Will we lose subscribers during the migration?

No. We export every profile with full data — email, phone, engagement history, custom properties, tags, and consent status. Everything gets imported into Klaviyo with complete accuracy. We verify counts before and after to confirm zero loss.

Will our deliverability suffer after switching?

Not if the migration is done properly — and that's the whole point of hiring a Gold Partner. We set up domain authentication, create a warm-up schedule, and start by sending to your most engaged subscribers. We gradually increase volume over 2-3 weeks so ISPs recognize your new sending infrastructure as trustworthy.

How long does a full migration take?

Most migrations are complete in 2-3 weeks including warm-up. Complex accounts with 20+ flows and multiple integrations may take 3-4 weeks. We plan every step in advance and give you a clear timeline before we start.

Do you rebuild our existing flows in Klaviyo?

Yes — and we make them better. We don't just replicate what you had. We rebuild every flow using Klaviyo's advanced features: predictive analytics, deeper conditional splits, dynamic content blocks, and better segmentation. Most clients see flow performance improve immediately after migration.

What platforms do you migrate from?

We've handled migrations from Mailchimp, Omnisend, Drip, ActiveCampaign, Constant Contact, HubSpot, and several other platforms. The process is similar regardless of origin — we export everything, rebuild in Klaviyo, and warm up properly.

Klaviyo Migration

Still on Mailchimp? How much revenue are you leaving on the table every month?

Every month you stay on a platform that wasn't built for eCommerce is a month of revenue you can't get back. Mailchimp doesn't have real-time Shopify integration. Omnisend doesn't have Klaviyo's segmentation depth. ActiveCampaign wasn't designed for product catalog feeds and behavioral triggers. You're working twice as hard to get half the results.

Here's what changes when you move to Klaviyo. Real-time Shopify data syncing — every browse, cart, and purchase triggers automations instantly. Predictive analytics that forecast customer lifetime value and churn risk. Segmentation based on actual purchase behavior, not just tags you manually applied. SMS and email in one platform. And the deepest eCommerce integrations in the industry.

But migration is where most brands freeze. Will we lose subscribers? What happens to our existing flows? Will our deliverability tank? Those are valid concerns — and they're exactly why you need a Klaviyo Gold Partner to handle it. We've migrated 50+ brands from Mailchimp, Omnisend, Drip, and ActiveCampaign to Klaviyo. Zero subscriber loss. Deliverability maintained. Flows rebuilt and improved. And we do it in 2-3 weeks so you start benefiting from Klaviyo immediately.

Signs you've outgrown your current email platform

Your email platform doesn't sync real-time purchase data from Shopify — you're segmenting with stale information
You can't build advanced flows with conditional splits based on cart value, purchase count, or product category
SMS is either not available or requires a separate tool that doesn't talk to your email segments
You spend hours manually tagging subscribers because the platform doesn't auto-segment on behavior
Your platform's reporting can't show you revenue per flow or per campaign — just opens and clicks

If more than two of those hit home, you've outgrown your platform. Klaviyo was built for eCommerce from day one — every feature, integration, and data model is designed to help online stores sell more.

What we do for Global brands

Full subscriber migration with zero loss

We export every subscriber, profile property, engagement history, and custom field from your current platform and import it into Klaviyo with full data integrity. Nobody gets left behind.

Flow rebuild and improvement

We don't just copy your old flows — we rebuild them using Klaviyo's advanced features. Better triggers, smarter conditional logic, dynamic content blocks, and proper segmentation. Your flows work better on day one.

Deliverability protection

Domain authentication (DKIM, SPF, DMARC), IP warm-up schedule, engagement-based sending during transition. We protect your sender reputation throughout the migration.

Shopify and platform integration

We connect Klaviyo to your Shopify store, set up catalog feeds, configure tracking snippets, and verify that real-time data is flowing correctly. Everything works the moment we flip the switch.
