The ecommerce standard for revenue-driven email and SMS.
Campaign Compass rating
The most complete ecommerce toolkit. Powerful but can get expensive at scale, and the Feb-2025 active-profile billing change rewards list hygiene.
- Best for
- Shopify and WooCommerce brands that want revenue attribution and predictive analytics
- Pricing
- Free up to 250 contacts; email from ~$20/mo (500 contacts), scaling with list size
- Category
- Ecommerce marketing platform
Klaviyo is the de-facto standard for ecommerce email and SMS. Its native commerce data model, pre-built revenue flows, and predictive analytics make it hard to beat for Shopify and WooCommerce stores: though costs and billing mechanics reward disciplined list management.
Strengths
- Deep native ecommerce integrations (Shopify, WooCommerce, BigCommerce, Magento)
- Revenue-attributed reporting makes ROI math straightforward
- Best-in-class abandoned-cart, post-purchase, and win-back flow templates
- Predictive analytics (next purchase date, customer lifetime value) that are genuinely useful
- Large ecosystem of agencies and freelancers fluent in the platform
Trade-offs
- Pricing climbs steeply as your list grows
- Active-profile billing (since Feb 2025) can raise costs for large dormant segments
- SMS is billed separately, per message
- Email creation is drag-and-drop with only limited AI assist
What Klaviyo is
Klaviyo is a marketing platform built around an ecommerce data model: profiles plus product and order data. That foundation is what powers its revenue-attributed reporting and its library of commerce flows. For Shopify and WooCommerce brands, it is frequently the fastest path to a meaningful lifecycle program.
In recent cycles Klaviyo has expanded beyond pure ecommerce: a CDP tier and pushes into subscription, hospitality, and media verticals make it a legitimate broader B2C option. It has also shipped agentic campaign optimization for use cases like replenishment and win-back.
Where Klaviyo wins
- Commerce data: orders, products, and customers sync from Shopify and WooCommerce without custom development.
- Revenue flows: abandoned cart, browse abandonment, post-purchase, and win-back templates are mature and effective.
- Predictive analytics: estimated next order date and customer lifetime value feed segmentation directly.
- Ecosystem: a deep bench of agencies and freelancers know the platform well.
Pricing and the billing change
Klaviyo offers a free tier (up to 250 contacts, 500 sends). Paid email plans start around $20/month for 500 contacts and scale with list size: roughly $150/month at 10,000 contacts and higher from there. Email + SMS plans start higher, and SMS is billed per message.
The verdict
If you run an ecommerce store on Shopify or WooCommerce, Klaviyo remains the safe, capable default: its commerce data model and revenue flows are difficult to replicate elsewhere. Watch the active-profile billing as you scale, and pair it with strong list hygiene. Teams whose real bottleneck is producing on-brand creative quickly often pair or compare it with an AI-native generator like Brew.
Frequently asked
- Is Klaviyo good for non-ecommerce businesses?
- It can be. Klaviyo has expanded with a CDP tier and into subscription, hospitality, and media verticals, but its core strength and best templates remain ecommerce-focused.
- Why did my Klaviyo bill go up?
- In February 2025 Klaviyo moved to active-profile billing, charging based on profiles that received a message or engaged during the period. Large dormant segments can increase costs, so suppression and re-engagement hygiene matter.
