Referral + loyalty tied to sub tier, Smile / LoyaltyLion / Yotpo?

The cheapest-CAC growth channel for mature sub-box brands. Three loyalty platforms I integrate most:

• Smile.io, the default for $500k, $10M brands. Cleanest sub-tier integration (auto-tiers based on months-on-sub). Pricing: $49, $999/mo. Native ReCharge + Smartrr integrations. Referral flow built-in (refer friend → both get $X off).
• LoyaltyLion, deeper for $5M+ brands. Better reporting, more flexibility on point-earning rules, native VIP tier orchestration. Pricing: $399, $1,599/mo. Integrates with ReCharge.
• Yotpo Loyalty, best if you’re already on Yotpo for reviews. Cross-product synergy: loyalty points for reviews, loyalty points for referrals, all under one platform. Pricing: bundled with Yotpo Reviews ($259, $1,200/mo).

Tier model that works for sub boxes:

• Bronze (months 1-3), standard rewards earn rate.
• Silver (months 3-6), 1.5x earn rate, free shipping on add-on shop.
• Gold (months 6-12), 2x earn rate, early access to limited theme boxes.
• Platinum (12+ months), 2.5x earn rate, free swag every quarter, exclusive limited drops, first dibs on member events.

Referral mechanics: refer a friend, both get $10 off next box. Combined referral + tier loyalty drives 12-20% of new sub acquisitions for brands that wire this in well, cheaper CAC than paid social on $1M+ Meta-ads spend.
