What is Klaviyo?
Klaviyo is the leading Shopify email and SMS marketing platform. It offers automated flows, segmentation, A/B testing, predictive analytics, and deep Shopify integration. Pricing starts free for up to 250 contacts, with paid plans based on list size. It has a 3.9 rating across 2,000+ reviews and powers email for 100,000+ Shopify stores.
Where Klaviyo Falls Short
Traffic Driver, Not AOV Architecture
Klaviyo drives visits through email and SMS. It does not build the shopping experience that determines what customers buy per visit. High email open rates at low AOV is a volume game, not a profit game.
No Bundle Builder or Progressive Cart Rewards
Klaviyo sends messages. It does not build guided bundle experiences with tiered pricing, combined rewards, or step-by-step product selection. The on-site experience needs a separate tool.
Email Discounts Feed the Death Spiral
Klaviyo flows often include percentage-off discount codes. These train customers to wait for the next email. Bundle value stacking rewards buying more right now without price cuts.
Completely Different Problem Domain
Klaviyo solves the 'how do I get customers back' problem. Tiergain solves the 'how do I make each visit worth more' problem. Both are critical. They need different tools.
