The gap most brands are leaving open

Most ecommerce stores leave 25 to 30 percent of revenue unreached by email

Klaviyo is installed. The account exists. But without klaviyo specialists who know what they are doing, the platform captures a fraction of what it should.

Without expert setup

  • Email driving under 10 percent of monthly revenue
  • Sending to the full list with no behavioral segmentation
  • Three default flows that have never been tested or updated
  • Platform data and store data disconnected or out of sync

What expert-led Klaviyo management actually delivers

  • Email contributing 25 to 35 percent of total monthly revenue
  • Behavioral segments that send the right message to the right person
  • Full lifecycle flow coverage with active split testing
  • Clean integration between your store data and email platform

How it works

From kick-off to a fully operating email program in 30 days

Four phases. Clear milestones. Your team invests 3 to 4 hours per week. Our klaviyo specialists handle the rest.

1

Account audit and scope definition

We review your existing account structure, integration health, list hygiene, and flow performance. The audit output defines the exact scope of work with line-by-line deliverables before any contract is signed.

Days 1 to 5 · Your time: 1 hour

2

Architecture and integration build

Deliverability infrastructure, data integration, and segment architecture are built before any email is sent. Getting this layer right is what separates programs that scale from ones that plateau.

Days 6 to 14 · Your time: 2 async reviews

3

Flow and campaign activation

Flows go live in sequence, with QA sign-off at each step. First campaigns are planned and scheduled. The program enters its earning phase within the first calendar month.

Days 15 to 28 · Your time: 1 sprint review

4

Optimization and ongoing management

Monthly reporting, structured testing, and continuous improvement keep performance moving. For ongoing management clients, this phase never ends. For project clients, it transitions to a handover with full documentation.

Proof of results

How our klaviyo experts turned one brand's email into its top revenue driver

An outdoor gear brand, direct-to-consumer, with paid media restrictions. Klaviyo became the primary growth engine.

Outdoor gearDirect-to-consumerKlaviyo on BigCommerce

The challenge

Strict paid advertising restrictions meant the brand could not rely on the channels most ecommerce stores use to scale. They needed owned channels to carry growth. Email was installed but contributing under 12 percent of monthly revenue with no behavioral automation in place.

The solution

Our klaviyo marketing agency rebuilt the full program: advanced behavioral segmentation, a complete lifecycle flow architecture, a structured campaign calendar with split testing, and monthly attribution reporting. Klaviyo became the primary revenue engine within 90 days of the program going live.

Why this klaviyo agency is different

Specificity is what most klaviyo agencies do not offer

Broad agencies promise outcomes. We commit to a specific scope, a specific price, and a specific timeline before you sign anything.

Scoped before work starts

Every engagement begins with a full account audit. The scoped proposal lists every deliverable, every milestone, and the complete cost before you commit. No vague retainers, no scope creep.

Attribution-first reporting

Every report shows exactly which flows, campaigns, and segments are driving revenue. You never need to ask whether the program is working. The attribution is tracked from day one and reported monthly.

You own everything built

All flows, templates, segments, and code built in your Klaviyo account belong to you from day one. No proprietary lock-in. If you switch teams or bring management in-house, everything is documented and transferable.

Platform integration depth

We work with Klaviyo across BigCommerce, Shopify, and custom stacks. Integration setup, data sync, and custom event tracking are included in scope, not added as a later discovery. See our full Klaviyo email marketing services.

Senior specialists on every account

No account managers passing work to juniors. Your lead klaviyo specialist handles strategy, build, and optimization throughout the engagement. Direct access included. No escalation queue.

Adjacent services when you need them

Email rarely exists alone. Our team also covers Klaviyo consulting for strategy audits and Klaviyo managed services for full account ownership, so you are not patching gaps with a second vendor.

Common questions

Questions about hiring klaviyo specialists

Everything you need before deciding whether this is the right fit for your email program.

Klaviyo experts bring cross-account pattern recognition that an in-house team builds slowly. They have seen what works across dozens of ecommerce verticals and know which flow architectures, segment rules, and send strategies move revenue in the first 30 days, not month six. They also know the platform edge cases, the deliverability pitfalls, and the attribution quirks that turn a promising program into a consistent revenue channel.

Most brands see measurable lift from automated flows within the first 30 days of a properly structured program, because flows run continuously on autopilot. Campaign revenue builds over 60 to 90 days as segmentation matures and send cadence stabilises. Full program performance, where email is consistently driving 25 to 35 percent of monthly revenue, typically takes 90 to 120 days.

We offer both. The Foundation and Full Program tiers are project-based engagements that end with a fully built program handed to your team with documentation and a recorded walkthrough. Ongoing Management is a monthly retainer where we run the full account: campaigns, flows, segmentation, and reporting, alongside a monthly strategy call to review results and plan the next send calendar.

Pricing varies by scope. A foundation setup covering core flows and initial segmentation typically starts in the low thousands. A full program buildout covering lifecycle flows, campaigns, and deliverability infrastructure is scoped individually based on list size, platform complexity, and integration requirements. Ongoing management retainers are scoped before work starts so you know the exact line-item breakdown before committing. See our full Klaviyo management pricing for reference ranges.

The cost of waiting is measurable: every month without a properly segmented, automated Klaviyo program is revenue left on the table. If your store is doing at least 30,000 dollars a month and you have a list of 5,000 or more subscribers, the program pays for itself in most cases within the first 60 to 90 days. Waiting until you grow larger means growing more slowly, because email is one of the highest-return owned channels available to ecommerce brands.

Is this the right fit?

Who this works best for

Before you submit a brief, here is a straight answer on when to hire Klaviyo experts and when another approach makes more sense.

Good fit for your brand if

  • Email currently contributes below 20 percent of total monthly revenue
  • You have at least 12 months of transaction data and a list of 5,000 or more subscribers
  • You are sending campaigns inconsistently or relying on one or two basic automated flows
  • No full-time Klaviyo specialist on the team and email has become too important to manage part-time
  • Monthly store revenue of 30,000 dollars or more and growing

Not a fit if

  • You need a one-time setup only and want no ongoing management involvement from us
  • Monthly store revenue is below 30,000 dollars and the list is under 1,000 subscribers
  • You are selling a single low-ticket product to a cold audience with no repeat purchase potential
  • You want in-house training only with no managed work performed by an outside team

Not sure which fits you? Tell us your situation and we will give you a straight answer.
