Our verdict on Klaviyo
Klaviyo is a B2C CRM and email marketing platform for consumer brands, with a particular fit for ecommerce teams focused on personalized customer journeys. It combines email campaigns, automated flows, audience segmentation, unified customer profiles, landing pages, analytics, and multichannel messaging. Marketers can create campaigns with customizable templates and drag-and-drop editing, then trigger messages from customer behavior, events, and profile properties.
Pricing begins with a Free plan at $0 per month, including up to 250 active profiles, 500 emails per month, built-in reporting, and email support. The Paid marketing plan starts at $45 per month, with pricing varying by active profiles and selected products. The platform also supports email campaign A/B testing for subject lines, content, and send times. AI features can generate copy, graphics, subject lines, and audiences, while hosted landing pages add another campaign destination.
Klaviyo’s ecosystem includes 350+ apps, APIs, webhooks, and data-warehouse connections for Snowflake, BigQuery, and Azure. It is available through the web and API, and supports email, SMS, and mobile push campaigns and flows. That breadth suits teams coordinating customer data and messaging across several channels. Smaller teams with up to 250 active profiles can start with the free tier, while growing brands should evaluate the monthly paid cost against their profile and messaging needs. Organizations seeking only basic email newsletters may find the broader CRM, automation, and multichannel scope more than they need.
