Omnisend and Klaviyo are both built specifically for e-commerce and both are excellent. They are not general email marketing tools that happen to support Shopify, they are platforms designed from the ground up around the e-commerce use case.

Klaviyo is considered the gold standard for data-driven e-commerce email and SMS. Omnisend is the more affordable alternative that covers most of the same ground for stores that do not need Klaviyo's analytical depth.

Pricing

Both have free plans capped at 250 contacts. Omnisend's paid plans start slightly lower and tend to be cheaper at comparable tiers. Klaviyo gets expensive quickly as your list grows, which is one of the most common reasons stores consider switching to Omnisend.

Shopify integration

Both integrate deeply with Shopify. Klaviyo's integration is widely considered the best available, the data it pulls from Shopify and how it uses that data for segmentation and personalization is exceptional. Omnisend's integration is strong and covers all the standard triggers and actions.

Analytics and attribution

This is where Klaviyo truly separates itself. Its revenue attribution, customer lifetime value reporting, and predictive analytics are best in class. If you make data-driven decisions and want to understand exactly what your email program is worth in dollar terms, Klaviyo's reporting is unmatched at this price point.

Omnisend's analytics are solid and covers what most stores need. But if you want the deepest data, Klaviyo wins.

Ease of use

Both have a moderate learning curve. Omnisend is generally considered slightly easier to set up and configure. Klaviyo's depth means there is more to learn before you can use it fully.

Choose Omnisend if...

  • You want strong e-commerce automation at a lower price point
  • Klaviyo's pricing has become too expensive as your list grows
  • You want email and SMS in one tool without paying Klaviyo prices
