Klaviyo gets used by every e-commerce store owner we talked to because it just works for email flows, while Mailchimp makes basic sending confusing and pushes templates that hurt engagement.
Only use Mailchimp if you have no other choice and want frustration, but Klaviyo is what everyone serious about email marketing actually picks.
If you're running an e-commerce store and want email flows that just work, Klaviyo is the clear pick. It gives you proven templates built for e-commerce, nails the basics like abandoned cart and upsell sequences, and actually helps you personalize and A/B test based on real customer behavior.
Mailchimp, on the other hand, buries you in options and makes even sending a simple email feel like a chore. Its focus on flashy templates actually hurts engagement, and the whole setup gets messy fast if you're just trying to send effective marketing emails.
For e-commerce, Klaviyo isn't just better, it's the default for a reason. Mailchimp only makes sense if you want to get lost in menus and don't care about what actually works for your store. Use Klaviyo and skip the headache.
