How does AppRanks pick the top Email marketing apps for Shopify App Store?

Apps appear here because Shopify App Store itself classifies them under Email marketing — AppRanks does not editorially add or remove apps from this category set. Within the category, ranking uses average rating times the natural log of review count (rating × ln(reviewCount + 1)), which keeps a single 5-star outlier from leapfrogging an established listing while still letting a very-well-rated mid-volume app rank above a poorly-reviewed giant. The page refreshes daily from the canonical Shopify marketplace listing. AppRanks does not accept payment to alter ranking on public surfaces.

How often does this email marketing apps list update?

Every 24 hours. AppRanks pulls fresh rating, review count, and pricing-tier data from each app's Shopify marketplace listing nightly. Apps that lose Shopify App Store's category tag (e.g., a developer changes the listing's primary category) drop off in the next nightly snapshot. The page itself is cached at the CDN for 1 hour to absorb traffic spikes, so during a refresh window the visible list lags the underlying data by at most one hour.

What does "Pick if" mean on each top-3 entry?

"Pick if" is a data-derived recommendation that surfaces the most useful selection criterion for that app — high rating with deep review base means category default; free tier with broad adoption means budget-first pick; high rating with moderate review count means satisfaction-led pick. The framing is generated from the same rating + review count + pricing data shown on the card, not from editorial judgment or paid placement.

Where can I see the full methodology and audit scoring?

The full methodology — including the rating × ln(reviewCount + 1) blend, refresh cadence, conflict-of-interest policy, and the per-app audit-score breakdown — is documented on the AppRanks About page and the audit-score glossary entry. Every app on this list also has a dedicated audit page that walks through title, content, visuals, pricing, and category-tag scoring against the marketplace's published standards.
