Your Client Said Yes to Klaviyo. Now Someone Has to Build the Entire Account from Scratch.
Klaviyo migration specialists for agencies. $25/hr. We build the new Klaviyo account. You handle the old ESP.
The client signed off on moving to Klaviyo. Now your team needs to build every flow from scratch, recreate every segment, design and code every template, configure domain authentication, and warm the sending reputation without tanking deliverability. That's weeks of Klaviyo buildout work on top of the accounts your team is already managing.
SpecialistHQ handles the Klaviyo side of the migration. Your agency exports the data from the old platform. We build the new Klaviyo account: architecture, flows, segments, templates, domain auth, and warming. Your client gets a properly built Klaviyo environment without your senior team disappearing into a migration for a month.

Where Klaviyo Migrations Break Down
The Reality of a Rushed Klaviyo Buildout:
- Your strategist promised the client a 3-week migration. They're now in week five, rebuilding flows between campaign sends for other accounts. Nothing is getting full attention.
- Domain authentication was set up wrong. The first batch of emails from the new Klaviyo account landed in spam. The client is asking what happened.
- The flows were rebuilt but nobody tested the conditional splits with real data. The welcome series is sending VIP offers to first-time visitors.
- Segments were recreated by name but not by logic. Half the segments in the new account don't match what was running in the old ESP.
- The warming plan was "send to everyone on day one." Bounce rates spiked. Gmail throttled the domain. Now you're explaining to the client why their open rates cratered.
What Changes with a Dedicated Migration Team:
- The Klaviyo account is architected properly from the start. Naming conventions, folder structure, segment logic, and flow architecture are documented and consistent.
- Domain authentication is configured correctly the first time. DKIM, SPF, and DMARC records are verified before a single email sends.
- Every flow is rebuilt and tested with real data before it goes live. Conditional splits, time delays, and dynamic content all work as expected.
- Warming follows a structured plan. Engaged subscribers first, small batches, gradual volume increases. Deliverability is protected throughout.
- Your strategist stays focused on their existing accounts. The migration gets done right without pulling anyone off their regular workload.
What We Handle vs. What Your Agency Handles
We are Klaviyo specialists. We build the new Klaviyo account. Your agency or client manages the old ESP. Here's the split.
SpecialistHQ Handles (Klaviyo Side)
New Klaviyo account architecture and configuration. Flow building and testing. Segment creation from imported data. Template design, coding, and QA. Domain authentication setup (DKIM, SPF, DMARC). List import and data mapping (once your team provides the exports). Deliverability warming plan and execution. Shopify-Klaviyo integration setup if applicable. Post-migration QA and parity checks.
Your Agency / Client Handles (Old ESP Side)
Exporting subscriber lists and profile data from the old platform. Pulling historical purchase or event data. Extracting email templates, images, and creative assets. Documenting current flow logic, triggers, and timing. Providing segment definitions and targeting criteria. Managing the teardown or cancellation of the old ESP account. Any work inside the previous platform stays with your team or a partner who specializes in that ESP.
What Your Klaviyo Migration Specialists Build
Klaviyo Account Architecture & Setup
Account configuration from scratch: naming conventions, folder structure, sending domain setup, integration connections, and account-level settings. The foundation that keeps everything organized as the account scales.
Flow Building in New Account
Every flow rebuilt in Klaviyo to match or improve on the old ESP's automation logic. Welcome, abandoned cart, browse abandon, post-purchase, win-back, sunset, and any custom flows. Tested with real data before go-live.
Segment Recreation & List Import
Once your team provides the exported data, we import lists, map profile properties, and recreate every segment. Engagement tiers, purchase behavior groups, geographic segments, and any custom targeting your strategist needs.
Template Design & Build
Email templates designed and coded in Klaviyo's editor or custom HTML. Matched to the client's brand guidelines. Mobile-responsive, tested across email clients, and ready for your team to use in campaigns and flows.
Domain Authentication (DKIM, SPF, DMARC)
Sending domain configuration with proper DKIM, SPF, and DMARC records. We generate the DNS records, guide your team or the client's developer through adding them, and verify everything is authenticated before the first send.
Deliverability Warming Plan & Execution
Structured warming schedule: start with the most engaged subscribers, send in small batches, and gradually increase volume over 2-4 weeks. We monitor bounce rates, spam complaints, and inbox placement at every stage. No mass sends on day one.
How the Migration Works
Scope the Klaviyo Buildout
We review the migration scope together: how many flows, segments, and templates need to be built in Klaviyo. We provide a migration checklist so your team knows exactly what data and assets to export from the old ESP.
Receive Your Exported Data
Your agency exports subscriber lists, profile data, historical events, and creative assets from the old platform. Once we have the data, we begin the Klaviyo buildout. The cleaner the exports, the faster we move.
Build the New Klaviyo Account
We architect the account, import lists, build flows, create segments, design templates, and configure domain authentication. Everything is tested and documented before we hand it to your team for review.
Warm and Verify
Once your agency approves the buildout, we execute the warming plan. Engaged subscribers first, gradual volume increases, deliverability monitoring at every stage. We verify parity with the old ESP's performance before declaring the migration complete.
Why Agencies Trust Us with Klaviyo Migrations
Klaviyo Is All We Build
We don't claim expertise in every ESP. We build in Klaviyo every day. Account architecture, flows, segments, templates, domain auth, and warming — this is our core work. Your migration gets specialists, not generalists.
Clear Scope, No Surprises
We define exactly what we handle (Klaviyo) and what your team handles (old ESP) before work starts. You get a migration checklist, a timeline, and a documented buildout plan. No scope creep, no confusion about who owns what.

Klaviyo Migration Questions
We handle everything inside Klaviyo: account architecture, flow building, segment creation, template design and coding, domain authentication (DKIM, SPF, DMARC), list import (once you provide the data), and deliverability warming. Your agency or client handles the old ESP side: exporting subscriber lists, pulling historical data, extracting email templates or creative assets, and managing the teardown or cancellation of the previous platform. We are Klaviyo specialists — we do not work inside other ESPs.
Most migrations take 2-4 weeks for the Klaviyo buildout, depending on the number of flows, templates, and segments being recreated. Simple accounts with a few flows and basic segments can be done in under two weeks. Complex accounts with 15+ flows, custom templates, and advanced segmentation take closer to four weeks. The warming phase adds another 2-4 weeks after the buildout is complete. We provide a detailed timeline during scoping.
We follow a structured warming plan: start with your most engaged subscribers (recent openers and clickers), send in small batches, and gradually increase volume over 2-4 weeks. We monitor bounce rates, spam complaints, and inbox placement at every stage. If anything looks off, we slow down and adjust. The goal is to build a clean sending reputation on the new Klaviyo domain before you move all traffic over.
We need exported subscriber lists with all profile properties and consent data, any historical purchase or event data you want imported, email templates or screenshots of existing designs, documentation of current flow logic (triggers, splits, timing), and segment definitions. We provide a migration checklist during scoping so your team knows exactly what to export and when. The cleaner the data you provide, the faster we can build.
We handle the Klaviyo side regardless of which ESP your client is leaving. Whether the data comes from Mailchimp, HubSpot, Omnisend, ActiveCampaign, Drip, or any other platform, we build the same thing in Klaviyo: account architecture, flows, segments, templates, domain auth, and warming. We do not log into or work inside the old ESP — that is your agency's responsibility or your client's.
Yes. If the client is on Shopify, we configure the Klaviyo-Shopify integration as part of the migration: connecting the store, verifying event tracking, mapping custom properties, and testing that purchase data, browse events, and product catalog syncs are working correctly.
