Editor's Verdict
Editor's VerdictIf you're running an e-commerce store and want to build out sales sequences, upsells, or abandoned cart flows, Klaviyo is the clear pick. Its templates are built from proven e-commerce best practices and it lets you personalize flows directly off customer actions, like abandoned carts or lapsed purchases. That's why every e-commerce operator we know uses it by default.
Loops stands out for its super simple, modern interface and is perfect if you want to avoid clutter, confusing workflows, or bloated pricing. It's especially appealing for SaaS teams or anyone who wants to set up campaigns and sequences quickly, segment audiences without fuss, and just get emails out with minimal overhead. The API is flexible and it's easy to automate from your CRM, so you barely need to touch the app after setup.
If you care most about e-commerce-focused flows, tested templates, and deep behavioral targeting, go with Klaviyo. If you just want something straightforward, clean, and easy for general marketing or SaaS-style automation, Loops is the one you'll actually enjoy using. Both are strong, but each is built with a different primary user in mind, Klaviyo for e-commerce, Loops for those who want simplicity and speed without extra baggage.
