Omnisend vs Klaviyo Comparison

Selecting the right email marketing service provider hinges on understanding its capabilities.

While both Omnisend and Klaviyo platforms share core functionalities, such as strategic email campaigns and automated customer interactions, their unique offers can significantly impact your choice.

1. Email Deliverability

The success of your email campaigns depends on email deliverability. If your emails don’t reach inboxes, your open rate will suffer, and so will your conversions.

Omnisend and Klaviyo claim to have strong email deliverability results, enjoying a strong reputation for delivering emails effectively. Omnisend has a deliverability rate of 87.9%, with only 1.9% of total emails landing in spam. On the other hand, we don’t have exact numbers for Klaviyo, but they are accessible for the clients individually.

New users typically need to invest time in warming up their domain, building a positive sender reputation, and cleaning their email lists. Both platforms employ industry-standard practices to ensure your emails reach the inbox rather than the spam folder.

2. Analytics

Tracking campaign performance is crucial for optimization.

Omnisend excels at providing a comprehensive overview of both email and SMS campaigns through intuitive dashboards and visual reports. You can also do a deep dive into individual subscriber behavior and purchase history.

Klaviyo takes analytics a step further with predictive capabilities. By forecasting customer behavior and lifetime value, you can tailor campaigns for maximum impact on engagement, retention, and revenue.

Winner: While Omnisend offers strong analytics, Klaviyo is a winner in this area since it provides a deeper level of analysis and insights, particularly for businesses seeking advanced segmentation and predictive capabilities.

3. Segmentation

Email segmentation is a cornerstone of effective email marketing, allowing businesses to divide their audience into smaller, more targeted groups based on shared characteristics or behaviors.

Klaviyo offers advanced segmentation capabilities, allowing you to create virtually unlimited segments based on a wide range of criteria, including predictive analytics data like churn risk and customer lifetime value. This level of sophistication empowers you to create highly targeted campaigns.

Omnisend provides a solid foundation for segmentation, offering pre-built categories like campaign activity, profile data, and shopping behavior. While less complex than Klaviyo, Omnisend’s approach can be effective for businesses new to email marketing.

Winner: Ultimately, the best segmentation tool depends on your experience level, so this is a tie. Beginners might find Omnisend’s guided approach easier to navigate, while experienced marketers will likely appreciate Klaviyo’s flexibility and depth.

These can be customized and triggered based on specific customer actions, such as email opens or clicks. Omnisend also offers a unique advantage with automated web push notifications, expanding your reach beyond email.

While slightly less extensive than Omnisend, Klaviyo’s strength lies in its integration with predictive analytics and segmentation, creating powerful automated customer journeys.

Winner: Both platforms offer solid automation capabilities, but Klaviyo is a winner here. Its integration with its other features gives it a slight edge for creating highly personalized and effective campaigns.

5. SMS Marketing

Both Omnisend and Klaviyo offer comparable SMS marketing features. Users can automate SMS marketing campaigns triggered by specific events, such as order confirmations, and collect customer opt-ins via SMS.

The primary difference lies in geographic reach. Omnisend provides global SMS capabilities, while Klaviyo currently limits SMS to the US, UK, New Zealand, Australia, and Canada.

Winner: For businesses requiring global SMS marketing, Omnisend is the clear choice.

6. Integrations

Both Omnisend and Klaviyo seamlessly integrate with major eCommerce platforms, such as Shopify, BigCommerce, WooCommerce, and Magento. However, their integration capabilities diverge beyond eCommerce.

Omnisend stands out for its extensive integration capabilities, connecting with shipping providers, CRMs, customer support platforms, form builders, and landing page tools. This broader ecosystem makes it a versatile choice for businesses that need to integrate email marketing with other aspects of their operations beyond eCommerce.

Klaviyo excels at deep integrations with eCommerce platforms, allowing for granular data transfer and personalized campaigns based on purchase history. If your primary focus is eCommerce and you need a platform deeply intertwined with your online store, Klaviyo is a strong contender.

While both platforms offer robust integration options, it’s essential to consider your specific business needs.

Winner: This one is a tie. If you require a wide range of connections, Omnisend might be a better fit. For businesses heavily reliant on eCommerce data, Klaviyo’s deeper integrations could be advantageous.

Campaign Refinery offers deeper integrations with email-specific tools, providing more seamless data transfer and functionality with email marketing platforms. Our area of expertise is data-driven integrations, which lets companies use information from different sources for sophisticated segmentation and personalization.

7. A/B Testing

A/B testing is vital for maximizing campaign performance. Both Omnisend and Klaviyo offer A/B testing capabilities but with varying degrees of depth.

Omnisend currently offers very limited A/B testing performance based only on the sender name and subject line, providing relatively basic optimization options.

The number of A/B tests is not limited, allowing for robust optimization across email and SMS channels.

Winner: Klaviyo’s superior A/B testing features make it the preferred choice for businesses seeking advanced testing and optimization.
