Mail Template Styling

Universally manage and style mail templates sent from Odoo

  • Manage and assign stylesheets (CSS) to Mail Templates, all within Odoo.
  • Optionally strip the original inline-styling during rendering. This doesn't alter the Mail Template body, it's just post-processing during rendering-time. So original Odoo and 3rd party templates stay unchanged.
  • Optionally print the Mail Template ID below the actual message.

Manage stylesheets (CSS)

Menu: Settings / Technical / Email / Template Styles

List stylesheets

Edit stylesheet

Installation notes

A bit of system adminsitration is required
