Html Email Designer
I did not find a drag-and-drop email designer UI, so this page describes the implemented Twig-template system rather than claiming a visual builder.
Email Designer: Order Confirmation
How it works in the app
Email delivery is template-based, but it is centered on Twig templates and explicit context variables passed by EmailService and order mail actions. Welcome emails, resets, invitations, ticket messages, contact replies, supplier emails, and order emails all use this model.
I did not find a drag-and-drop HTML email designer or a broad admin UI for editing every template in place, so the strongest implementation is developer-managed Twig templates with operational logging.
Included in the current implementation
Twig-based email templates
Structured template variables
Symfony Mailer delivery
EmailLog rows for order sends
Need email pages that reflect the actual template and delivery stack?
Indexed PIM already uses Twig templates, variable context arrays, Symfony Mailer, and order email logs without pretending there is a visual designer where there is not.
