The Bottom Line
Klaviyo is the best email and SMS marketing platform available for e-commerce brands, period. It earned a Gold tier rating because no other platform matches its native Shopify integration, revenue attribution accuracy, or e-commerce-specific automation flows like abandoned cart, browse abandonment, and winback sequences. If you sell physical or digital products online and want to know exactly how much revenue every email generates, Klaviyo is the answer.
What is Klaviyo?
Founded in 2012 and headquartered in Boston, MA, Klaviyo went public in 2023 and now serves over 130,000 brands worldwide. It was purpose-built for direct-to-consumer and e-commerce businesses, with Shopify integration so deep that Shopify itself invested in and distributes the platform. Klaviyo is the dominant choice for DTC brands across all major e-commerce platforms.
What does Klaviyo offer?
Klaviyo offers a free plan for up to 250 contacts with 500 sends per month. Paid email plans start at $45/month scaling with contact count, and Email + SMS bundles start at $60/month. Every plan includes the full automation builder, revenue attribution dashboard, predictive analytics, and native integrations with Shopify, BigCommerce, and WooCommerce. Pre-built e-commerce flows (abandoned cart, winback, post-purchase) are included on all plans.

How We Test Email Marketing Software
We test each platform by building an actual campaign from scratch in a fresh account — not by reading documentation or inspecting marketing copy. Deliverability is measured by sending test campaigns to a seed list covering Gmail, Yahoo, Outlook, and Apple Mail inboxes and recording inbox vs. spam placement rate. We build a 5-step automated welcome sequence on each platform and time configuration from start to first test execution. List import is tested with a 1,000-contact CSV, documenting error handling and field mapping quality. Automation accuracy is verified by triggering every branch condition and logging failures. Support is tested by submitting a technical question and measuring first response time and resolution quality. Pricing is captured at checkout — including list size limits and feature restrictions that apply at the stated plan price.
