Verdict on Mailchimp

Mailchimp is a solid choice for merchants who already know the platform or need a tool that extends beyond Shopify into broader marketing. Its AI features and deliverability reputation are strong assets. However, for a purely Shopify-focused store, ecommerce-native platforms like Klaviyo or Omnisend may offer tighter integrations and better value at scale.
