# Email Best Practices

Use this skill when working on email best practices tasks.

## Workflow

- Classify the message type first: transactional, lifecycle, marketing, operational, or support.
- Check consent, unsubscribe requirements, accessibility, content clarity, deliverability, and rate limits.
- Keep secrets, recipient data, and suppression lists out of source and logs.

## Boundaries

- Inspect the target repository before making changes.
- Prefer existing project patterns, declared package managers, and documented validation commands.
- Do not expose secrets, credentials, private user data, or production account identifiers in source, examples, or logs.
- When external APIs or current vendor behavior matter, verify against official docs before implementation.
