Smile.io vs Stamped Loyalty: 2026 Comparison
Bottom line up front
Pick Smile.io for pure-play loyalty depth — focused product, generous free tier, broader integrations. Pick Stamped when you also use Stamped Reviews and want one unified vendor for reviews+loyalty; the bundle math wins. Smile.io's free tier (200 orders/mo) and lower paid pricing make it the better starting point for most Shopify brands; Stamped's edge is bundling, not standalone loyalty depth.

When to pick Smile.io
- You want pure-loyalty focus without reviews bundle pressure. Smile.io is loyalty-only, focused product depth.
- You\'re on a different reviews platform you like (Yotpo, Loox, Junip, Okendo). Pair with Smile.io and avoid Stamped lock-in.
- You want a real free tier. Smile.io 200 orders/mo free is meaningful for new brands.
- Klaviyo integration depth matters. Smile.io has a slightly more polished Klaviyo integration.
- Branding customization is important early. Smile.io advanced branding starts at Starter $49/mo; Stamped at Growth $149/mo.
When to pick Stamped
- You already use Stamped Reviews. Bundle math wins, integration between products is genuinely useful.
- Earn-points-for-verified-review is part of your strategy. Stamped Reviews + Loyalty does this natively.
- You want lower-cost VIP entry. $149/mo Growth tier vs Smile.io $199/mo Growth.
- You want a single vendor for Reviews + Loyalty + Lifecycle messaging. Stamped\'s bundle covers all three; Smile.io is loyalty-only.
- Multi-store / multi-currency Shopify Plus brand. Stamped Enterprise handles this; Smile.io support here is shallower.
Decision tree
- Already using Stamped Reviews? → Stamped Loyalty (bundle math).
- Already using Yotpo Reviews? → Smile.io or Yotpo Loyalty.
- Need both reviews + loyalty and want one vendor? → Stamped.
- Pure loyalty focus + already on Klaviyo? → Smile.io.
- Free tier essential? → Smile.io.
- $2M+ GMV with VIP tiers needs? → Look at LoyaltyLion vs Stamped instead.
Frequently asked
Is Smile.io or Stamped better for Shopify loyalty?
For pure-loyalty focus, Smile.io — deeper, more focused product, broader integrations. Stamped is reviews-first with a loyalty add-on; the loyalty product is solid but less deep than Smile.io. The decisive question is whether you want one vendor for reviews+loyalty (Stamped) or best-of-breed for each (Smile.io + a separate review platform).
How much does Stamped Loyalty actually cost?
Stamped Loyalty Starter is $59/mo (up to 1,000 orders/mo), Loyalty Growth is $149/mo, Loyalty Enterprise from $399/mo. The Reviews-only product is $199/mo. The full bundle (Reviews + Loyalty + Lifecycle) lands close to $800/mo before bundle discount. For brands using both reviews and loyalty, Stamped's bundle pricing is meaningful; for loyalty-only, Smile.io is cheaper at most volumes.
Which has better Shopify integration?
Both are Shopify-first products with native app installs. Smile.io feels more Shopify-native because loyalty is its only product; Stamped is split across reviews and loyalty so neither product gets exclusive engineering focus. For pure loyalty depth, Smile.io. For unified reviews+loyalty workflow, Stamped.
Are referrals included in Stamped Loyalty?
Yes, on every Stamped Loyalty plan from Starter ($59/mo) up. Smile.io includes referrals on every paid plan from Starter ($49/mo) up. Both have basic double-sided rewards and fraud detection. Neither matches LoyaltyLion's referral depth — if referrals are a primary acquisition channel, look at LoyaltyLion instead.
What about VIP tiers?
Stamped Loyalty VIP tiers are on Growth ($149/mo) and above. Smile.io VIP tiers are on Growth ($199/mo) and above. Functionally similar — milestone celebrations, tier-exclusive perks, points multipliers. Stamped has slightly cheaper entry to VIP at $149 vs $199; Smile.io's VIP UI is more polished.
Which is easier to set up?
Both are roughly equivalent — Shopify App Store install, basic program live in 1-2 hours. Stamped's combined reviews+loyalty installer adds slight complexity if you're using both products; Smile.io is single-product simplicity. For a same-day launch, both are fine.
Should I use Stamped if I already have Yotpo Reviews?
No — running Stamped Loyalty alongside Yotpo Reviews defeats the purpose of the Stamped bundle and you're better off on Smile.io (or Yotpo Loyalty) for the loyalty piece. Vendor consolidation only makes sense if you go all-in on one stack; mixed deployments are usually worse than committed best-of-breed.
