The Customer.io person · built in Design Studio

Stand up & run your Customer.io lifecycle

Onboarding to win-back, built in Email Design Studio — Liquid-verified and QA'd across every major email client, light and dark. The person who actually builds the flows. Not someone who hands off to a junior.

Sound familiar?

You bought the tool.
Now it has to work.

Flavor 01

"We bought EDS.
Now what?"

You have Email Design Studio and a blank canvas. You need your lifecycle stood up properly: onboarding, activation, retention, win-back. Not a strategy deck about it. Someone to build the thing, in the tool, this quarter.

Flavor 02

"Our program
is a mess."

Flows exist, but they're inconsistent, slow to ship, or landing in spam. Every send is a fire drill. You need someone to rebuild it right, make sure it lands in the inbox, and keep it moving — without you managing them.

What I do · one path, three steps

Audit → Build → Run.

Start with a free audit. Stand up your lifecycle. Then hand me the keys and I own the channel. Most engagements end up here.

Customer.io Audit

A written audit of your Customer.io setup — account structure, flows, segmentation, and deliverability / inbox placement. Report plus a call. It's free: the no-risk way to start, and it surfaces the real work.

Stand up your lifecycle

Working onboarding, activation, retention, re-engagement and win-back flows — live in Design Studio, Liquid-verified, QA'd across every major email client in light and dark. Built on a reusable foundation, so every future email ships faster and stays on-brand.

Where this goes

Own & run your program

Ongoing flow builds, campaign production, optimization, QA and safe swaps — run against the system, so nothing breaks in a live send. I own the outcome. You stop thinking about it.

How it ships fast & nothing breaks

The engine behind the work.

A senior operator with software that does the heavy lifting. A purpose-built engine rebuilds your templates into Design Studio, verifies the Liquid, QAs every client, and swaps safely in live campaigns — which is how one person moves like a team and never breaks a send.

<table role="presentation">
- <td style="font:14px Arial; padding:8px">
- Hi there, thanks for signing up.
+ <%- component "hero", { headline: ... } %>
+ <%- component "button", { label: "Verify" } %>
</table>

Every block becomes a reusable Design Studio component. That's the reason the next email ships in hours, not days — the craft is invisible, the speed isn't.

Case study

A 30-campaign B2B SaaS lifecycle, moved to Design Studio.

86 templates rebuilt as native EDS components, Liquid verified, QA'd across clients, and swapped into live campaigns without interrupting a single send. One operator, with software covering the rest.

Who this is for

Funded teams already on Customer.io.

Lifecycle, CRM and email leads at funded SaaS or DTC companies that bought Customer.io — or are adopting it now. You want a hands-on senior who builds and runs it himself, not an agency to manage or a junior to coach. You're weighing this against an in-house hire or a stalled rollout — not a $400 template.

✔ Bought EDS, need it stood up right
✔ Program's inconsistent or slow to ship
✔ Sends are landing in spam
✕ Not looking for a strategy deck or a hand-off
