If you sell products online, Klaviyo almost always wins.

Our Verdict

Frequently Asked Questions
Should I switch from Mailchimp to Klaviyo for my Shopify store?
If your Shopify store is generating more than $5,000/month in revenue, almost certainly yes. Klaviyo's abandoned cart flows, post-purchase sequences, and revenue attribution typically deliver 15-30% more email-driven revenue than Mailchimp for e-commerce brands.
Is Klaviyo more expensive than Mailchimp?
At small list sizes, pricing is comparable. Klaviyo can get expensive as your list grows, but the ROI for e-commerce brands typically far exceeds the additional cost. Service businesses are often better served by Mailchimp's lower price.
Is Mailchimp good for e-commerce?
It works, but it's not optimized for e-commerce. Klaviyo, Omnisend, and Drip are all significantly better choices if your primary goal is driving e-commerce revenue through email.
Can Klaviyo do SMS marketing?
Yes — Klaviyo includes SMS marketing that integrates natively with email flows. You can run coordinated email + SMS campaigns (like abandoned cart) from one platform. Mailchimp's SMS capabilities are much more limited.
