Switching to Klaviyo and Terrified of Losing Your List?
A bad migration means duplicate emails, broken automations, and burned subscribers. I've seen it happen. I make sure it doesn't happen to you.
Hi, I'm Samuel. I specialize in clean, zero-data-loss migrations from Mailchimp, ActiveCampaign, Omnisend, and other platforms into Klaviyo with all your flows, segments, and history intact.
What I Migrate:
- Full contact list with properties and tags
- Unsubscribes and suppression lists

- Existing automation flows rebuilt in Klaviyo
- Email templates recreated in Klaviyo editor

FAQ
Will my contacts lose their history or tags?
No. I map all existing properties, tags, and custom fields to Klaviyo's profile system before migrating.
What happens to my unsubscribers?
Unsubscribers are migrated to Klaviyo's suppression list first — before any contacts — so no one gets re-emailed accidentally.
Should I keep my old platform running during migration?
Yes, until I confirm everything is live and tested in Klaviyo. I'll tell you exactly when to turn it off.
Can you migrate my automation sequences too?
Yes. Standard and Premium packages include rebuilding your key flows inside Klaviyo with the same triggers and timing logic.
What platforms can you migrate from?
Mailchimp, ActiveCampaign, Omnisend, Drip, Klaviyo (account-to-account), ConvertKit, and Brevo. Ask if yours isn't listed.
Will my email templates look the same in Klaviyo?
Templates are rebuilt in Klaviyo's editor — not copy-pasted. They'll be cleaner and optimized for Klaviyo rendering.
Do you handle Shopify re-integration after migration?
Yes. After migration, I reconnect Klaviyo to your Shopify store so all events and purchase data flow correctly.
How long does a full migration take?
Basic list transfer: 1–2 days. Full migration with flows: 4–5 days. Complex setups with large lists may take longer.
What if I have a massive list (100k+)?
Large lists need special handling. Message me before ordering and I'll confirm the approach and timeline.
Can you clean my list before migrating?
Yes. List cleaning (removing bounces, unengaged contacts) can be added as an extra — highly recommended before moving platforms.
