Klaviyo and MailerLite are not really competing for the same customer. Klaviyo is built for e-commerce businesses that want deep Shopify integration, revenue attribution, and behavioral segmentation based on purchasing behavior. MailerLite is a lean, affordable tool for bloggers, creators, and small businesses running standard email programs.
If you run an online store, Klaviyo is probably the more appropriate tool. If you do not, MailerLite gives you everything you need at a fraction of the cost.

E-commerce vs general purpose
Klaviyo is purpose-built for e-commerce. Its data model is built around customer behavior: what people buy, browse, abandon, and return to purchase. This lets you build highly targeted campaigns based on real purchasing intent. The Shopify integration pulls in granular store data automatically.
MailerLite is a general-purpose email tool. It has Shopify and WooCommerce integrations, but the level of e-commerce intelligence is much shallower. For online stores, Klaviyo's advantage here is substantial.
Pricing
MailerLite is significantly cheaper. At 5,000 subscribers, MailerLite costs around $18/mo while Klaviyo jumps to $100/mo or more. Klaviyo's pricing is justified by its e-commerce revenue tracking, but it is only worth paying if you are actually an e-commerce business benefiting from those features.
For non-e-commerce use cases, paying Klaviyo rates makes little sense.
Ease of use
MailerLite is one of the most beginner-friendly tools available. Klaviyo's interface is data-dense and can be overwhelming for new users. It has a steeper learning curve that is worth the investment for e-commerce businesses, but not for those who do not need the depth.
Choose Klaviyo if...
- You run an online store, especially on Shopify
- Revenue attribution and e-commerce segmentation matter to you
- You send SMS alongside email and want them in the same platform
- You need advanced behavioral segmentation based on purchase history
Choose MailerLite if...
- You are not in e-commerce
- Budget is a primary consideration
- You want the simplest, most beginner-friendly experience
- Email, automation, and landing pages cover your needs
The bottom line
Klaviyo is the right choice for e-commerce businesses that will actually use its store data features. For everyone else, MailerLite gives you strong email capability at a fraction of the price.
