Flexible access to Klaviyo expertise

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.

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.

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.

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.

Yes. FlowFixer is Klaviyo-specialist by design. That focus allows us to move faster, go deeper, and deliver better results than generalist email agencies.

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.

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.

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.

Your subscription covers lifecycle strategy, flow creation and optimisation, segmentation, personalisation, deliverability best practices, reporting, and ongoing improvements, all prioritised around revenue impact.

Both. FlowFixer handles the thinking and the doing. We don’t hand over a strategy deck and walk away, we implement, test, and iterate.

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.

Onboarding is fast. Once you’re live, we audit your account, identify quick wins, and begin working on high-impact flows immediately.

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.

Yes. FlowFixer often complements in-house teams, paid media agencies, and CRO partners by owning the retention and lifecycle marketing layer.

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.
