# Email Templates
A practical guide to HTML email: the table-based layouts that render across 50+ clients, MJML for sane authoring, dark-mode handling, testing, and deliverability fundamentals.
## Overview
Email HTML is frozen in ~1999: tables for layout, inline CSS, limited support for modern features. Different clients (Outlook uses Word's renderer; Gmail strips `<style>` in some contexts; Apple Mail is the most capable) demand defensive coding. The sane path: **author in MJML** (component syntax compiling to battle-tested table HTML) or a similar framework, then test in real clients.
## When to use
- Transactional emails (receipts, resets, notifications).
- Marketing newsletters and campaigns.
- Email design systems (reusable components).
