Klaviyo vs Omnisend.

Klaviyo and Omnisend are both ecommerce-first, so the choice is about depth versus simplicity. Klaviyo tends to offer more granular segmentation and a larger ecosystem, while Omnisend is often praised for getting multichannel campaigns running quickly. Compare current features against your team's skills, not against a checklist.

Klaviyo suits you if.

Omnisend suits you if.

Our view.

There is no dramatic gap here. Both understand carts, products and orders. The differences are in how far you can bend the tool: Klaviyo gives more room to build unusual segments, Omnisend gives a smoother path to a working multichannel setup.

Disclosure: Inferno Emails builds in Klaviyo, so weigh our view accordingly. If your programme is straightforward and your team is small, Omnisend may be perfectly enough. Check current features, regions and plans on both sites.

Moving from Omnisend to Klaviyo.

  1. Export contacts from Omnisend including channel consent, because email and SMS permissions must carry across correctly.
  2. Connect your store to Klaviyo and let order history sync first.
  3. Import contacts and recreate the segments you rely on, using store events rather than copied tags where possible.
  4. Rebuild your automations in priority order, starting with welcome and abandoned cart.
  5. Update signup forms to point at Klaviyo, then retire the Omnisend forms and workflows.

Plans, features and limits change often. Check each vendor's current documentation before you decide.
