## Start Here

**New app?**
Start with the [Catalog](./references/transactional-email-catalog.md) to plan which emails your app needs (password reset, verification, etc.), then set up [Deliverability](./references/deliverability.md) (DNS authentication) before sending your first email.

**Spam issues?**
Check [Deliverability](./references/deliverability.md) first—authentication problems are the most common cause. Gmail/Yahoo reject unauthenticated emails.

**Marketing emails?**
Follow this path: [Email Capture](./references/email-capture.md) (collect consent) → [Compliance](./references/compliance.md) (legal requirements) → [Marketing Emails](./references/marketing-emails.md) (best practices).

**Production-ready sending?**
Add reliability: [Sending Reliability](./references/sending-reliability.md) (retry + idempotency) → [Webhooks & Events](./references/webhooks-events.md) (track delivery) → [List Management](./references/list-management.md) (handle bounces).

**Accessibility?**
Most emails fail basic accessibility checks. See [Accessibility](./references/accessibility.md) for `lang`/`dir`, presentational tables, headings, alt text, `<title>`, and contrast.
