About Klaviyo
What Is Klaviyo
Klaviyo is a customer relationship platform built for online sellers. It brings order history, browsing activity, and support conversations into a single customer profile, then uses that profile to run email and SMS marketing and answer customer questions. The product started as an email tool for Shopify stores and has grown into a broader B2C CRM with an AI assistant layer called Klaviyo AI. As an email marketing platform it began with campaigns, and it now covers far more.
The problem it solves is fragmentation. Most small stores run one tool for email, another for texts, and a third for service, so the same shopper looks like three different people. Klaviyo unifies those signals so a welcome offer, an abandoned-cart nudge, and a support reply all read as coming from one brand. That matters because shoppers notice when a message contradicts the last one they got.
The main limit is scale and complexity. Klaviyo prices by active profiles rather than by emails sent, so a large list costs more even if you rarely mail it. Its automation builder rewards people who plan flows carefully, and stores that just want a simple monthly newsletter may find dedicated tools lighter on setup.
Getting Started
- Create a Klaviyo account and pick your industry during onboarding.
- Connect your store, typically Shopify, WooCommerce, or BigCommerce, so order and product data sync automatically.
- Import or grow your contact list, then set up a sending domain for deliverability.
- Build a welcome flow or a first campaign with the drag-and-drop editor or a prompt in Composer.
- Review performance in the analytics dashboards and adjust segments and timing.

Key features
Omnichannel Marketing Automation
Klaviyo sends across email, SMS, mobile push, and WhatsApp from one flow builder. You set the trigger, like a first purchase or a browse-without-buy event, and the platform picks the channel and timing. The value is consistency: a shopper who opens email but ignores it can still get a text.
Klaviyo AI and Composer
Composer is a marketing agent that scans your account for problems, such as overlapping audiences or a declining campaign, and proposes fixes using your own data and brand voice. Klaviyo says every recommendation is reviewed by you before it goes live. Customer Agent applies the same data to answer shoppers on its own.
Predictive Segmentation
Segments build themselves from real behavior rather than static lists. You can target predicted lifetime value, churn risk, or a specific product view, and Klaviyo updates the group as behavior changes. This keeps a campaign aimed at 2,000 people from quietly mailing the wrong 2,000 a month later.
Customer Data Platform
The Klaviyo Data Platform resolves signals from your site, app, point of sale, and loyalty tools into one profile per customer. Klaviyo says it processes more than four billion signals daily across more than twenty billion profiles. Identity resolution connects activity across browsers and devices, which reduces duplicate profiles and repeat messaging.
Analytics and Reporting
Prebuilt and custom dashboards track revenue per campaign, attribution across channels, and funnel drop-off. Benchmark data shows how your open and click rates compare with similar stores, so you know whether a weak number is your problem or the season.
Integrations and APIs
Klaviyo connects to more than 350 apps and exposes over 495 APIs. The list spans the major commerce, shipping, and loyalty platforms. Teams that already run a data warehouse can activate audiences from Snowflake or Databricks and send engagement data back for analysis.
Pros and cons
Pros
- Deep ecommerce email marketing integration feeds order and product data into segmentation without custom code.
- Email, SMS, push, and WhatsApp live in one flow builder, so you manage one automation instead of four.
- Predictive segments update on their own, which cuts the manual list work that eats marketing hours.
- The free tier covers a small store with up to 250 contacts and 500 monthly sends.
- Analytics and benchmarks give clear readouts on which campaigns actually earn revenue.
Cons
- Pricing scales with stored contacts, not sends, so a large dormant list costs the same as an active one.
- The automation builder has a learning curve; simple newsletters may not need this much tooling.
- Advanced AI features and the higher sending tiers sit behind more expensive plans.
- Some integrations need a paid app or developer help, so setup time adds up.
