Customer.io Consultant

I fix the data layer, journey logic, and CRM execution inside Customer.io so your lifecycle actually performs. Based in Amsterdam, I work hands-on with growth and product teams to turn a messy instance into a system that drives activation, retention, and revenue across email, push, SMS, and in-app.

The Problem

Teams buy Customer.io because they need lifecycle messaging. Then reality hits. The event taxonomy is a mess. Attributes get duplicated or never sent. Segments rely on guesswork instead of real behavioural data. Triggers fire at the wrong time, or not at all.

Attribution is broken, so nobody trusts the dashboards. Campaigns default to batch blasts because the data isn't clean enough for anything smarter. The team loses confidence in the tool, and Customer.io becomes an expensive email sender instead of a lifecycle engine.

This isn't a platform problem. It's an architecture and execution problem. And it doesn't fix itself with another campaign or a new template.

The Solution

I provide senior, embedded help — not junior campaign production. I sit between your product, engineering, and marketing teams to fix what's broken at the foundation level.

What gets addressed first depends on where the damage is, but the pattern is consistent:

  • Data model — clean up the event schema and attribute structure so segments and triggers work reliably
  • Event map — define which events matter for lifecycle stages and make sure they're actually being sent
  • Identity resolution — fix merge issues, anonymous-to-known handoff, and profile hygiene
  • Core journeys — build the flows that move the needle: onboarding, activation, retention, win-back
  • Measurement — set up conversion tracking and reporting you can trust
  • Deliverability — IP warming, domain authentication, sending reputation
  • Governance — frequency caps, opt-in management, suppression rules

The goal is a Customer.io instance your team can operate confidently — not one that depends on me forever. I document everything, train your people, and hand it off clean. If you want the full methodology behind this, the CRM Implementation Playbook covers the framework in detail.

What I Help With

  • Customer.io implementation planning — scoping the project, defining milestones, aligning stakeholders on what "done" looks like before any build starts
  • Event and attribute architecture — designing the tracking plan so your data is structured for segmentation, triggers, and reporting from day one
  • Journey strategy — mapping the lifecycle stages that matter for your business and deciding which flows get built first
  • Activation, retention, win-back, and lifecycle optimization — building and refining the campaigns that move users through each stage
  • QA, reporting, and experimentation — testing flows before they go live, setting up dashboards, and running structured A/B tests to improve performance
  • Team enablement and documentation — training your team to manage the system independently, with clear docs on naming conventions, flow logic, and escalation paths

This maps directly to how I run CRM implementation projects — the same rigour, applied specifically to Customer.io.

My Approach

Step 1: Audit current setup — I review your Customer.io workspace, data layer, existing flows, and deliverability metrics. This surfaces the biggest gaps and the highest-leverage fixes.

Step 2: Map lifecycle stages and business events — I work with your team to define the stages that matter (signup, activation, first value, retention, churn risk, win-back) and the events that signal transitions between them.

Step 3: Design journey architecture — I create the blueprint for which flows handle which stages, how they interact, and what data they require.

Step 4: Prioritize highest-leverage flows — Not everything ships at once. I rank flows by expected impact and build the ones that drive the most revenue or retention first.

Step 5: Launch, QA, measure, and iterate — Flows go live with proper QA, conversion tracking, and a test plan. Then we iterate based on real data, not assumptions.

Proof of Approach

I've built and fixed Customer.io setups for fintech companies managing compliance-sensitive onboarding, ecommerce brands running multi-market lifecycle campaigns, and product-led growth teams that needed event-driven activation flows to replace batch emails.

The work spans the full stack: data architecture, journey design, deliverability, and team enablement. I'm a Customer.io Certified Partner, which means I've been vetted by the platform team and stay current on product changes, API updates, and best practices.

I don't show fake logos or claim inflated outcomes. If you want specifics, the results page has real examples. And if you're evaluating whether Customer.io is the right platform for you, I'll tell you honestly — even if the answer is something else.

Who It's For

This is for teams that have outgrown their initial Customer.io setup, or that are starting fresh and want to get it right the first time:

  • SaaS — activation and retention flows tied to product events
  • Fintech — compliance-aware onboarding and transactional lifecycle messaging
  • Subscription businesses — churn prevention, renewal nudges, and expansion revenue
  • Product-led teams — event-driven messaging that responds to what users actually do
  • Ecommerce brands with advanced lifecycle needs — beyond basic abandon cart, into replenishment, loyalty, and cross-sell

Not the right fit? If you're looking for someone to send a weekly newsletter and manage a basic email list, that's not what I do. This is for teams that need the data and journey layer fixed properly. For ongoing strategic support beyond the initial build, take a look at the Ongoing Growth Partnership.

FAQs

Do you work only in Customer.io?

Customer.io is my primary platform, and it's where I go deepest. I also work with Braze and Klaviyo when the project calls for it. If you're unsure which platform fits, I can help you evaluate that before committing to a build.

Can you help if our tracking is broken?

Yes — that's one of the most common starting points. I audit the event layer, identify what's missing or malformed, and work with your dev team to get the right events flowing into Customer.io with the correct attributes.

Do you write the flows too?

I design the journey logic, write the copy for key flows, and build them inside Customer.io. For larger teams with dedicated copywriters, I provide the structure and they write within it. Either way, flows ship complete and tested.

Can you work with our developer or data team?

That's the normal setup. I sit between marketing, product, and engineering to make sure the tracking plan gets implemented correctly and the data reaches Customer.io in a usable shape. I speak both languages.

Is this project-based or ongoing?

Both options are available. Most engagements start as a focused project (audit, architecture, core flow build) and some continue into ongoing optimization. There's no lock-in — I scope it based on what you actually need.
