Growth Klaviyo Onboarding
Growth takes the solid foundation of Quickstart and builds a complete, strategically structured Klaviyo programme on top of it. Advanced segmentation, SMS automation, a branded email design system, and a deeper automation suite — built to turn new subscribers into loyal, high-LTV customers.
Includes everything in Quickstart — account setup, store integration, welcome series, abandoned cart, post-purchase flow, signup forms, list hygiene, DNS authentication and deliverability foundation.
Most brands that graduate from Quickstart quickly hit the same ceiling: the basics are in place, but the programme doesn't have the depth to drive meaningful retention revenue. Growth is built to close that gap entirely.
Over two to three weeks, we build out a fully-structured Klaviyo programme — layered segmentation, extended automation coverage, an SMS strategy that works alongside your email flows, and a design system that gives every email a polished, on-brand look without requiring a designer every time. The result is a Klaviyo account that runs as a genuine retention engine, not just a sequence of triggered sends.
What's delivered — in addition to Quickstart
- Advanced segmentation framework (RFM-based)
- Browse abandonment flow
- Winback / re-engagement flow
- VIP customer flow
- SMS opt-in flow + 2x SMS automations
- Branded email template design system
- Email list growth strategy & audit
- Reporting setup (Klaviyo dashboards)
- Suppression & sunset flow
- Klaviyo–Shopify / WooCommerce data audit
What's included in detail
Advanced segmentation framework
We build a structured, RFM-based segmentation framework inside Klaviyo that categorises your list by recency, frequency and monetary value. This becomes the backbone of both your campaign targeting and your flow logic — ensuring the right message reaches the right person at the right moment, rather than broadcasting the same content to your entire list.
Extended automation suite
Beyond the core trio delivered in Quickstart, Growth adds the flows that separate high-performing programmes from average ones. A browse abandonment flow captures intent before it slips away. A winback sequence re-engages lapsed customers before they're gone for good. A VIP flow rewards your most valuable customers with content and offers they won't see in your standard sends. A sunset flow removes chronically disengaged contacts before they damage your deliverability.
SMS strategy & automation
SMS, when run through Klaviyo alongside your email programme, is one of the highest-performing retention channels available. We configure your SMS setup, build an opt-in flow that complies with carrier and regulatory requirements, and build two core SMS automations — typically abandoned cart and post-purchase — that complement rather than duplicate your email sequences.
Email design template system
A custom, branded email template designed and built in Klaviyo's drag-and-drop editor — structured to accommodate your most common email types (promotional, product launch, content, transactional) while maintaining visual consistency across every send. Includes a documented component library so your team can produce new emails without starting from scratch.
Email list growth strategy
We audit your current list acquisition touchpoints and produce a practical growth strategy — covering popup optimisation, additional form placements, lead magnet opportunities and any quick-win improvements that will grow your list faster without compromising quality. This is a strategy document with clear, prioritised actions, not a generic checklist.
Reporting & dashboards
Klaviyo reporting configured to surface the numbers that actually matter — flow revenue, campaign performance by segment, list growth rate, deliverability metrics and overall email-attributed revenue. You'll know exactly where your programme is performing and where the biggest opportunities sit.
Typical timeline: 2–3 weeks. A complete, strategically structured Klaviyo programme — from a clean foundation to a fully operational retention engine — delivered in under a month.
How it works
01: Strategy & discovery
We begin with a deeper discovery session than Quickstart — reviewing your existing customer data, purchase patterns and current programme performance to inform the segmentation framework and flow architecture before we build anything.
02: Foundation build (Quickstart deliverables)
Account setup, store integration and core flows are built and launched first, so you're generating revenue while the advanced programme is being developed in parallel.
03: Advanced build
Segmentation framework, extended flows, SMS setup, template system and reporting — all built to a structured plan with clear milestones and regular progress updates.
04: QA, review & handover
Every flow, form and segment is QA'd end-to-end. We walk you through the full programme, explain how each piece works, and hand over with complete documentation.
Who this is for
- Brands that want more than a basic setup — a fully structured retention programme
- Stores doing consistent monthly revenue that need Klaviyo working harder for them
- Teams ready to add SMS alongside email without managing two separate strategies
- Brands that have outgrown their current ESP and want a step-change, not just a migration
- Marketers who want to own a properly documented, well-built Klaviyo account
Frequently asked questions
Do I need to start with Quickstart before upgrading to Growth?
No. Growth includes everything delivered in Quickstart as part of the same engagement. If you're starting fresh or migrating from another platform, we begin at the foundation and build the complete programme without any gap.
Which SMS carriers and markets does this cover?
We support SMS setup for UK, US, EU and Australian markets. Carrier compliance and opt-in requirements vary by region — we configure everything correctly for your specific market and customer base.
What's included in the email template system?
A fully custom, branded email template built in Klaviyo's editor — covering header, footer, promotional, product, and content block layouts. We design it to match your brand identity and build it so your team can use it independently without design support.
Is ongoing support included after delivery?
Growth is a one-time package. Once delivered, the programme is yours to run. Many brands choose to move onto a FlowFixer subscription at this point for continuous optimisation, campaign management and strategic support.

FAQs
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.
