Eternly Analytics review
Detailed subscription cohorts and retention recommendations for Shopify-focused commerce teams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Eternly Analytics is a web-based retention analytics service for Shopify merchants running subscription businesses. It combines Shopify data with Recharge, Loop Subscriptions or Skio data, then organizes retention cohorts from M+1 through M+12. Subscription teams can examine RFM segments, customer lifetime value at 3, 6, 12 and 24 months, MRR and ARR components, churn reasons, repurchase behavior, rebill success, product affinity and winback timing. Longevity Leon adds AI-generated retention recommendations, while Klaviyo synchronization supports profile and segment activation.
Pricing is structured around three monthly paid plans, with a Free tier also available. Growth costs $99 per month and includes Full Analytics, Klaviyo Sync, a Recommendations log and one Leon request per day. Scale costs $199 per month, adds five Leon requests per day and Priority support, and includes everything in Growth. Pro costs $299 per month and adds unlimited Leon requests, a Dedicated CSM, image and CSV analysis exports, and Slack support. Growth and Scale include a 14-day trial without a credit card; accounts revert to the Free tier when no paid plan is selected.
Eternly fits teams whose commerce and subscription data already run through Shopify, Recharge, Loop Subscriptions or Skio, with Klaviyo available for activation workflows. Nightly synchronization and historical imports of up to five years support ongoing cohort review. The product is delivered through the cloud as a web dashboard, with email and documentation support and GDPR compliance. Teams needing warehouse imports, broader commerce-platform coverage or a non-Shopify data foundation should consider an alternative. Shopify subscription brands seeking focused churn, rebill and winback analysis are the clearest match.
