Observed adoption
Who actually runs each, on real stores.
The stores OngoingAI’s weekly census observes running each app, and the platform each skews toward — observed presence, not vendor-reported install totals.
Adoption comparison unavailable — a publishable footprint exists for only one app.

No reliable footprint yet
OngoingAI hasn’t observed enough high-confidence installations to publish an adoption count. This does not mean zero installations.
Scope
What this comparison measures.
What it measures
Shopify App Store ratings and review counts, rating distribution, developer reply rates, reviewer tenure and geography, listed pricing and capabilities, category data, and OngoingAI-observed storefront adoption for Mailchimp and Constant Contact.
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 27, 2026.
