Choosing between Mailchimp and Klaviyo shapes how much revenue your store pulls from email and SMS. Mailchimp is the familiar all-purpose tool; Klaviyo is the e-commerce specialist. Here is a clear, unbiased answer for US online sellers.
Key Takeaways
- Klaviyo is purpose-built for e-commerce with deeper Shopify and product-data segmentation.
- Mailchimp is cheaper at low volume and easier for general small-business marketing.
- Klaviyo usually drives more revenue per email through granular automation flows.
- Switching later is possible but migrating flows and segments takes real effort, so choose deliberately.

The Short Answer
If you run a real e-commerce store and care about revenue attribution, Klaviyo is the stronger default. It was built around product catalogs, purchase behavior, and deep store integrations, so its automations and segments tend to convert better. Mailchimp can work, but it treats commerce as one feature among many.
That said, Klaviyo is not automatically the right call. If you are a very small store, a service business, or you value a cheaper, simpler all-in-one tool, Mailchimp is a reasonable and often more affordable pick. The right answer depends on volume, catalog complexity, and how much you lean on email.
- Klaviyo wins for serious Shopify and WooCommerce stores.
- Mailchimp wins for low volume and mixed marketing needs.
- Revenue per email usually favors Klaviyo's segmentation.

Where Each Option Wins
Klaviyo shines on data. It pulls in every order, browse, and product interaction, then lets you build precise segments like repeat buyers of a category who have not purchased in 60 days. Its prebuilt e-commerce flows (abandoned cart, browse abandonment, post-purchase, winback) are strong out of the box, and revenue reporting ties directly to each flow.
Mailchimp wins on breadth and simplicity. It bundles email, basic automation, landing pages, and a friendly editor at a lower entry price. For a small store, a newsletter-led brand, or a business that also needs general marketing, Mailchimp gets you live fast without a steep learning curve.
- Klaviyo: product-level data, granular segments, revenue attribution.
- Mailchimp: lower entry cost, gentle learning curve, broad tooling.
- Klaviyo: native SMS built into the same flows.
Side-by-Side Comparison
The table below compares Mailchimp and Klaviyo on the factors that matter most for an online store. Values reflect typical US pricing and capabilities at the time of writing.
Read it against your own volume and catalog. A pricing edge matters less if the platform leaves revenue on the table through weaker segmentation.
- Compare on your real subscriber count, not a tiny plan.
- Weigh automation depth over template polish.
- Factor in SMS if it is part of your channel mix.
| Factor | Mailchimp | Klaviyo |
|---|---|---|
| Pricing | Lower entry; ~$13/mo starting, cheaper at low volume | Higher; ~$20/mo starting, scales with profiles |
| Performance | Solid deliverability, general-purpose | Strong deliverability tuned for commerce |
| E-commerce data | Basic store connect, limited product data | Deep product, order, and browse data |
| Segmentation | Good, tag and audience based | Excellent, behavior and predictive |
| Automation flows | Decent, fewer commerce templates | Rich prebuilt e-commerce flows |
| SMS | Add-on, less integrated | Native, shares flow logic |
| Best for | Small stores, mixed marketing | Growth-focused e-commerce brands |
| Lock-in | Moderate, exportable data | Moderate, flow rebuild on exit |
How to Choose
Pick Klaviyo if email and SMS are a core revenue channel, you run Shopify or WooCommerce, and you want segmentation and flows to do heavy lifting. Pick Mailchimp if you are early stage, budget-sensitive, or your marketing extends well beyond store sales. Map your monthly send volume and expected revenue per email before deciding.
The common mistake is choosing on sticker price alone. A slightly pricier platform that lifts email revenue 20 percent pays for itself quickly. The other mistake is over-buying Klaviyo for a store with almost no traffic, where its power sits unused.
- Choose Klaviyo when store data drives your campaigns.
- Choose Mailchimp when simplicity and cost lead.
- Estimate revenue per email, not just monthly fees.
