Sellify Post Purchase Upsell edges out Hulk Contact Form Builder on rating (5.0★ vs 4.8★), but the gap is small enough that pricing fit and feature differentiation should drive the decision more than the headline number. Pricing entry tiers: Hulk Contact Form Builder at Free plan available, Sellify Post Purchase Upsell at Free. 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. Hulk Contact Form Builder has the larger user base (1,882 reviews vs 18), which usually maps to broader integration coverage, faster bug-fix cadence, and a deeper bench of community workflow patterns.

Recommended by store size: small/early-stage merchants who need fast install and low risk should default to Sellify Post Purchase Upsell; mid-market and enterprise merchants with specific feature requirements should evaluate both — Hulk Contact Form Builder's 1,882-review base may include the workflow context that matches your specific use case better than Sellify Post Purchase Upsell'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.
