Omnisend vs Mailchimp: Best for Ecommerce in 2026
Omnisend vs Mailchimp for ecommerce: honest comparison of automation, SMS, pricing, and Shopify integration to pick the right tool.
If you’re selling online and choosing between Omnisend and Mailchimp, the decision comes down to one question: do you want a tool built specifically for ecommerce, or a general-purpose email platform that happens to work with Shopify?
Both send emails. Both have automations. Both integrate with major ecommerce platforms. But the differences underneath are significant — and they compound over time as your store grows.
Here’s an honest breakdown based on running stores on both platforms.
Core Philosophy Difference
Omnisend was built for ecommerce from day one. Every feature — pre-built automation workflows, product picker, scratch cards, gift boxes, push notifications — exists to drive online store revenue.
Mailchimp started as a newsletter tool for anyone, then added ecommerce features over time. It works for restaurants, gyms, bloggers, and stores alike. That breadth comes with tradeoffs in depth.
This philosophical difference shows up everywhere.
Automation: The Biggest Gap
Omnisend’s Pre-Built Ecommerce Workflows
Omnisend ships with automation templates designed specifically for online stores:
- Welcome series with discount code generation
- Abandoned cart with product image pull-through from your store
- Browse abandonment targeting people who viewed products but didn’t add to cart
- Post-purchase cross-sell sequences
- Win-back campaigns for lapsed customers
- Order confirmation and shipping notification flows
These work out of the box. You connect your Shopify store, enable the workflow, and Omnisend auto-populates product images, names, and prices from your catalog. No manual setup per product.
The automation builder also supports custom workflows with conditional splits, time delays, and channel switching (email → SMS → push). You can create “if customer hasn’t opened email in 2 hours, send SMS” logic without duct-taping integrations together.
Mailchimp’s Customer Journey Builder
Mailchimp’s Customer Journey feature replaced their older automation system. It’s more visual and flexible than before, but ecommerce-specific workflows require more manual configuration.
Abandoned cart automation exists, but product images don’t pull through automatically — you need to use merge tags and template them yourself. Browse abandonment automation isn’t a pre-built option; you’d need to create it from scratch using segment triggers.
For standard welcome series and basic abandoned cart, Mailchimp works fine. For the full suite of ecommerce triggers that actually convert, Omnisend is significantly faster to deploy and more capable out of the box.
Winner: Omnisend, by a meaningful margin.
SMS and Push Notifications
Omnisend
Omnisend includes SMS and web push notifications in all paid plans. You can mix channels inside a single automation — an email, followed by an SMS if unopened, followed by a push notification. No extra integrations needed.
SMS pricing is included in your plan’s message allocation. The Standard plan ($16/mo for 500 contacts) includes 60 SMS credits. Additional credits cost around $0.01 per US message.
Web push is unlimited and free on all plans.
Mailchimp
Mailchimp added SMS in 2024, but it’s limited. You can send SMS campaigns, but you can’t mix SMS and email in the same automation workflow without workarounds. Push notifications aren’t available at all.
If multichannel marketing matters to your store, this is a clear differentiator. Omnisend treats email, SMS, and push as equals in the same workflow. Mailchimp treats email as primary and SMS as a separate channel.
Winner: Omnisend.
Email Design and Templates
This is where Mailchimp fights back.
Mailchimp’s Builder
Mailchimp’s drag-and-drop editor is arguably the most polished in the email marketing space. The template library is enormous (100+ free templates), responsive design works reliably, and the creative assistant can generate starter designs based on your brand colors.
Custom coding emails is straightforward with Mailchimp’s template language, and the preview across devices is reliable.
Omnisend’s Builder
Omnisend’s editor is good but not as refined. The template library is smaller, though the ecommerce-specific templates (product grids, discount blocks, gift card designs) are more practical for stores.
Where Omnisend shines is the product picker — a block that lets you select products from your connected store and automatically display them with images, names, prices, and “Shop Now” buttons. This alone saves significant time on promotional emails.
Winner: Tie. Mailchimp wins on polish and variety. Omnisend wins on ecommerce-specific productivity.
