An online course creator messaged me asking if they should switch from MailerLite to Klaviyo. My first question was: do you sell physical products? They didn’t. And that pretty much answered the question. MailerLite and Klaviyo exist in different orbits. MailerLite is a straightforward newsletter tool that happens to be excellent at what it does. Klaviyo is a data-intensive ecommerce machine. If you’re not running a store, Klaviyo’s advanced features are wasted. But if you are, MailerLite will hold you back.
When MailerLite wins
MailerLite is the best value in email marketing, period. For $10 a month you get unlimited sends to 1,000 subscribers, a genuinely excellent drag-and-drop editor, basic automation, landing pages, and a clean interface that doesn’t overwhelm you. For creators, bloggers, course sellers, and service providers who mainly send newsletters and simple broadcast emails, MailerLite is perfect. I’ve used it for a few of my own projects and never felt limited by the features. The deliverability is solid too — I’ve had better open rates on MailerLite than on much more expensive tools. Klaviyo’s minimum plan starts at $20 for 500 contacts, and you’re paying for features you’ll never use if you don’t have products to sell.
When Klaviyo wins
Klaviyo is built for stores. If you run a Shopify or WooCommerce shop, Klaviyo syncs your product catalog, customer purchase history, and browsing behavior the second you connect it. You can segment customers by lifetime value, product affinity, or predicted churn risk. The abandoned cart flows, post-purchase sequences, and product recommendation emails are pre-built and proven to drive revenue. MailerLite can’t do any of this out of the box — you’d need to manually export purchase data, upload CSV files, and build segments by hand. Klaviyo’s revenue attribution reports also show exactly how much money each flow and campaign brings in, which makes budget approvals easy.
The real deciding factor
The dividing line is simple: do you sell physical or digital products through an online store? If yes, Klaviyo’s product data integration will directly increase your revenue. If no — if you’re a blogger, coach, consultant, or service provider — MailerLite gives you everything you need at a fraction of the price. I’ve seen creators overspend on Klaviyo for years without using any of its ecommerce features. Don’t be that person.
| Feature | MailerLite | Klaviyo |
|---|---|---|
| Best for | Creators, bloggers, small teams | Ecommerce and retail brands |
| Ecommerce features | None native | Full product data integration |
| Automation | Simple triggers and sequences | Purchase-based flows, predictive |
| Email editor | Excellent drag-and-drop | Good but block-based |
| Pricing range | $10–$80/mo (contacts based) | $20–$600+/mo (contacts + emails) |
| Ease of use | Very easy | Moderate |
My honest take? If you have an online store, use Klaviyo. It’s not even close — the product data integration alone is worth the switch. If you don’t have a store, save your money and use MailerLite. It’s one of the few tools I recommend without hesitation for non-ecommerce businesses. Use what fits your actual business model.
