Klaviyo agency · Europe and international

A Klaviyo agency built for ecommerce operators

Klaviyo is useful when profiles, events, segments, campaigns and flows work as one system. Most underperforming accounts do not need another isolated automation. They need a reliable data model, a clear lifecycle plan and an operating rhythm the team can maintain.

Deliver helps ecommerce brands turn that system into a measurable revenue channel. We audit the setup, fix the foundations, build the priority journeys and establish the reporting needed to make better decisions after launch.

What we work on in Klaviyo

Data and tracking

Every flow depends on the event that starts it and the fields used by its filters. We review profile identity, consent, catalogue data and the events sent by Shopify or your custom stack. We also check whether refunds, cancellations and subscription events are available when your lifecycle logic needs them.

If you are starting from scratch, use our Klaviyo Shopify setup guide to see the controls we expect before an account goes live.

Lifecycle flows

We map each journey to a customer signal instead of filling the account with overlapping sequences. Typical priorities include welcome, browse abandonment, cart and checkout abandonment, post-purchase, replenishment, winback and sunset flows.

Filters and exclusions matter as much as the emails themselves. Our guide to Klaviyo abandonment flows explains why browse, cart and checkout intent should not trigger the same treatment.

Campaigns and segmentation

Campaign performance improves when the audience, offer and send pressure are planned together. We define practical segments for new subscribers, recent buyers, repeat customers, high-value customers, at-risk customers and disengaged profiles. The goal is not to create hundreds of segments. It is to give each recurring campaign a clear audience rule.

Deliverability

We review authentication, list acquisition, complaint and bounce signals, engagement policies and send-volume changes. Moving to Klaviyo does not repair a damaged sender reputation on its own. The account needs explicit rules for who receives marketing, when an inactive profile enters a re-engagement journey and when sending stops.

Reporting and experimentation

Klaviyo attribution is one view of performance, not the whole commercial truth. We separate platform reporting from business outcomes, define a small KPI set and document how tests will be evaluated. That prevents a higher attributed-revenue number from being mistaken for incremental growth.

How an engagement starts

1. Diagnostic

We examine the account, integrations, events, consent, templates, active flows, campaign process and reporting. The output is a prioritized action plan with dependencies, owners and expected measurement.

2. Foundation fixes

We correct tracking, naming, suppression logic and deliverability issues that would make new journeys unreliable. When a required event is missing, we resolve that before building the flow that depends on it.

3. Build and quality assurance

We write, design, configure and test the agreed flows or campaigns. Tests cover entry rules, filters, message rendering, dynamic content, links, consent and exit conditions.

4. Launch and operating rhythm

After launch, we monitor delivery and customer behavior, then establish the campaign calendar, test backlog and reporting cadence. Your account should become easier to run, not more dependent on hidden agency knowledge.

When Deliver is a good fit

We are usually a strong fit when:

If you are still deciding whether the platform belongs in your stack, read Is Klaviyo a CRM?. It explains what Klaviyo can replace and where a sales or service CRM may still be necessary.

What you keep after the engagement

The work is documented around events, audiences, flow logic, campaign rules, measurement and ownership. Your team keeps the account structure, decision framework and test backlog. We can continue operating the program or hand it over with training and clear maintenance rules.

FAQ

Can you take over an existing Klaviyo account?

Yes. Most engagements begin with an existing account. We audit what should be kept, fixed, consolidated or retired before adding new work.

Do you only work with Shopify?

No. Shopify is common, but we also work with other ecommerce and custom stacks. The key question is whether the required identity, catalogue, order and consent data can be sent reliably.

Can you migrate us from another email platform?

Yes. A migration plan can cover data mapping, consent, forms, templates, active automations, suppression lists, tracking and a staged launch. We do not switch systems until the continuity risks are mapped.

Do you manage campaigns as well as flows?

Yes. We can build the lifecycle foundation, operate recurring campaigns or combine both. Scope depends on your internal team and the production rhythm required.

How do we start?

Book a diagnostic call. We will review the current setup, identify the main constraint and decide whether an audit, a build project or ongoing support is the right next step.
