Email Theme Module Documentation

An Email Theme contains the global CSS stylesheet and typography rules applied to your transactional email communications. It standardises font families, container widths, color palettes, call-to-action (CTA) buttons, and element padding across all outgoing emails.

How it works

1. Create an email theme — define a unique name, description, and status for your design theme.
2. Customise CSS rules — write custom CSS inside the style field to style .container, .content, .field-table, .message-box, .cta-button-primary, and other template components.
3. Inject into emails — the platform compiles theme styles directly into your rendered Email Templates during transactional delivery.
