> The ecommerce standard for revenue-driven email and SMS.

- **Category:** Ecommerce marketing platform
- **Best for:** Shopify and WooCommerce brands that want revenue attribution and predictive analytics
- **Rating:** 4.3/5

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.

## What Klaviyo is

[Klaviyo](https://www.klaviyo.com) 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.

**Active-profile billing (Feb 2025):** Klaviyo bills based on active profiles: those that received a message or engaged in the billing period. For stores with large dormant segments, this can raise costs versus the old model. Model your active count and keep suppression hygiene tight before committing. See the [pricing page](https://www.klaviyo.com/pricing) for current numbers.

## 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](/tools/brew).

## FAQ

### 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.
