Getting the Most Out of Klaviyo

When an ecommerce brand reaches a certain level of maturity, the problem is no longer “sending more emails.” The real challenge is turning Klaviyo into a reliable, measurable retention system that’s easy to scale.

Klaviyo is a powerful platform. Yet in practice, its potential often remains only partially leveraged because teams are caught between two competing needs: structuring what they do to avoid creating debt, while continuously delivering (campaigns, new products, promotions, content). The challenges fall into three critical dimensions:

Deliverability is eroding due to send pressure
List hygiene is not systematized
Flows are stacking up and creating inconsistencies
Consents and preferences are poorly structured
Measurement isn’t organized for fast decision-making

The objective is simple: enable your ecommerce and marketing teams to extract more value from Klaviyo, without multiplying tools or weighing down operations.

This requires a clear Klaviyo foundation, actionable data, advanced flows, and a method that makes strategy and execution smoother day-to-day. The result: stronger retention, a better customer experience, and a system that keeps performing as complexity grows.

The problem in an advanced Klaviyo context

On Klaviyo, the challenge is no longer having flows. The challenge is maintaining a system that stays performant, coherent, and measurable as the list grows, journeys multiply, and new channels are added (SMS, push).

Klaviyo can keep generating revenue while becoming increasingly difficult to optimize without creating risks. The challenges fall into three critical dimensions.

Poorly calibrated send pressure weakens reputation and effectiveness:

  • Excessive send pressure on low-engagement segments erodes sender reputation. When reputation drops, everything becomes harder—even important messages.
  • List hygiene is not systematized: inactive contacts remain “watered” too long, pressure reduction rules are unclear, and performance becomes unstable.
  • Spam complaints, unsubscribes, or bounces increase but are not treated as structural signals with defined decision thresholds.

Klaviyo architecture grows more complex over time:

  • Flows stack up, overlap, and create inconsistencies (priorities, exclusions, timing), weakening the customer experience.
  • Duplications appear to handle specific cases, instead of a modular structure that’s simpler to maintain.
  • Flows are not analyzed as systems: trigger, delays, conditions, exclusions, objective, and impact on the rest of the ecosystem.

Compliance and measurement become critical challenges:

  • Consents and preferences poorly structured, especially when SMS is added, increasing operational risk and limiting orchestration.
  • Canada-specific constraints (CASL) and explicit opt-in requirements for SMS, demanding rigorous management.
  • Performance reading difficult to steer: which flows deserve iteration, which segments create value, which campaigns cannibalize engagement.

Signs it’s time to optimize Klaviyo differently

If you recognize yourself in these situations, your Klaviyo environment has likely reached a point where performance depends primarily on structure and discipline:

1
Deliverability is becoming unstable: rising bounces, more sends landing in spam
2
The list is growing but engagement is declining, and inactive contact hygiene is not rigorously managed
3
Unsubscribes or complaints are increasing: you need to reduce pressure without knowing what to fix first
4
Automations are overlapping: you’re losing control over who receives what, and when
By industry

Klaviyo optimization adapted to your reality

We work with brands whose operational, marketing, and organizational realities are very different. Priorities vary by sector, volume, business model, and team maturity.

Performance relies on recurrence, loyalty, and personalization. Klaviyo must support relational journeys (post-purchase, replenishment, VIP, winback) that increase customer value without unnecessarily increasing send pressure. The challenge is to iterate continuously with smooth execution.

Methodology

The Lake House Group approach

Lake House Group helps teams extract more value from Klaviyo without multiplying projects or destabilizing what already works, following three structured steps.

01

Foundation

We consolidate the foundations so Klaviyo becomes a true retention lever:

  • Diagnosis of friction points and opportunities (deliverability, flows, segmentation, compliance, measurement)
  • Data structuring (profiles, events, products, properties useful for personalization)
  • Architecture clarification (naming, logic, exclusions, frequency, governance)
  • Solid foundations to automate, test, and evolve without debt
02

Automation

We activate the flows and campaigns that generate the most value:

  • Refactor and optimization of critical workflows (cart, browse, post-purchase, winback, VIP, replenishment, back-in-stock)
  • Modular and scalable flows, designed to be iterated without breaking everything
  • Reduction of manual operations and case-by-case adjustments
  • Smoother production and deployment: copy, design, integration, QA, and iteration cadence
03

Evolution

We continuously improve retention performance:

  • Data-driven continuous improvement (tests, learnings, priorities)
  • Clear governance and team capacity building
  • Progressive activation of additional channels (SMS, push) only when they deliver real gains
  • Long-term partnership: stability, performance, and a system that improves month after month
