Email templates are ready-made designs you can start from when creating broadcasts. You manage them under Setup → Email Templates, where you can install templates from the Templates Gallery (Mumara's collection, organized by categories like Business, Newsletter, and Ecommerce) or upload your own design as a ZIP file. This feature requires a Commercial License.
Each installed template has two visibility toggles that are often confused: Status is the master on/off switch for everyone, while Enable for Users controls whether non-admin users see the template when creating broadcasts. Both must be on for a template to appear to non-admin users; admins always see all active templates. Row actions let you edit the template's HTML directly (with syntax highlighting) or delete it, and Update Templates re-syncs installed templates with the latest versions in the background while preserving your toggles.
Custom uploads must be a ZIP containing five files at the root level: index.html (the email body), header.html, footer.html, thumbnail.png (the gallery preview), and template.json (metadata such as name, category, keywords, and tags). Optional images/, css/, and blocks/ folders are supported, and relative image/CSS paths are rewritten to absolute URLs automatically.
Worth knowing: uploads fail if any required file is missing or template.json sits inside a subfolder; and editing a template only affects future broadcasts — broadcasts already created from it keep their own copy.
