Teams running campaigns in Odoo Email Marketing quickly hit the ceiling of the stock building blocks. The default mass_mailing snippet set is generic, brand colors have to be hand-poked into every text block and button, and rebuilding a consistent hero/CTA/footer layout for each newsletter eats hours. When marketing wants a coherent, on-brand system — headers, product grids, testimonial cards, pricing tables, event banners, social footers — the native drag-and-drop editor leaves you copying HTML between mailings and praying the inline styles survive Outlook. That inconsistency is exactly where campaigns look amateur and click-through suffers.

ECOSIRE builds you a productized, brand-tailored theme and snippet library for mailing.mailing. We deliver 60+ email-safe snippets — hero banners, multi-column product/feature grids, image+text splits, quote/testimonial blocks, button and pricing rows, spacer/divider utilities, and RTL-aware headers/footers — registered into the mailing editor so your team drags them in like any core block. The centerpiece is a live color system: a small settings model (extending res.config.settings / a dedicated models.Model) stores your primary, secondary, accent, text, and background colors, and a QWeb/OWL-driven re-theming layer rewrites the inline styles of every snippet on the fly, so switching a campaign's palette is one color-picker interaction rather than a manual find-and-replace. Because Odoo emails must ship inline CSS, every block is engineered with table-based, inline-styled markup and tested against the common clients, not just the web preview.

Technically, this is a proper addon: a clean __manifest__.py declaring the mass_mailing dependency, snippet templates in QWeb XML registered via the editor's snippet options, an ir.model.access.csv plus record rules so the theme settings respect multi-company boundaries, and optional automated actions if you want default templates applied to new mailings. It runs on Community or Enterprise (Email Marketing is available on both; we flag any Enterprise-only touchpoints during scoping) and targets Odoo 17.0, 18.0, and 19.0 with the version you standardize on. Everything is server-side and template-driven — no external CDN calls that would get your images blocked — and the color engine is exposed through the JSON-RPC/XML-RPC API if you want to drive palette presets programmatically.

Delivery is build-to-order: after a short scoping call we confirm your snippet wishlist, brand palette, fonts, and target Odoo version, then design, build, and hand it over — typical timeline one working week from confirmed scope. You get the installable source, staging UAT, docs, and a training session before go-live. Pricing starts from $999 (indicative, single-company base scope); adding bespoke snippet designs beyond the base set, deeper multi-company/multi-brand palette isolation, or additional localization and RTL depth increases the quoted scope. The from-price is indicative — you get a fixed quote after the scoping call.
