Ultimate

The Ultimate is for brands that want everything — a full 10-flow lifecycle automation programme, a loyalty setup that drives genuine repeat purchasing, and three months of dedicated support so the programme doesn't just launch well, it performs consistently over time.

Includes everything in The Accelerator — which includes everything in The Launchpad. Branded template, five automation flows, segmentation framework, list growth strategy, reporting setup and a 30-day check-in.

Most eCRM packages, including the good ones, stop at delivery. The flows are built, handed over, and what happens next is left to the brand. For brands scaling quickly, running complex programmes or managing multiple product categories, that handover moment is exactly where value starts to erode. Flows don't get optimised. Loyalty programmes don't get extended. The reporting numbers get read but not acted on.

The Ultimate is structured differently. The build is the beginning — what follows is three months of dedicated FlowFixer support, where we work alongside your team to monitor performance, run A/B tests, extend the programme as your data matures, and make the kind of continuous improvements that turn a well-built eCRM programme into a genuinely high-performing revenue channel.

What's delivered — in addition to The Accelerator

  • 10× automation flows (full lifecycle coverage)
  • Back-in-stock & price drop flows
  • Cross-sell & upsell flow sequences
  • Loyalty programme setup & integration
  • Loyalty milestone & reward flows
  • Advanced A/B testing setup
  • Predictive CLV segmentation
  • 3× months dedicated support (monthly planning + async)
  • Quarterly strategy review & roadmap
  • Priority access to FlowFixer delivery team

What's included in detail

Complete 10-flow automation programme

The full lifecycle automation suite — covering every commercially significant moment in your customer journey. In addition to the five flows delivered in The Accelerator, The Ultimate adds back-in-stock notification flows (critical for inventory-constrained brands), price drop alerts for subscribers who viewed a product without purchasing, cross-sell and upsell sequences built around purchase history and product affinity data, and a replenishment flow for brands with consumable or repeat-purchase product categories. Every flow is built with advanced conditional logic that adapts content based on customer behaviour, purchase history and segment membership.

Loyalty programme setup & integration

A loyalty programme, properly integrated with Klaviyo, is one of the most effective retention tools available to ecommerce brands. We set up your loyalty platform — working with LoyaltyLion, Yotpo Loyalty, Smile.io or your existing setup — and build the automation flows that make it genuinely earn its place in your programme. Points milestone emails that celebrate progress. Tier upgrade notifications that reinforce the value of loyalty status. Reward redemption nudges with clear urgency. Expiry reminders that drive purchasing before value is lost. These aren't decorative additions to a loyalty programme — they're what makes one actually work.

Advanced A/B testing framework

A structured testing programme across your most impactful flows — with a documented test calendar, a clear methodology for reading results at statistical significance, and a framework for implementing winners without disrupting live programmes. Subject lines, send timing, offer type, email length, CTA treatment and dynamic content variations — all tested in a way that compounds improvements over the three-month support period.

Predictive CLV segmentation

Klaviyo's predicted customer lifetime value and churn risk models are configured and embedded into your segmentation framework and flow logic — so your programme is acting on where customers are going, not just where they've been. High-CLV prospects receive elevated nurture sequences. Churn-risk customers trigger intervention flows before they lapse. Low-LTV segments are managed to protect deliverability rather than being sent the same content as your best customers.

Three months of dedicated support

After the programme launches, a dedicated FlowFixer strategist works alongside your team for three months. Monthly planning sessions to review performance data, identify optimisation opportunities and prioritise what to work on next. Async support for questions, adjustments and guidance between sessions. Active A/B test monitoring and winner implementation. Flow performance reviews and recommendations. This isn't account management — it's a specialist working actively on the performance of your programme, with your team, for three months.

Quarterly strategy review

At the end of the three-month support period, a comprehensive strategy review — covering programme performance against benchmarks, the full A/B test log and learnings, list health analysis, recommendations for the next quarter, and a clear roadmap for what to prioritise next. Whether you continue with a FlowFixer subscription or take the programme fully in-house, you leave with a clear picture of where you are and exactly where to go next.

The three-month support period starts from programme launch, not from engagement start. You get the full value of the support period against a live, active programme — not a partial engagement while the build is still in progress.

How it works

01: Discovery & full programme architecture

An in-depth discovery session covering your brand, customer data, product catalogue, purchase patterns, loyalty ambitions and eCRM goals — used to design the complete programme architecture before anything is built.

02: Foundation & core build

Template, core flows and segmentation launched first. Your programme is generating revenue from week one while the extended build runs in the background.

03: Extended automation & loyalty build

The remaining flows, loyalty integration, A/B testing framework and predictive segmentation are built in structured phases with milestone reviews throughout.

04: Full launch & handover

End-to-end QA, programme walkthrough and full documentation. Your three-month support period begins from this date.

05: Three months of active support

Monthly planning sessions, async support, A/B test monitoring and flow optimisation — with a quarterly strategy review and roadmap delivered at the end of the period.

Who this is for

  • Scaling brands that need the full programme built and actively supported, not just delivered and handed over
  • Shopify and WooCommerce stores with the volume and product range to justify a complete 10-flow automation suite
  • Brands with an existing loyalty programme (or a clear intention to launch one) that want it properly integrated into their lifecycle automation
  • Marketing leaders who need to demonstrate consistent, data-backed eCRM performance — and want a specialist partner invested in the numbers
  • Brands preparing to move to a FlowFixer subscription and wanting a complete, optimised programme as the foundation

Frequently asked questions

What does the three months of support actually include week to week?

A monthly planning call (60 minutes) to review performance data and agree the next 30 days of priorities. Async access to your FlowFixer strategist for questions, copy review requests and minor adjustments. Active A/B test monitoring with winner implementation and a clear test log updated throughout the period. The support is active, not passive — we come to each planning call with data and a point of view, not just an open agenda.

What loyalty platforms do you work with?

LoyaltyLion, Yotpo Loyalty, Smile.io, Okendo and Stamped — and we can assess custom setups via Klaviyo's API on a case-by-case basis. If you don't yet have a loyalty platform, we'll advise on the right fit for your brand and configure it as part of this engagement.

Can The Ultimate follow on from a previous Launchpad or Accelerator build?

Yes — if you've already completed an earlier package with FlowFixer, we assess what's in place, extend it where possible, and scope the remaining deliverables against what's already been built. You won't pay for work that doesn't need redoing.

What happens after the three-month support period ends?

You'll receive a detailed quarterly strategy review and roadmap. From there, you have full ownership of a comprehensively built, actively optimised programme. Many brands choose to move onto a FlowFixer subscription at this point — benefiting from the same team's ongoing support on a continuous basis. Others take the programme fully in-house. Either way, you leave with a programme that's performing and a clear view of what to do next.

How long does the full engagement take?

The build phase is typically three to four weeks from kickoff to full programme launch. The three-month support period then runs from that date — making the total engagement approximately four to five months from start to the quarterly review. The pace of the build phase is driven primarily by how quickly we receive access to your accounts and brand assets.

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.
