anitaherbert.com review for Klaviyo: Email Marketing & SMS
Jan. 20, 2026
Klaviyo is hands-down one of the most powerful email and SMS platforms out there for ecommerce. The depth of their analytics is where they really shine. From revenue attribution to flow-level performance and segmentation insights, Klaviyo gives you the kind of data that actually helps you make smarter decisions and squeeze more sales out of every campaign. The segmentation and automation capabilities are excellent, and once you know your way around the platform, it becomes a serious growth engine. If you care about understanding customer behavior and optimizing lifecycle marketing, Klaviyo is hard to beat. That said, pricing is the biggest downside. Being charged for all profiles in your account—even ones you never email—can feel frustrating, especially for growing brands with large lists. It would be much more fair (and sustainable) if pricing were based only on the profiles you actively send emails to. Overall, Klaviyo is an elite tool with best-in-class data and performance. If they adjusted their pricing model to better reflect actual usage, it would be close to perfect.
Thank you for the thoughtful, 5 star review! We're really happy to hear that you're seeing value in Klaviyo analytics, and that the data we provide is helping your business grow. Understanding your customers is incredibly important, and we're glad that we can help you do so! We appreciate the feedback regarding pricing. Klaviyo bills based on active profiles, and we encourage you to suppress profiles that you don't plan on sending emails to. You keep suppressed profiles' data, but since they're unable to receive emails, you do not need to pay for them, and they do not count towards your active profile limit. We encourage you to reach out to our support team, and we can help you suppress profiles, which will in turn help save on your plan!
