What is Klaviyo?

Klaviyo is a cloud based email marketing and SMS platform built primarily for ecommerce and consumer brands. It combines a customer data platform with marketing automation, letting businesses unify behavioral, transactional, and engagement data to build segments, automated flows, and personalized campaigns across email, SMS, and mobile push. Klaviyo is widely used by Shopify, WooCommerce, BigCommerce, and Magento merchants for automations such as abandoned cart, welcome series, and post purchase flows.

The platform offers a free plan for up to 250 profiles and 500 monthly emails, with paid Email and Email plus SMS plans that scale in price as contact list size grows. Core features include a drag and drop email builder, prebuilt automation templates, predictive analytics, A/B testing, and reporting benchmarked against peer brands. Klaviyo integrates with over 350 ecommerce and business tools and is known for deep segmentation capabilities, though pricing rises quickly as subscriber lists grow.

Klaviyo FAQs

Yes. Klaviyo offers a permanent free plan (not just a trial) for up to 250 active profiles and 500 email sends per month, plus 150 mobile messaging credits. There is no credit card required and no expiration date, though full support access is limited to the first 60 days.

Klaviyo's Email plan is priced by active profile count: roughly $20/month at 500 contacts, $30/month at 1,000 contacts, $100/month at 5,000 contacts, and $400/month at 25,000 contacts. Email plus SMS plans cost more due to added mobile messaging credits. Pricing increases are capped at 25% per adjustment.

As of February 18, 2025, Klaviyo bills based on total active profiles in the account rather than only profiles emailed or texted in the prior 90 days, so cold and suppressed contacts can count toward your bill.

Klaviyo offers 350+ prebuilt integrations, including deep native integrations with Shopify, WooCommerce, BigCommerce, Magento, Square Online, Wix, and Salesforce Commerce Cloud, plus connectors for ad platforms, payment providers, and CRMs.

Yes. Beyond email, Klaviyo supports SMS, MMS, WhatsApp, RCS, and mobile push notifications, all manageable from the same platform using shared customer segments and automated flows.

Klaviyo is powerful but has a learning curve. Reviewers on G2 and Capterra frequently note that advanced flows and segmentation can feel complex to set up initially, though the platform provides prebuilt flow templates and onboarding resources to help new users get started.
