# Email Templates for Newsletter Tiers

This directory contains HTML email templates for the four newsletter subscription tiers:

1. **research-updates.html** - Monthly research insights (scholarly audience)
2. **implementation-notes.html** - Bi-weekly implementation guidance (practitioners)
3. **governance-discussions.html** - Sporadic values/governance topics (stakeholders)
4. **project-updates.html** - Quarterly project milestones (general audience)

## Template Variables

All templates use Mustache-style {{variables}} for dynamic content:

- `{{name}}` - Subscriber name
- `{{unsubscribe_link}}` - Unsubscribe URL
- `{{preferences_link}}` - Preferences management URL
- `{{website_link}}` - https://agenticgovernance.digital
- `{{docs_link}}` - https://agenticgovernance.digital/docs.html
- `{{github_link}}` - https://github.com/AgenticGovernance/tractatus-framework
- Content-specific variables documented in each template

## Usage

Templates are loaded by the newsletter admin UI and processed with a template engine (e.g., Handlebars, Mustache) before sending via email service.

## Design Principles

- Inline CSS for email client compatibility
- Responsive design (mobile-friendly)
- Accessible (semantic HTML, sufficient contrast)
- Brand-consistent (blue gradient header, clean typography)
- Clear CTA buttons with good hit targets
- Unsubscribe link always visible in footer