Pricing Comparison (2026)
| Contacts | Omnisend Standard | Mailchimp Standard |
|---|---|---|
| 500 | $16/mo | $20/mo |
| 2,500 | $40/mo | $55/mo |
| 5,000 | $60/mo | $90/mo |
| 10,000 | $110/mo | $145/mo |
| 25,000 | $250/mo | $350/mo |
Omnisend is cheaper at every tier, and its Standard plan includes SMS credits and push notifications. Mailchimp’s Standard plan doesn’t include SMS.
Important caveat: Mailchimp charges based on total contacts in your audience. Omnisend charges based on “subscribed contacts” — people who are actively opted in. If you have a large list of unsubscribed or cleaned contacts, Omnisend is even cheaper relative to Mailchimp.
Winner: Omnisend.
Integrations and Ecosystem
Mailchimp
Mailchimp integrates with 300+ tools. If you need to connect to a CRM, accounting software, landing page builder, or social platform, Mailchimp probably has a native integration or a Zapier connector.
For non-ecommerce businesses, this ecosystem advantage is significant.
Omnisend
Omnisend integrates with Shopify, WooCommerce, BigCommerce, Wix, and a handful of other ecommerce platforms. Their integration list is narrower — around 40 integrations — but they cover the tools ecommerce stores actually use: Yotpo, LoyaltyLion, Recharge, Gorgias, and Attentive.
If you’re a Shopify store running standard ecommerce tools, Omnisend covers your needs. If you need broader ecosystem connectivity (for non-store tools like HubSpot CRM or Eventbrite), Mailchimp is stronger.
Winner: Mailchimp for breadth. Omnisend for ecommerce depth.
Reporting and Analytics
Omnisend provides revenue attribution that ties email/SMS/push campaigns directly to store purchases. You can see which automation workflow generated the most revenue, which products are driving clicks, and what your revenue per contact looks like.
Mailchimp’s reporting covers standard email metrics (opens, clicks, bounces) and includes basic ecommerce revenue tracking via the Shopify integration. But the attribution isn’t as granular, and you can’t easily compare revenue across channels (email vs SMS) since SMS reporting is separate.
Winner: Omnisend.
The Verdict
| Category | Winner |
|---|---|
| Ecommerce automation | Omnisend |
| SMS + Push | Omnisend |
| Email design | Mailchimp |
| Pricing | Omnisend |
| Integrations | Mailchimp |
| Reporting | Omnisend |
Choose Omnisend if: You run an ecommerce store and want built-in, channel-mixing automations that drive revenue out of the box. It’s the purpose-built choice, and it shows.
Choose Mailchimp if: You need a general-purpose email tool that handles newsletters, non-ecommerce automations, and a wider integration ecosystem. Or if email design quality is your top priority.
For most online stores, Omnisend delivers more ecommerce value per dollar. But if you’re also running non-store email campaigns (events, content marketing, local business), Mailchimp’s flexibility might be worth the premium.
Also consider Brevo if you need transactional email alongside marketing — it’s a strong alternative to both.

FAQ
Can I switch from Mailchimp to Omnisend without losing data? Yes. Omnisend imports contacts, segments, and templates from Mailchimp. Your automation workflows will need to be rebuilt, but Omnisend’s pre-built ecommerce flows make this faster than starting from scratch.
Does Omnisend work with WooCommerce? Yes, there’s a native WooCommerce plugin. The Shopify integration is deeper (supports more event triggers like “product viewed”), but WooCommerce covers core ecommerce automations.
Which platform is better for SMS marketing? Omnisend. It includes SMS in workflows, provides SMS credits in every plan, and lets you mix email and SMS in the same automation. Mailchimp added SMS but it’s a separate channel, not integrated into the automation builder.
Is Omnisend’s free plan useful? Omnisend’s free plan includes up to 250 contacts, 500 emails/month, and basic automation. It’s enough to test the platform, but the 500-email limit is tight. Mailchimp’s free plan (500 contacts, 1,000 sends) gives more room but doesn’t include ecommerce automations.
What about Klaviyo? Klaviyo is the other major ecommerce email player — more powerful than both for advanced segmentation, but significantly more expensive at scale. For stores under 10K contacts, Omnisend typically offers better value. For a full tool comparison, see our best marketing automation tools guide.
