Choosing the right email marketing platform can make or break your ecommerce growth strategy. In 2025, two of the top contenders for ecommerce brands are Omnisend and Klaviyo both powerful tools with automation, segmentation, and revenue-driving features. But which one is better for your business?
In this balanced comparison, we’ll break down:
- Features
- Pricing
- Ease of use
- Automation capabilities
- Integrations
- Support
- Overall value
And while both platforms are robust, Omnisend is the clear winner for brands that want high performance without breaking the bank.
Feature Comparison: Email, SMS & More
Omnisend:
✅ Email + SMS + Push notifications all in one platform
✅ Pre-built automation workflows (welcome, cart, browse, winback, etc.)
✅ Drag-and-drop builder
✅ Product recommender blocks
✅ Gamified popups (e.g., spin-to-win)
✅ Channel flexibility (email, SMS, push)
Klaviyo:
✅ Deep email and SMS automation
✅ Powerful segmentation tools
✅ Dynamic content blocks
✅ AI-generated subject lines
❌ No native push notifications
❌ SMS is paid separately (no free credits)
Both platforms have top-tier features. Klaviyo wins on advanced segmentation, but Omnisend provides a more complete multichannel solution out of the box, especially with native push and gamified forms.
Pricing: Affordability at Scale
Omnisend Pricing (2025):
- Free Plan: Up to 250 contacts, 500 emails/month
- Standard Plan: From $16/month (includes 6,000 emails/month + SMS credits)
- Pro Plan: From $59/month (includes 24/7 support + advanced reporting)
Klaviyo Pricing (2025):
- Free Plan: Up to 250 contacts, 500 emails/month
- Email Plan: Starts at $45/month for 1,001–1,500 contacts
- Email + SMS Plan: Pricing scales rapidly with contact count and SMS volume
Omnisend is more affordable, especially for growing brands with larger contact lists or multichannel strategies. Klaviyo’s pricing scales steeply and charges extra for SMS.
Ease of Use: Setup, Templates & Interface
Omnisend:
✅ Clean, user-friendly interface
✅ 20+ pre-built automation workflows
✅ Easy drag-and-drop email builder
✅ Beginner-friendly templates and forms
Klaviyo:
✅ Slick UI for advanced users
✅ Steeper learning curve for new users
✅ Automation builder is powerful, but less intuitive
✅ Form builder feels outdated compared to Omnisend
Omnisend is easier to launch with, especially if you’re a small team or just getting started with automation. Klaviyo is great but may require more setup time and experience.
Automation Capabilities: Personalisation at Scale
Omnisend:
✅ Ecommerce-focused prebuilt workflows (cart, browse, welcome, birthday, winback)
✅ SMS + email + push in one flow
✅ Conditional splits based on product, behaviour, order value
✅ Dynamic discount blocks
✅ Automation templates save time
Klaviyo:
✅ Advanced custom workflows
✅ Behavior-based triggers
✅ Complex branching logic
✅ Predictive analytics for churn/lifetime value
❌ Requires more setup for multi-channel flows
Klaviyo is powerful for complex segmentation and big-data workflows. But Omnisend gets you 80% of the performance with 20% of the effort, thanks to ecommerce-ready automation templates.
Segmentation & Personalisation
Omnisend:
✅ Segments based on purchase history, behaviour, location
✅ Sync segments across email/SMS/push
✅ Product-based dynamic content
✅ Built-in A/B testing
Klaviyo:
✅ Highly advanced segmentation logic
✅ Predictive segments (e.g. likely to buy again)
✅ Real-time data syncing with ecommerce platforms
✅ Custom property-based personalisation
Klaviyo leads here with predictive segmentation, ideal for advanced marketers. However, Omnisend offers powerful, practical segmentation tools that are more than enough for 95% of ecommerce brands.
Integrations with Ecommerce Platforms
Omnisend:
✅ Deep integrations with Shopify, BigCommerce, WooCommerce, Wix
✅ One-click Shopify sync
✅ Supports global platforms and marketplaces
Klaviyo:
✅ Native integrations with Shopify, Shopify Plus, BigCommerce
✅ Data-rich Shopify integration (e.g., LTV, product metrics)
✅ Built-in CDP-like functionality for larger stores
Klaviyo shines for enterprise Shopify stores. But Omnisend’s Shopify integration is seamless and more than sufficient for DTC and mid-sized brands.
Customer Support & Resources
Omnisend:
✅ 24/7 live chat support (even on Pro plans)
✅ Fast response times
✅ Help centre + ecommerce growth academy
✅ Free migration support
Klaviyo:
❌ No 24/7 support unless on higher-tier plans
❌ Slower ticket-based system for smaller plans
✅ Robust help docs and community forum
Omnisend wins with proactive support for growing brands. Their support team is responsive, helpful, and available even for smaller clients.
Performance & ROI
According to Omnisend’s 2025 benchmarks:
- Omnisend automation emails drive 32% of total email revenue on average
- SMS campaigns see 19.1% click-through rates
- Brands using both email + SMS see 47.7% higher conversion rates
Meanwhile, Klaviyo also boasts strong numbers especially for larger brands with high list segmentation sophistication. But their best performance is typically seen after deep setup and strategy refinement.
Omnisend delivers faster ROI and easier wins for brands focused on efficiency and lean growth.
