Klaviyo and Mailchimp Overlap: Do You Need Both?
Email marketing overlap. Klaviyo is purpose-built for e-commerce; Mailchimp is more general.
Side-by-side snapshot
| Tool | Score | Category | Top strength | Honest risk | Pricing signal |
|---|---|---|---|---|---|
| Klaviyo | 60Average | E-commerce marketing automation | Deepest Shopify integration in the category | Pricing scales aggressively with active profiles — surprise bills are common | Tiered by active profiles and SMS credits — typical SMB stores land $45–$300/mo for email-only, with SMS layered on top. Enterprise pricing custom and commonly low-five figures monthly. |
| Mailchimp | 77Strong | Email & audience marketing | Very approachable for non-enterprise marketers | Less suited to complex enterprise lifecycle architecture | Tiered by audience size; generous free tier historically — paid plans scale with contacts and feature bundles.. |
Which one should you keep?
- Keep Klaviyo if: DTC or ecommerce brand on Shopify/BigCommerce.
- Keep Mailchimp if: SMB motion with email-first marketing and minimal ops overhead.
- Keep both only if: you're mid-migration with a fixed consolidation deadline inside 90 days. Long-term, the duplicated contract value ($720/yr on modeled averages) almost always outweighs the feature overlap justification.
Where each wastes money
- Klaviyo: Klaviyo overlaps with Customer.io, Iterable, Braze, Mailchimp, and HubSpot. The DTC waste pattern is Klaviyo + a separate SMS tool (Postscript, Attentive) when Klaviyo SMS would cover it — or Klaviyo + Mailchimp when teams "graduated" but never turned off the old contract.
- Mailchimp: Mailchimp overlaps ActiveCampaign and HubSpot marketing features when teams "graduate" but never turn off the old tool.
