What is Klaviyo?

Klaviyo is a marketing automation and B2C CRM platform built primarily for ecommerce and DTC brands, unifying email, SMS, push, and customer data in one system. It's best known for its deep, real-time integration with Shopify (and other ecommerce platforms), which lets brands segment audiences and trigger automated flows based on purchase and browsing behavior. Pricing is usage-based, scaling with the number of active profiles plus separate SMS credits, so costs grow as a brand's list and sending volume expand.

Best known for: Ecommerce email + SMS with deep Shopify data

Key features

  • Ecommerce email marketing with templates
  • SMS/MMS and mobile push, unified with email

Who Klaviyo is best for

  • Teams running ecommerce or DTC brands that want email and SMS in one platform

Costs to watch before you commit

  • Pricing scales steeply with active profiles — cost grows automatically as your list expands, with no flat rate.
  • SMS/MMS credits are billed separately on top of the profile price and can dwarf the base cost for heavy senders.
  • Add-on products (Reviews, Customer Service, advanced Data) cost extra, and support degrades on lower tiers.
