MailerLite vs Klaviyo: general email tool or store-data engine

The practical difference

Both send email to online shoppers and connect to the main store platforms. As read on October 6, 2026, Klaviyo's free plan is limited to 250 active profiles, meaning contacts who may receive marketing email, and 500 email sends a month, and it includes text messages, a Customer Hub and built-in reporting. MailerLite's Free plan allows 250 subscribers and 2,500 emails a month.

Store data and triggers

MailerLite builds its own Shopify app and WooCommerce plugin, and its e-commerce triggers are on every plan: Abandoned cart, Abandoned checkout, Buys any product, Buys specific product, Buys from category and Purchase frequency. Shopify supports every trigger except Abandoned cart, and an e-commerce automation fires only for customers who subscribed and accepted marketing.

Klaviyo says it integrates with major e-commerce platforms and gives segmentation and automation even on its free plan.

Free plan limits and support

Klaviyo's free plan includes email support for the first 60 days after sign-up, and past its limits it stops sending until the next billing cycle or an upgrade. MailerLite Free has community support, with live chat for every account's first 14 days; past 250 subscribers, campaigns and automations pause until you upgrade or trim the list.

Paid plans

Billed monthly at 1,000 subscribers, MailerLite Comfort is $19 a month and Power $39; at 10,000 they are $89 and $129. Klaviyo's paid prices are not given here: check its pricing page at your list size.

Moving a store list

From another platform, MailerLite's help says to export a CSV and import only people who opted in, leaving unsubscribed, spam-complaint and inactive people behind. Store customers also need to accept marketing before MailerLite's e-commerce automations reach them.

Which option should you choose?

Choose Klaviyo if text messages and store-driven automation are the core of your marketing and 500 free sends a month are enough while you test. Choose MailerLite if you want 2,500 free emails a month, a website and landing pages in the same account, and e-commerce triggers on every plan.
