Klaviyo email marketing agency
Get the most out of Klaviyo – with a team that’s run it since 2016
Klaviyo is only as powerful as the strategy behind it. We build, migrate, and manage Klaviyo accounts for ecommerce brands, turning flows, segments, and data into a revenue channel that runs 24/7.
Why Klaviyo
It’s a customer data platform, not just email.
Klaviyo syncs real-time behavioral data directly from your Shopify store-from browsing patterns to predicted lifetime value-allowing you to send hyper-personalized messages when intent is highest.
How we unlock its full revenue potential:
- Turn Data into Revenue: We map raw customer behaviors into high-converting lifecycle journeys.
- Scale Beyond Broadcasts: Transform standard email blasts into predictable, automated sales engines.
- Maximize ROI: Stop leaving money on the table by utilizing advanced logic, predictive analytics, and dynamic segmentation.
Our Klaviyo services
Frameworks That Scale with Your Store
Flows & automation
We build and optimize the full lifecycle in Klaviyo: welcome, abandoned cart, browse abandonment, post-purchase, win-back, replenishment, using Klaviyo’s conditional splits, triggers, and A/B testing to squeeze revenue from every path.
Campaigns & calendar
Segmented campaigns planned, designed, and sent in Klaviyo, with performance tracked against your benchmarks.
Deliverability & account health
Domain authentication (SPF, DKIM, DMARC), sending-reputation management, and list hygiene, the technical foundation that keeps you in the inbox.
Klaviyo SMS
Native SMS built inside Klaviyo, so email and SMS share one profile, one segment, and one coherent journey.
Migration to Klaviyo
Moving from Mailchimp, Omnisend, or another platform? We handle the full migration: data, flows, templates, and authentication, with no gap in sending.

Many ecommerce brands hesitate to optimize or migrate their email setup because they’ve heard the horror stories – damaged domain reputation, broken flows, high unsubscribe rates, or wasted ad spend. Those risks exist when strategy and technical setup are handled incorrectly.
Here’s what a professional Klaviyo management eliminates:
- No spam folder landings – domain authentication (SPF, DKIM, DMARC) and deliverability hygiene guarantee inbox placement
- No broken automations or lost revenue – bulletproof flow logic and triggers capture every abandoned cart and browser lead
- No list fatigue or high unsubscribes – smart behavioral segmentation ensures customers receive only targeted, relevant messages
- No wasted data or lost customer history – flawless migration and integration retain all your historical segments and metrics
A well-planned retention strategy replaces uncertainty with peace of mind. You keep your sender reputation, maximize subscriber value, and turn your email list into a predictable, high-ROI revenue channel.

This page is about our Klaviyo work specifically, but no, we’re also certified on theMarketer, Omnisend, and Brevo. If you’re on another platform, we’ll tell you honestly whether moving to Klaviyo is worth it for your business. For a platform-agnostic approach, explore our email and retention marketing services.
2. Can you migrate us to Klaviyo without losing data or sending history?
Yes. We handle the full migration, profiles, consent status, flows, templates, and domain authentication, with no gap in sending.

Rebuilt flows can start recovering revenue within the first weeks. Overall email revenue share typically climbs over the first few months as we test and refine.
Can you manage my flows long-term? Yes. We handle ongoing optimization, testing, and performance monitoring, not just the initial build.
