The default email platform for online stores, especially on Shopify: flows, segments and product recommendations run on order data, but you pay for every profile you can email and the bill climbs steeply as a store grows.
What it is
Klaviyo syncs orders, products and browsing from stores such as Shopify, WooCommerce and BigCommerce, then runs abandoned-cart, browse and post-purchase flows, segmentation on purchase behavior, product recommendations and predictive analytics, with SMS, reviews and a customer hub as extra products. Free: up to 250 active profiles and 500 emails a month, with Klaviyo branding. Email plan $20 a month for 500 active profiles and 5,000 emails; Marketing plan $25 at the same size adds social marketing, reviews and Customer Hub (first month $1 under a limited-time offer). Prices rise with active profiles, which count everyone you can email, including shoppers who gave an address at checkout: $150 a month at 10,000 profiles and $350 at 15,000 on the Email plan in dated captures of the calculator; custom above 150,000. SMS is an add-on. Plan prices from klaviyo.com/pricing and the Klaviyo help center checked November 13, 2026; profile-tier prices from captures dated October 25 to November 3, 2026.
Best for
- Shopify and other online stores
- Revenue-driven flows like abandoned cart and post-purchase
- Stores that want email and SMS on the same customer data
What we like
- Deep store integrations feed flows, segments and product recommendations
- Strong prebuilt ecommerce flows and revenue attribution
- Email, SMS, reviews and a customer hub on one profile
- Free plan to start with up to 250 active profiles
What to watch
- Expensive at scale: $150 a month at 10,000 profiles jumps to $350 at 15,000
- Every emailable profile counts, including checkout-only shoppers
- Steeper learning curve than newsletter tools
- Overkill and overpriced for a plain newsletter
