Get help with setting up Klaviyo for your ecommerce brand, with our bespoke Klaviyo setup and onboarding service, designed to get your lifecycle marketing going
Klaviyo Setup is designed for ecommerce brands looking to implement the platform correctly from day one. Many businesses install Klaviyo but fail to configure it in a way that supports long-term lifecycle growth. FlowFixer ensures that every part of the setup is aligned with revenue generation, data accuracy and scalability.
The process begins with a full audit of your ecommerce platform, data sources and customer journey. FlowFixer then configures Klaviyo to ensure clean data flow, accurate event tracking and a structure that supports advanced segmentation and automation. This includes integrating platforms such as Shopify or WooCommerce and ensuring all key customer events are captured correctly.
Beyond technical setup, FlowFixer also establishes the strategic foundation for lifecycle marketing. This includes defining key customer segments, identifying lifecycle stages and mapping out initial automation opportunities. The goal is to ensure Klaviyo is not just installed, but fully prepared to drive retention revenue.
A properly configured Klaviyo account enables accurate reporting, better targeting and more effective automation. It also prevents common issues such as poor deliverability, incorrect segmentation and unreliable data.
By setting up Klaviyo correctly from the start, brands can avoid costly rework later and ensure their lifecycle marketing efforts are built on a strong and scalable foundation.
FlowFixer focuses entirely on lifecycle marketing, with every strategy and automation designed to increase revenue from existing customers. By specialising in retention rather than multiple marketing channels, the team helps brands turn repeat purchases and customer engagement into a consistent source of growth.
FlowFixer is built around deep expertise in Klaviyo. Instead of treating email marketing as a secondary service, the team focuses on unlocking the full power of the platform through advanced automation, segmentation and personalisation.
As ecommerce brands grow, their lifecycle marketing becomes more complex. FlowFixer builds structured automation systems that scale with the business, allowing new products, segments and customer behaviours to be added without creating operational complexity.
Every lifecycle decision is guided by customer data. By analysing behaviour, purchases and engagement patterns, FlowFixer identifies the opportunities most likely to increase retention and repeat purchases.
Lifecycle marketing requires constant improvement. FlowFixer continuously tests flows, messaging and campaigns to improve performance, helping brands steadily increase conversions and revenue from their lifecycle channels.
FlowFixer helps brands deliver timely and relevant messaging throughout the customer journey. This strengthens trust, builds loyalty and encourages customers to come back again and again.
Wondering how we help ecommerce marketers streamline their Klaviyo workflows to achieve outstanding results? Check out our FAQs.
What is FlowFixer?
FlowFixer is a Klaviyo agency specialising in ecommerce email and SMS retention marketing. We help brands increase repeat purchase rate and customer lifetime value by designing, building, and optimising high-impact lifecycle flows in Klaviyo.
Is FlowFixer an email marketing agency or a Klaviyo specialist?
FlowFixer is a Klaviyo-only ecommerce email marketing agency. We don’t work across multiple platforms. That focus allows us to deliver deeper strategy, faster execution, and better results than generalist email agencies.
What does FlowFixer do?
FlowFixer designs, builds, and optimises Klaviyo email and SMS flows that drive measurable retention revenue. We focus on lifecycle strategy, high-impact flows, segmentation, and continuous optimisation, not one-off campaigns or generic templates.
Who is FlowFixer for?
FlowFixer is built for ecommerce brands using Klaviyo on Shopify or WooCommerce that want to grow retention revenue without hiring a full in-house lifecycle team.
Do you only work with Klaviyo?
Yes. FlowFixer is Klaviyo-specialist by design. That focus allows us to move faster, go deeper, and deliver better results than generalist email agencies.
What does FlowFixer actually work on?
We focus on:
- Ecommerce email marketing strategy
- Klaviyo flow setup and optimisation
- Email & SMS lifecycle automation
- Segmentation and personalisation
- Retention marketing performance tracking
Everything we do is prioritised around revenue impact and customer lifetime value.
How is FlowFixer different from other Klaviyo agencies?
Most Klaviyo agencies focus on volume: more flows, more campaigns, more activity.
FlowFixer focuses on incremental revenue, identifying the small number of lifecycle improvements that drive the biggest lift in retention, conversion rate, and LTV.
Do you help improve customer lifetime value (LTV)?
Yes. Increasing customer lifetime value is a core goal of FlowFixer. We optimise flows, timing, segmentation, and messaging to turn first-time buyers into repeat, high-value customers.
What’s included in the subscription?
Your subscription covers lifecycle strategy, flow creation and optimisation, segmentation, personalisation, deliverability best practices, reporting, and ongoing improvements, all prioritised around revenue impact.
Is this strategy only, or do you execute as well?
Both. FlowFixer handles the thinking and the doing. We don’t hand over a strategy deck and walk away, we implement, test, and iterate.
How is FlowFixer different from a traditional email agency?
Most agencies focus on volume and outputs. FlowFixer focuses on outcomes. We prioritise the flows and changes that generate the most incremental revenue, rather than shipping work for the sake of it.
How quickly can we get started?
Onboarding is fast. Once you’re live, we audit your account, identify quick wins, and begin working on high-impact flows immediately.
How do you measure success?
We measure success using:
- Retention revenue
- Flow-driven conversion rate
- Repeat purchase rate
- Customer lifetime value
Open rates and click rates are secondary indicators, not the end goal.
Can FlowFixer work alongside our internal team or paid media agency?
Yes. FlowFixer often complements in-house teams, paid media agencies, and CRO partners by owning the retention and lifecycle marketing layer.
Is there a minimum commitment?
FlowFixer runs on a simple monthly subscription with no long-term lock-in. Our clients stay because it works, not because they’re tied to a contract.
