Omnisend Email Marketing & SMS edges out WarmInbox on rating (4.7★ vs 4.6★), but the gap is small enough that pricing fit and feature differentiation should drive the decision more than the headline number. Pricing entry tiers: Omnisend Email Marketing & SMS at Free to install, WarmInbox at Free trial 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. Omnisend Email Marketing & SMS has the larger user base (2,962 reviews vs 5), which usually maps to broader integration coverage, faster bug-fix cadence, and a deeper bench of community workflow patterns. WarmInbox'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 Omnisend Email Marketing & SMS; mid-market and enterprise merchants with specific feature requirements should evaluate both — WarmInbox's 5-review base may include the workflow context that matches your specific use case better than Omnisend Email Marketing & SMS'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.
