The limits your Omnisend account is starting to show
Flat automation library: Omnisend flows have limited branching logic. Browse abandonment, predictive win-back, and cross-sell sequences are either absent or require workarounds that break on platform updates.
Limited segmentation depth: Property-based segments only. No behavioral scoring, predictive lifetime value ranking, or purchase-pattern logic that Klaviyo builds natively.
Shared sending infrastructure: Your deliverability is tied to the behavior of everyone else on the same Omnisend sending pool. One bad actor in the pool affects your inbox placement.
Non-portable engagement history: Your contact engagement data does not transfer cleanly when you move from Omnisend to Klaviyo. Without a structured export and re-mapping process, you start Klaviyo with a cold list.
What the right omnisend to klaviyo migration actually solves
A properly scoped omnisend klaviyo migration agency handles more than a list export. You leave with a clean Klaviyo account, full automation coverage, a dedicated sending domain, and tested deliverability before the first live campaign.

Contact Data Snapshot
Suppressed and invalid contacts are not isolated. They will trigger flows, inflate segment counts, and increase your spam complaint rate if imported without hygiene.
After: Your Klaviyo account
Contact Data Snapshot
Clean list hygiene from day one. Suppressed contacts are managed separately. Predictive lifetime value and engagement scores are available on every active profile.
Every deliverable your move from Omnisend to Klaviyo requires
A complete scope with no line items omitted. You receive a fully operational Klaviyo account, not a data dump with a launch-it-yourself handover.
Contact migration and list hygiene
Your full contact database is exported from Omnisend, cleaned for invalid and suppressed records, and imported into Klaviyo with all custom properties mapped and preserved. No contacts are lost, and no invalid addresses enter your active segments.
Full automation rebuild
Every active Omnisend flow is rebuilt from scratch inside Klaviyo using native triggers, behavioral conditions, and properly structured time delays. We add the flows you were missing, including browse abandonment, cross-sell, and a multi-stage win-back sequence.
Deliverability infrastructure setup
A dedicated sending domain is configured and authenticated with SPF, DKIM, and a DMARC quarantine policy. A 14-day warmup schedule runs before your first live campaign. You leave Omnisend's shared sending pool behind on day one.
Behavioral segment architecture
Your Klaviyo account is built with 14 behavioral segments from launch, covering lifetime value tiers, purchase frequency, browse and cart engagement, win-back windows, and sunset criteria. These are not properties list exports.
Quality assurance on every flow
Every flow is tested against real contact scenarios before launch. Trigger conditions, split logic, timing delays, and unsubscribe handling are verified. You sign off on a quality assurance report before any flow goes live.
30-day post-launch monitoring
After launch, we monitor your deliverability metrics, open rates, and spam complaint rate for 30 days. Any warmup anomalies or performance dips are addressed before they affect your sender reputation. Handover includes a performance summary and ongoing recommendations.

Submit brief → call within 48 hours → scoped proposal in 3 days → Sprint 1 within 1 week of sign-off
Your team typically invests 3 to 4 hours across the entire project: one account review call, async approvals on rebuilt flows, and a final sign-off before go-live.
Your omnisend to klaviyo migration in four stages
Each stage has a fixed scope, a clear owner, and a defined handover moment. Nothing is vague or open-ended.
Account review and export brief
We audit your full Omnisend account: all lists, automations, custom properties, and sending history. You receive a migration scope document with every item that needs to be rebuilt and every decision to be made.
Duration: 3 to 5 business days
Contact migration and list hygiene
Your Omnisend contact database is exported, cleaned of invalid and suppressed records, and imported into Klaviyo with all custom properties mapped. The deduplicated sending domain is authenticated and the warmup schedule begins.
Duration: 2 to 3 business days
Automation rebuild inside Klaviyo
Every active Omnisend flow is rebuilt in Klaviyo with native triggers, branching logic, and proper time delays. Additional flows not present in your Omnisend account are built to complete your lifecycle coverage. You review each rebuild before it moves to quality assurance.
Duration: 5 to 8 business days
Quality assurance and go-live
Every flow is tested against real trigger scenarios. The quality assurance report is shared and reviewed with your team. After sign-off, flows are activated in sequence, deliverability metrics are monitored, and the 30-day post-launch window begins.
Duration: 2 to 3 business days

How Gameday Gear made email generate 29.3% of all conversions
A headless ecommerce brand with no reliable email integration turned Klaviyo into its most measurable, highest-converting revenue channel through a complete implementation.
Gameday Gear operates an enterprise ecommerce platform on a headless architecture. With no reliable way to pass customer behavior into Klaviyo, email marketing was inconsistent, tracking was unreliable, and automation performance was unmeasurable.
Customer behavior, product catalog data, and conversion events were not reaching Klaviyo in a structured way. Tracking was browser-only and dropped frequently. Lifecycle campaigns could not trigger on real user actions, and list data was stale.
A complete Klaviyo implementation was delivered end to end. Custom backend APIs connected the headless ecommerce platform directly to Klaviyo using server-side tracking. Customer profiles, product catalog data, and all conversion events were synchronized through Klaviyo REST APIs. Lifecycle flows, event naming conventions, and list hygiene were rebuilt from the ground up.

Full migration covers exporting all contacts with custom properties from Omnisend, rebuilding your automation library inside Klaviyo with real triggers and conditions, recreating segments with behavioral logic, authenticating your sending domain, and running quality assurance on every flow before handover. You receive a complete Klaviyo account that is tested, live, and ready to generate revenue.
Most migrations are complete and live within 14 to 21 business days depending on the complexity of your current Omnisend automation library. The timeline covers discovery, a clean contact export with list hygiene, flow rebuild inside Klaviyo, domain authentication, and quality assurance. You will have a scoped timeline in your proposal before any work begins.
Yes. Klaviyo supports both email and SMS marketing. During the migration, we map your Omnisend SMS subscribers and consent data into Klaviyo profiles so your text marketing flows can be rebuilt and tested alongside your email automations. No subscriber data is discarded. The short message service opt-in consent you collected in Omnisend is documented and preserved in the Klaviyo profile record.
Every active flow in Omnisend is rebuilt from scratch inside Klaviyo using native triggers, conditions, and time delays. We do not import generic copies. Each automation is configured to match the intent of the original flow and then tested against real contact behavior before it goes live. You review each rebuilt flow before the quality assurance sign-off.
In-house migrations typically result in flat list imports, simplified automation rebuilds, and skipped domain authentication steps, which leads to deliverability problems after launch. Our team handles the full technical scope, including contact hygiene, behavioral segment logic, custom property mapping, and deliverability monitoring for the first 30 days after go-live. You receive a migration that is complete, not just started.
Who this migration is built for
Good fit for
Brands with 2,000 or more subscribers in Omnisend sending at least 2 campaigns per month
Teams whose Omnisend plan costs are growing faster than email revenue
Marketers who want advanced behavioral segmentation that Omnisend's automation builder cannot support
Stores on Shopify or BigCommerce that want Klaviyo's native commerce integration rather than a third-party connector
Brands seeing spam complaint rates above 0.08% who need a fresh deliverability foundation
Not a fit if
You are on Omnisend's free plan with under 500 subscribers where migration cost exceeds the value gained
You need the migration completed in under 5 business days as quality assurance requires a minimum of 14 days
You want a data export only with no flow rebuilds or quality assurance as we do not offer data-dump migrations
Your platform requires a custom API integration with Klaviyo as a prerequisite before migration can begin
