# Email Marketing HTML and MJML
Create email that is beautiful, useful, truthful, reusable, accessible, compatible, measurable, and wanted. Visual impact never overrides recipient consent, transactional clarity, client compatibility, or sender reputation.
## Mandatory workflow
### 1. Classify the message before writing
Classify it as:
- **subscription marketing:** newsletter, promotion, launch, discount, blog/update digest;
- **cold outreach:** individually relevant prospecting with jurisdiction and suppression controls;
- **lifecycle:** welcome, onboarding, nurture, activation, renewal, win-back;
- **transactional:** order, shipping, invoice, password/security, reservation, service status;
- **hybrid:** contains both transaction and promotion—separate it whenever possible.
Do not mix promotion into security, password-reset, receipt, or other essential transactional mail. The message class determines consent, unsubscribe, sender stream, markup, frequency, and copy.
### 2. Gather only material inputs
Infer from supplied brand/site files when available. Establish objective, audience/source of permission, brand rules, offer/evidence, message class, locale/jurisdictions, sender identity, desired action, personalization data, ESP/template engine, sending volume, and required output. Ask only for missing facts that would change compliance, truthfulness, or design.
Never invent prices, discounts, expiry dates, inventory, delivery dates, reviews, customer names, personalizat
