Klaviyo review
The industry standard for email + SMS automation
Best Overall in Email Marketing & SMS · Free plan · from ~$20/mo · 4.6/5 from 2,800+ reviews
Klaviyo is the app most Shopify email advice assumes you have. The segmentation engine is the real product: you can build audiences from browsing behaviour, predicted lifetime value and product affinity, then send email and SMS from one place. The price climbs with your list, and it climbs fast.
Where it wins
- Deepest segmentation of any Shopify email tool
- Email and SMS share one contact profile
- Predictive analytics on expected next order and churn risk
- Every major app integrates with it first
Where it falls short
- Pricing scales steeply past a few thousand contacts
- Most stores use a fraction of the feature set
- Support on lower tiers is slow
Skip it if
You have under five thousand subscribers and four or fewer flows. You are paying for an analytics team you don't have.
Features
- Advanced segmentation & predictive analytics
- Email + SMS in one platform
- Pre-built flows: welcome, abandoned cart, post-purchase
- Deep Shopify data sync (events, catalog, CLV)
Best for: Scaling brands that need the deepest data and automation.
