Klaviyo agency · Paris

A Klaviyo agency for ecommerce teams in Paris

Deliver supports Paris-based ecommerce teams remotely. We do not claim a local office that does not exist. Work is delivered through video, asynchronous project management, and documented decisions, with an in-person workshop only when it is explicitly included in the engagement.

We audit, implement, migrate, and operate Klaviyo across data, lifecycle flows, campaigns, segmentation, deliverability, quality assurance, and reporting.

What we can own in Klaviyo

Account audit and roadmap

We review:

The output separates customer and compliance risk, technical defects, lifecycle opportunities, and dependencies. We do not recommend a flow before confirming that the required event and properties are reliable.

Our 50-point lifecycle audit scorecard shows the breadth of the review.

Klaviyo setup or repair

For a new or incomplete account, we define:

The Klaviyo Shopify setup guide details the controls we expect before customer journeys go live.

Migration to Klaviyo

A migration is more than a CSV upload. We map:

Flows are rebuilt and tested before the old sender is retired. Every message has one owner during the transition to prevent duplicate customer communication.

Lifecycle flows

Depending on the business, priorities may include:

Each flow has a customer job, trigger, eligibility, exclusions, timing, exits, QA plan, measurement, and owner. We keep the architecture simple enough to operate.

Campaigns and SMS

We can manage:

A campaign needs a real reason to send: product education, launch, proof, replenishment, loyalty, seasonal relevance, or an honest promotion. SMS is used only where immediacy adds value and channel-specific consent exists.

Deliverability

We review authentication, acquisition sources, bounce and complaint signals, volume changes, inactive profiles, and available mailbox-provider evidence.

No agency can guarantee inbox placement because mailbox providers and recipients control the outcome. We establish the technical and operating controls that reduce risk and make problems diagnosable.

When Deliver is a good fit

We are usually a strong fit when:

We can also support SaaS or service businesses when the scope is lifecycle, product events, onboarding, activation, or retention. We do not replace a sales CRM or sales operations team.

Remote delivery, without false local claims

For Paris teams:

This model lets the buyer evaluate team, method, data competence, output, commercial terms, and handover instead of selecting an agency from an address.

Our guide to choosing a Klaviyo agency provides eight evaluation criteria.

How the engagement works

1. Scope

We clarify the business model, markets, stack, channels, constraints, and responsibilities. Access is individual and limited to the work.

2. Diagnostic

We inspect data and the account. The roadmap ranks findings by risk, impact, confidence, effort, and dependency.

3. Specification

Every priority flow or campaign receives:

4. Production

Copy, design, configuration, and technical setup follow the same specification. Links, coupons, dynamic data, mobile, language, exclusions, and pressure are tested.

5. Controlled launch

We use representative test profiles and a limited rollout when risk justifies it. A named owner can pause the journey.

6. Operation and learning

Reviews connect evidence to a decision: keep, repair, stop, or test. Material rules and changes remain documented.

Engagement formats

Klaviyo audit

For a team that keeps execution internally but needs independent diagnosis and priorities.

Setup or migration project

For data mapping, integrations, forms, templates, flows, QA, and controlled cutover.

Monthly lifecycle operation

For campaigns, flow maintenance, deliverability monitoring, analysis, and the next roadmap with the internal team.

Specialist workstream

For a defined need such as migration, data, deliverability, lifecycle flows, experimentation, or a seasonal campaign program.

Pricing depends on markets, data complexity, production volume, and the responsibility split. We do not publish a universal package that hides those differences.

How we measure

The metric set can include:

Klaviyo-attributed revenue is useful for program operation, but it does not prove that the message caused the order. We use holdouts or controlled rollout for material flows when volume supports it.

FAQ

Does Deliver have a Paris office?

No. The team works remotely. An in-person workshop can be included, but this page does not claim a local office.

Can you take over an existing Klaviyo account?

Yes. We determine what should be kept, repaired, consolidated, or removed before adding new flows.

Do you work only with Shopify?

No. Shopify is common, but WooCommerce and custom stacks can work when identity, catalog, orders, consent, and events are reliable.

Do you manage both campaigns and flows?

Yes. The engagement can cover both or one workstream depending on the internal team. Responsibilities and approval points are agreed before production.

Do you guarantee a revenue percentage?

No. Results depend on product, repeat behavior, acquisition, audience, margin, promotion, and attribution. We set targets after reviewing the baseline.

Who owns the account and deliverables?

The brand keeps its account, domains, audiences, templates, and customer data. Important rules are documented for handover.
