Scope
What this comparison measures.
What it measures
Shopify App Store ratings, review counts and 30-day review growth, listed pricing and capabilities, category data, and OngoingAI-observed storefront adoption for Klaviyo and Mailchimp Email SMS Marketing.
What it doesn’t
Hands-on usability, customer-support quality, deliverability, merchant sentiment from review text, or revenue impact. We draw a sharp line around what we can observe.
Methodology
Where the numbers come from.
Ratings, review counts, pricing, and categories come from the live Shopify App Store listing, refreshed daily. Review growth compares the observed snapshots across the trailing 30-day window. “Stores observed” and the platform split come from OngoingAI’s weekly storefront census — the real stores running each app, not the listing’s claimed totals. Comparison generated Aug 25, 2026.
