On the positive side, MailerLite lets you create reusable blocks and save customized templates for future use. But overall template personalization and flexibility are more limited compared to Klaviyo.

Winner: Klaviyo

This MailerLite Klaviyo comparison shows that Klaviyo is the clear winner. With its abundance of customizable, mobile-optimized templates and built-in A/B testing, Klaviyo wins for best email template features.

For users just needing campaign response dashboards, MailerLite reports do the trick. But Klaviyo far surpasses analytics depth and customization for strategic use.

Unique Features


What makes Klaviyo stand out from other email platforms is its Recover Lost Sales tool. This uses real-time analytics tracking to instantly identify users who recently abandoned carts or didn’t complete desired actions on your website.

The goal is to prompt them to complete the purchase and revive those lost sales opportunities, which has delivered game-changing revenue recovery results for many e-commerce merchants.

Additionally, Klaviyo offers fully integrated surveys you can seamlessly drop into emails or web pages. This provides an easy way to gather direct customer feedback through their Profile API, enabling an ongoing two-way conversation that gives insights to continuously refine messaging and campaigns.
