Mailchimp vs Klaviyo vs Postscript for Shopify stores boils down to three distinct approaches to marketing automation. Mailchimp is a generalist email marketing platform with ecommerce features, Klaviyo offers deep Shopify-centric email and SMS automation with advanced customer insights, and Postscript focuses exclusively on SMS marketing designed for Shopify merchants. Each has advantages and trade-offs depending on store size, budget, and marketing priorities.
Core features and functionality comparison
| Feature | Mailchimp | Klaviyo | Postscript |
|---|---|---|---|
| Email Marketing | Yes, full suite | Yes, with advanced segmentation | No |
| SMS Marketing | Limited, via integrations | Included, integrated with email | Yes, SMS-focused |
| Automation Workflows | Basic to intermediate | Sophisticated, event & behavior-based | SMS-centric flows |
| Customer Data & Segmentation | Basic segmentation | Deep customer profiles, Shopify data | Limited segmentation |
| Shopify Integration | Available but limited | Native, very strong | Native, built specifically for Shopify |
| Reporting & Analytics | Standard email metrics | Advanced, multi-channel | SMS analytics |
| Personalization | Basic merge tags | Dynamic content, predictive analytics | SMS personalization |
Mailchimp provides a solid, easy-to-use platform for email campaigns and basic automation but lacks advanced ecommerce features. Klaviyo marries email and SMS with powerful Shopify customer data access and complex automation. Postscript focuses on SMS as a primary channel with Shopify-optimized flows but no email marketing.
Pricing and value
| Pricing Tier | Mailchimp | Klaviyo | Postscript |
|---|---|---|---|
| Free Tier | Up to 500 contacts, limited features | Up to 250 contacts, email only | No free tier |
| Entry Paid Plan | Starting around $13/month for 500 contacts | Starting around $20/month for 500 contacts | Starting at $25/month + per SMS fees |
| Mid-Tier Example | $59/month for 2,500 contacts | $150/month for 2,500 contacts (email + SMS) | ~$150+/month depending on SMS volume |
| Pricing Notes | Email focused, pay by contacts | Email + SMS, pay by contacts + volume | SMS volume has variable costs |
Mailchimp is generally cheapest for basic email marketing but adds cost as contact lists grow. Klaviyo can be pricier but includes SMS and more powerful features. Postscript's SMS pricing is separate and can escalate based on message volume, making it costlier for stores reliant on heavy texting.
Ease of setup and use
Mailchimp has a clear, intuitive interface designed for marketers without technical expertise. Setting up email campaigns and templates is straightforward. Shopify integration requires third-party connectors and can be clunky.
Klaviyo’s setup is more complex due to deep Shopify integration and advanced options. Users need some familiarity with ecommerce marketing to get full value. Its interface is well designed but layered.
Postscript offers a Shopify app with a simple setup focused on SMS opt-ins and campaigns. It’s easier to implement quickly but limited in scope.
Integrations
| Integration Type | Mailchimp | Klaviyo | Postscript |
|---|---|---|---|
| Shopify | Via third-party connector | Native, deep API-based integration | Native, built for Shopify |
| Other eCommerce Platforms | Yes (WooCommerce, Magento) | Limited outside Shopify and BigCommerce | No |
| Marketing Channels | Email, social ads integrations | Email, SMS, Facebook, Instagram, ads | SMS only |
| CRM/Other Tools | Zapier, Salesforce, etc. | Zapier, custom APIs | Limited |
Klaviyo wins easily for Shopify integration depth. Mailchimp’s Shopify connection is functional but limited. Postscript is purpose-built for Shopify and SMS, without broader platform support.

Mailchimp offers email and chat support, extensive online resources, and a large user community. Response times vary at lower pricing tiers.
Klaviyo provides email, chat, and phone support for higher tiers. Its documentation is thorough, especially around ecommerce use cases.
Postscript focuses on chat and email support with Shopify store experience. Documentation is solid but narrower in scope.
Best-fit customer profiles
