Klaviyo vs Mailchimp: Feature Comparison

For buyers comparing Klaviyo vs Mailchimp, the clearest difference is breadth around customer data and B2C CRM versus broader all-around marketing tooling for many business types.

Klaviyo vs Mailchimp Pricing

Klaviyo is the easier one to evaluate on entry pricing because its tiers and included usage are clearly defined. Mailchimp presents a broad platform and integrations ecosystem, but the pricing details here are less concrete than Klaviyo’s plan structure.

Klaviyo’s pricing creates a straightforward upgrade path: free for early testing, $45 per month for email-centric teams, and $60 per month for combined email and SMS execution. For businesses that want both channels from the start, that puts Klaviyo’s email-plus-SMS entry point just $15 above its email-only plan.
