Klaviyo is a marketing platform that the vendor describes as a CRM for B2C businesses. Email, SMS, WhatsApp, push, reviews and a helpdesk draw on one customer profile, and the vendor says its AI agents build campaigns and answer support questions. Its integrations pages lead with the ecommerce platforms Shopify and BigCommerce.
What agencies use Klaviyo for
The vendor’s Shopify page points to agency and technology partners and a partner directory, and says Klaviyo is a BigCommerce elite partner and a Shopify Sidekick launch partner. The pages read include no page written for agencies.
An agency running email and SMS for an ecommerce client can use the segmentation, automated flows and reporting the free plan lists. The vendor’s Composer agent, it says, audits flows and segments and builds a campaign from one prompt.
Klaviyo pricing
Klaviyo’s price is set by active profiles, and each product is priced separately. The pricing page is a plan builder, in US dollars, rather than a fixed list.
| Plan or product | Price | Basis | Main limits |
|---|---|---|---|
| Free | $0 | Monthly | Up to 250 active profiles, 500 email sends a month |
| $20 a month | For 500 active profiles | 5,000 emails a month | |
| Composer | $20 a month | Add-on | AI agent; $10 usage increments |
| Mobile messages | Per message | By volume and destination | About $0.01 for a United States toll-free text, plus provider fees |
Email, Customer Hub and other profile-based products rise with the profile slider, so the $20 figure is the entry point. The free plan includes $5 of mobile messages and $5 of Composer usage a month, and email support for the first 60 days. The page shows no free trial of the paid Email plan; it names a free 30-day trial for Customer Hub.
What it connects to
The vendor says Klaviyo connects to 350 or more apps, in groups such as advertising, loyalty, helpdesk, shipping and logistics, subscriptions, and quizzes and surveys. It has built-in connections for Shopify and BigCommerce, and exports to data warehouses including Snowflake and BigQuery. Open APIs and webhooks cover custom tools, and an MCP server and a ChatGPT integration are named on its pages.
Limits to know before you buy
The free plan stays free while an account has at most 250 active profiles and 500 monthly email sends. Past that, sending may be restricted, and features such as removing Klaviyo branding need a paid plan. Email and the other profile-based products rise as the list grows.
Mobile messaging is billed separately from email, by country, and provider fees are added to the per-message figure.
