Elevar vs Retention.com
Elevar focuses on comprehensive conversion tracking via server-side Google Tag Manager, delivering data to multiple marketing platforms. However, following its acquisition by Buxton/Audiense, it has been absorbed into a broader analytics tool, meaning it's no longer a focused tracking solution for Shopify Plus merchants.
Retention.com is narrower in scope — primarily identity resolution to recover lost shoppers and boost Klaviyo flows, rather than full conversion tracking infrastructure.
Where Littledata wins over both:
Neither is Littledata, so it's worth considering. Retention.com lacks Direct from Shopify's servers, limiting its ability to enrich events with customer data or capture events the browser misses. Elevar relies on Google Tag Manager, which still depends on browser tags and can't capture a complete customer journey.
Littledata adds: a 30-day free trial, fully automatic no-code setup, native Shopify Markets support, and automatic checkout step tracking — server-side, directly from Shopify, with zero implementation overhead.

Elevar and Littledata offer broad multi-channel server-side tracking across paid media, analytics, and email/SMS platforms — covering Google, Meta, TikTok, Pinterest, Microsoft, and more. Their strength is comprehensive ad attribution and analytics accuracy.
Retention.com is fundamentally different in purpose: it's not a tracking infrastructure tool but an identity resolution platform focused on identifying anonymous visitors and syncing them to Klaviyo for email/SMS remarketing. Its "data destination" is narrow by design.
Bottom line: Choose Elevar or Littledata for full-funnel server-side event tracking across ad platforms. Choose Retention.com specifically to recover lost email audiences — they solve different problems and are often used together.
