What is Klaviyo?

Klaviyo is an email and SMS marketing platform built for ecommerce businesses that want to use consented customer and commerce data in lifecycle messaging.

What sets Klaviyo apart from general-purpose email tools like Mailchimp is its deep integration with ecommerce platforms — particularly Shopify. Klaviyo syncs every customer action in real time: purchases, product views, cart additions, refunds, and more. This data powers hyper-personalized automation flows that send the right message to the right customer at exactly the right moment.

Klaviyo offers analytics, segmentation, and automation capabilities that should be evaluated against your data quality, lifecycle strategy, consent process, and measurement model.

What to Evaluate in Klaviyo

Six core capabilities that make Klaviyo the most effective email marketing platform for ecommerce.

Built for Ecommerce

Klaviyo was designed from the ground up for online stores. Every feature — from abandoned cart flows to post-purchase sequences — is optimized to drive revenue, not just open rates.

Pre-Built Automation Flows

Launch proven revenue-generating automations in minutes: welcome series, abandoned cart, browse abandonment, post-purchase, win-back, and more. All customizable with a visual drag-and-drop editor.

Advanced Segmentation

Segment your audience based on purchase history, browsing behavior, predicted lifetime value, and 200+ data points. Send the right message to the right person at the right time.

Email + SMS in One Platform

Manage both email and SMS marketing from a single dashboard. Coordinate multi-channel campaigns and flows without juggling separate tools or data sources.

Campaign Reporting

Review campaign, flow, and segment reporting alongside your own analytics and attribution assumptions before making budget decisions.

Deep Shopify Integration

Klaviyo syncs every customer action from your Shopify store in real time — purchases, refunds, product views, cart additions. Use this data to trigger hyper-personalized messages automatically.

Frequently Asked Questions

How does Klaviyo's abandoned cart flow work?

When a customer adds items to their cart and leaves without purchasing, Klaviyo automatically triggers a sequence of emails (and optionally SMS) reminding them to complete their purchase. You can customize timing, copy, and incentives. On average, abandoned cart flows recover 5–15% of lost revenue.

Can I migrate from Mailchimp to Klaviyo?

Yes. Klaviyo has a built-in Mailchimp import tool that migrates your contacts, segments, and historical data. The migration typically takes under an hour. Klaviyo also provides onboarding support for migrating brands.

Does Klaviyo have a free plan?

Yes. Klaviyo's free plan supports up to 250 contacts and 500 email sends per month, plus 150 free SMS/MMS credits. It includes access to flows, templates, and basic segmentation — enough to get started and see results before upgrading.

What is Klaviyo's deliverability like?

Klaviyo has excellent deliverability, consistently ranking among the top email platforms. They provide dedicated IP addresses for high-volume senders, domain authentication setup, and a deliverability hub with actionable recommendations to keep your emails out of spam.

Can Klaviyo integrate with platforms other than Shopify?

Yes. Klaviyo integrates with WooCommerce, BigCommerce, Magento, Wix, Squarespace, and 300+ other platforms. It also has a robust API for custom integrations.

How does Klaviyo compare to ActiveCampaign?

Klaviyo is better for ecommerce; ActiveCampaign is better for B2B and service businesses. Klaviyo's ecommerce data model, Shopify integration, and revenue attribution are unmatched. ActiveCampaign has stronger CRM features and is more versatile for non-ecommerce use cases.

1

Prepare consented data

Confirm collection points, consent language, list hygiene, and the ecommerce or customer events that should inform segmentation.

2

Start with one lifecycle moment

Build a welcome, post-purchase, or re-engagement sequence with clear exclusions, a human review, and a defined customer goal.

3

Improve relevance before volume

Review engagement, unsubscribes, deliverability, and downstream actions before expanding to more segments or channels.
