# Transactional Email vs Marketing Email

Understand the different consent, content, and reputation requirements for product messages and campaigns.

Transactional email supports a product action or account relationship. Marketing email promotes offers or content. They need different consent records, sending behavior, unsubscribe handling, and operational safeguards.

## What this means in practice

- Transactional: product-triggered and expected
- Marketing: promotional and consent-dependent
- Different unsubscribe and preference requirements
- Separate reputation monitoring when volume grows

## Implementation checklist

1. Label every message type at the product-event level.
2. Store consent and preferences for promotional mail.
3. Keep password resets and receipts out of campaign workflows.
4. Monitor complaints and engagement by message class.

## Questions teams ask

**Do transactional emails need an unsubscribe link?**

Requirements vary by jurisdiction and content. Product-critical messages are generally treated differently from promotions, but recipients should always have clear support and preference paths.

**Can one domain send both?**

It can, but separate subdomains or streams can help isolate reputation and operational policies.
