HubSpot to Klaviyo Migration, Without Breaking Your CRM
Moving ecommerce email from HubSpot to Klaviyo usually means splitting the job, not replacing HubSpot. Ecommerce workflows are rebuilt as Klaviyo flows, buyers and subscribers move across with their consent, and the sales pipeline stays in HubSpot so your sales team never notices the switch. Klaviyo has no built-in HubSpot integration, so we set up the bridge between the two (a partner app from HubSpot's marketplace, Zapier or Make, or a custom API build) and test which data flows which way before cutover. A typical move takes 3-4 weeks.

Why brands move from HubSpot to Klaviyo.
Billing on profiles you can email
HubSpot bills on marketing contacts. Klaviyo bills on active profiles and skips suppressed ones. Which works out cheaper depends on your counts on each side, so we model both on your real numbers in the audit.
Native ecommerce integration
Klaviyo natively integrates with Shopify, BigCommerce, WooCommerce. HubSpot integrates but typically requires custom development for full event-stream sync.
Predictive analytics and ecommerce-specific reporting
Predicted CLV, predicted churn, attributed revenue per recipient, native to Klaviyo, not HubSpot.
Hybrid approach: keep HubSpot CRM, move email to Klaviyo
Most ecommerce brands run this way: HubSpot for sales/CRM/B2B, Klaviyo for ecommerce email/SMS. We integrate the two so contact data flows correctly between systems.
/ What breaks in bad migrations
Where DIY HubSpot migrations go wrong.
These are the things most brands lose when they migrate without a structured process. Each one is fixable, but only if you know to fix it before cutover, not after.
- HubSpot workflows for ecommerce migrated to Klaviyo flows
- List/segment logic rebuilt in Klaviyo using profile properties
- Templates rebuilt (HubSpot designs as reference)
- Form embeds updated to Klaviyo (or kept in HubSpot for B2B-side capture)
- CRM/sales workflows in HubSpot left untouched and continue running

HubSpot to Klaviyo migration FAQ
Q.01 How long does a HubSpot to Klaviyo migration take? +
/ Answer
Three to four weeks. It takes longer than a single-platform move because two systems stay live: ecommerce email moves to Klaviyo while the HubSpot CRM keeps running, and the sync between them has to be tested before cutover.
Q.02 Can I keep HubSpot for CRM/sales after migrating? +
/ Answer
Yes, this is the most common arrangement. HubSpot for sales pipeline + B2B, Klaviyo for ecommerce email + SMS. We bridge the two systems so contact data stays in sync.
Q.03 How does the HubSpot/Klaviyo integration work? +
/ Answer
Klaviyo's help centre states it has no built-in HubSpot integration. The options are a partner-built app from HubSpot's marketplace, a sync tool such as Outfunnel, Zapier or Make, or a custom build on both APIs. We pick based on which data needs to flow which way and your existing tech stack.
Q.04 What does a HubSpot to Klaviyo migration cost? +
/ Answer
It runs as a fixed-scope Project Engagement with a single fee, typically $3-15K depending on scope. Connector subscriptions, if you keep HubSpot as your CRM, are billed by their vendors. The free migration audit puts the exact scope and price in writing within 24 hours.
Q.05 Will moving email to Klaviyo affect my HubSpot reporting? +
/ Answer
HubSpot reporting on email moves with the email, so HubSpot email reports become irrelevant for the migrated channel. Klaviyo reporting takes over. CRM reporting in HubSpot is unaffected.
