Services
Everything Design Studio.
Nothing Else.
We don't do strategy decks or campaign calendars. We build the actual emails and systems inside Customer.io.
Template Architecture
Modular component systems built from scratch in Design Studio. Reusable blocks, consistent design tokens, and foundations that scale with your team — not against it.
Template Migration
Moving your emails into Design Studio from wherever they live now. Legacy HTML, SFMC, Mailchimp, Klaviyo — we've migrated them all. Pixel-perfect, every time.
Journeys & Automations
Triggered flows, behavioral sequences, transactional emails. We build the logic and the emails that run through it — so your lifecycle program actually works.
Maintenance & Optimization
Ongoing template updates, new component builds, A/B test implementation, and render testing. Your Design Studio instance, always in good hands.
The Platform
Built on Email Design Studio.
Customer.io's visual email builder is the best drag-and-drop editor in lifecycle marketing. We know it inside and out — because it's all we use.
Drag-and-Drop, Done Right
Modular components, reusable blocks, and a visual editor that actually respects your brand guidelines. No more fighting with raw HTML.
Built for Customer.io
Design Studio is native to Customer.io — meaning your templates, data, segments, and journeys all live in one place. No imports, no syncing headaches.

Why Eddy
Don't Just Take
Our Word for It.
Design Studio
Since Beta
We've been building in Design Studio since before it was out of beta. This isn't a side offering — it's the whole thing.
Zero Bloat
No account managers. No status meetings. No SOWs. Just a Slack channel and a request board. Submit work, we build it, you ship it.
Modular by Default
Every template we build is a component system. Reusable blocks, shared tokens, documented patterns. Your team ships faster without us over time.
Real Humans
No offshore teams, no AI-generated code. Actual CIO experts who know the platform cold.
Pause Anytime
Busy month? Full queue? Between campaigns? Pause your subscription and pick back up whenever. No penalty, no guilt.
