Klaviyo migrations
I move your email and SMS marketing to Klaviyo without losing subscribers, unsubscribes, or revenue along the way. Your lists, consent, and suppressions move over cleanly, your flows and templates are recreated properly in Klaviyo, and the switch happens on a planned day, so customers never get two welcome emails or none at all.

Why it matters
Exporting a CSV and importing it into Klaviyo takes ten minutes. That's not a migration. The real work is everything around it: who is allowed to receive email, which flows must keep running, when the old platform stops sending, and how a brand-new sending domain earns trust with Gmail. When those details are rushed, these are the problems I'm usually called in to fix.
What moves and what doesn't
Not everything on your old platform can be exported. Knowing which is which is the first step of a clean migration.
Exported from your old platform and imported into Klaviyo.
Pulled in by Klaviyo's Shopify or WooCommerce integration.
Automations and designs don't transfer between platforms.
Open and click history doesn't transfer. Klaviyo starts with no record of who engaged on your old platform. Before I export, I save each profile's recent engagement as a property, so I can still send to your most engaged people first while the new sending setup warms up.
Translating your setup
Every platform organizes things a little differently. This is how I map what you have today onto Klaviyo.
| On your old platform | In Klaviyo | What I watch for |
|---|---|---|
| Audience or main list | Lists | Usually one main newsletter list, not dozens of old ones |
| Tags and groups | Lists or custom properties | Only the tags you'll actually use for segmenting |
| Automations or journeys | Flows | Triggers, filters, and exits set up the Klaviyo way |
| Segments | Segments | Rebuilt on order and site data, not old open history |
| Popups and embedded forms | Signup forms | The old forms removed so there's never two |
| Merge tags | Template tags | Fallbacks, so no one gets “Hi ,” |
| Unsubscribed and cleaned contacts | Suppressed profiles | Imported before anything is sent |
My process
I list every live flow, form, list, integration, and SMS program on your current platform, and record your email revenue, so we can measure the switch honestly.
I connect Shopify or WooCommerce, sync your order history, and set up a branded sending domain with SPF, DKIM, and DMARC before any email goes out.
Suppressions first, then subscribers with the right consent status, then properties. I leave out bounced, fake, and long-dead addresses instead of carrying them over.
Flows, templates, signup forms, and segments, set up natively in Klaviyo. I don't copy weak flows; I fix them while they're being recreated.
On one planned day, the Klaviyo flows go live and the old ones stop. Forms switch over, and I test everything with real signups and orders.
Campaigns start with your most engaged profiles and widen gradually. Then I compare results against the baseline from phase 1.
Cutover day
The order matters more than the speed. This is the sequence I follow, so there's never a moment when customers get two emails, or none.
Anyone who unsubscribed on the old platform, right up to today.
Signups since the main import, so no one falls through the gap.
Welcome, abandoned checkout, cart, browse, post-purchase, and the rest.
Each old automation stops as its Klaviyo version starts.
Klaviyo signup forms on, old popups and embed codes removed.
A real signup, an abandoned checkout, and a test order, checked end to end.
Once everything has run cleanly in Klaviyo, I remove the old tracking scripts and DNS records, and you can cancel the old subscription.
Deliverability after the move
Gmail and Yahoo know your old sending setup. They don't know Klaviyo's yet. The first weeks after a migration decide whether your emails keep landing in the inbox.
send.yourbrand.comMore on this on my Klaviyo email deliverability page.
Moving SMS
SMS consent is stricter than email consent, so I treat moving SMS as its own project.
I only import SMS subscribers whose consent is documented, with when and where they opted in. A list of phone numbers on its own isn't permission to text anyone.
Your Klaviyo sending number or sender ID has to be set up, and approved where your country requires it, before the first text goes out. I plan the cutover around that.
People who texted STOP on your old platform stay opted out in Klaviyo. I also set up STOP, HELP, and START keywords, quiet hours, and Smart Sending. See my Klaviyo SMS page.
Rules differ by country and state. I follow Klaviyo's tools and recommended practices, but I don't give legal advice. If you're unsure about your SMS consent records, I recommend checking with qualified counsel before importing.
Better, not just moved
You're recreating everything anyway, so I use the move to set up what your old platform was missing.
Where to go next: the flows I usually add are on my Klaviyo flows page. If you're not sure whether to migrate at all, a Klaviyo audit of your current setup is a good first step.
