No design control
Brevo's templates imposed constraints that broke Ryvdoll's visual identity.
Ryvdoll
Newsletter Studio · France
A custom drag-and-drop email builder built from scratch for a French magnetic fashion doll brand — in one week.
01 — Problem
Brevo couldn't match the brand. So we replaced it.
Ryvdoll is a boutique French fashion doll brand with a precise visual identity. Brevo offered templates, not control. Every modification required workarounds. The brand's aesthetic couldn't survive a generic email builder. The solution wasn't to find a better template — it was to build the tool from scratch and own it entirely.
Modification hell
Every client request meant fighting the platform instead of executing the work.
Platform dependency
Data, templates, and send logic locked inside a third-party tool.
02 — Approach
Audit & Architecture
Mapped full email workflow. Defined block types, template logic, subscriber data structure.
Block Editor
Custom drag-and-drop in vanilla JS — text, image, button, divider, spacer. All reorderable, all editable inline.
Live Preview
HTML renders in real time. Save templates, reload, iterate. Full inline CSS compilation for email clients.
Subscriber + SMTP
Import/export, tag segmentation, direct send via Google Workspace SMTP.

Tool built, fully owned
06 — Status
Built to own. The tool exists.
The studio was built and delivered. The client changed direction — the tool didn't. Built in a week. Costs nothing to run. This is what ownership looks like.
Other projects from this client are covered by NDA.
