Omnisend is the most common alternative for e-commerce brands leaving Klaviyo. Both platforms are built for online stores, both integrate deeply with Shopify, and both offer email and SMS in one platform. The main reason businesses switch is pricing: Omnisend is significantly cheaper than Klaviyo at most list sizes, particularly once SMS is factored in.
This guide covers everything you need to migrate from Klaviyo to Omnisend without losing subscribers or breaking your automations. Estimated time: 3-6 hours.
What transfers and what does not
| Item | Transfers? | Notes |
|---|---|---|
| Contacts and subscribers | Yes | Via CSV export/import |
| Contact properties | Partial | Standard fields map; custom properties need manual mapping |
| Segments | Partial | Basic list exports; complex segments need to be recreated |
| Suppression list | Yes | Export from Klaviyo, import as suppressed in Omnisend |
| Email templates | No | Must be rebuilt in Omnisend |
| Flows (automations) | No | Must be rebuilt in Omnisend |
| Campaign history | No | Historical stats stay in Klaviyo |
| Shopify integration | Yes | Disconnect Klaviyo, connect Omnisend to Shopify directly |
Keep your Klaviyo account active throughout the migration. Do not cancel it until Omnisend is fully set up and tested. Cancelling early means losing access to your historical data and any active automations still running.
Step-by-step migration guide
Sign up at Omnisend and connect your Shopify or WooCommerce store. Omnisend will begin syncing your store data. Keep Klaviyo running in parallel until Omnisend is fully operational.
Add your domain in Omnisend's sender settings and complete DKIM authentication. Do this before importing contacts or sending any emails.
In Klaviyo, go to Lists and Segments, select your main subscriber list, and export as a CSV. Include all profile properties. Export your suppression list separately.
In Omnisend, go to Audience, Subscribers, and import your CSV. Map fields carefully. Import suppressed contacts as unsubscribed to maintain compliance. Your Shopify-connected contacts will also sync automatically.
This is the main rebuild work. Document your active Klaviyo flows before starting. In Omnisend, go to Automation and rebuild each flow. Omnisend has a pre-built library of e-commerce flows (welcome series, cart abandonment, browse abandonment, post-purchase) that you can customize rather than building from scratch. This speeds up the process significantly.
Use Omnisend's drag-and-drop editor to rebuild your key templates. Omnisend's email builder includes dynamic product blocks that pull in your store's product data automatically.
Recreate your opt-in forms in Omnisend. Replace Klaviyo form scripts on your website with Omnisend embeds. Test each form.
Once Omnisend is fully tested and operational, remove the Klaviyo integration from your Shopify store. This prevents duplicate data sync. Cancel Klaviyo on your billing date.
The bottom line
Migrating from Klaviyo to Omnisend is a like-for-like move between two e-commerce-focused platforms. Omnisend's pre-built automation library speeds up the workflow rebuild considerably. Budget three to six hours for the migration and run both platforms in parallel for a few days before fully switching.
