RetainIQ edges out Postscript SMS Marketing on rating (5.0★ vs 4.7★), but the gap is small enough that pricing fit and feature differentiation should drive the decision more than the headline number. Pricing entry tiers: Postscript SMS Marketing at Free trial available, RetainIQ at Free plan available. Check each app's tier structure for the capacity limits you actually need before deciding — the headline number is the same shape, but the gating shape per tier (apps, orders, integrations) varies. Postscript SMS Marketing has the larger user base (1,122 reviews vs 42), which usually maps to broader integration coverage, faster bug-fix cadence, and a deeper bench of community workflow patterns. RetainIQ's smaller cohort can be an advantage for niche workflows where the bigger app has accumulated bloat. Recommended by store size: small/early-stage merchants who need fast install and low risk should default to RetainIQ; mid-market and enterprise merchants with specific feature requirements should evaluate both — Postscript SMS Marketing's 1,122-review base may include the workflow context that matches your specific use case better than RetainIQ's broader-but-shallower coverage. This verdict is generated from the live marketplace data on this page — rating, review count, pricing tier, and category position all refresh from the canonical Shopify App Store listing every 24 hours. AppRanks does not accept payment to influence comparison outcomes; the methodology is documented on the About page and applies identically to every pair on the site.
