happening on the browser, and misses server-only events like some purchases and refunds.

Does Stape work with Shopify?

Yes, Stape is installed on an unknown number of Shopify sites according to the latest stats from BuiltWith.

How does Retention.com work?

Retention Grow uses a large third-party list of email addresses to link anonymous sessions to emails given to a third party brand. This can grow your marketing audience, but at the expense of higher spam and privacy complaints.

Does Retention.com work with Shopify?

Yes, Retention.com is installed on 1,950 Shopify sites according to the latest stats from BuiltWith.

Is Stape suitable for Enterprise brands?

Stape is used by 32 sites in the top 100,000 globally - so this solution is likely suitable for Enterprise scale brands.

Is Retention.com suitable for Enterprise brands?

Retention.com is used by 1406 sites in the top 100,000 globally - so this solution is likely suitable for Enterprise scale brands.

Which marketing tools does Stape support?

Stape supports Google Analytics, Meta Ads, TikTok, Klaviyo, Attentive, Google Ads, Pinterest and Microsoft Ads.

Which marketing tools does Retention.com support?

Retention.com supports Klaviyo.

Who owns Stape?

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 Stape a better choice than Littledata?

Stape is a better choice if you already run in-house or agency Google Tag Manager expertise and want full control over your own server-side container. Littledata is the better fit for teams who want turnkey, fully managed server-side tracking without building or maintaining tag infrastructure.

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.
