# Open & click tracking

## Open & click tracking

> Control engagement tracking per send, template, or category.

With tracking on, we inject a 1×1 open pixel and rewrite links so opens and clicks land in the email's event timeline and feed the engagement rates on your dashboard.

### How the default is resolved

Tracking is resolved per send in a clear order, most specific first:

- An explicit tracking flag on the request wins.
- Otherwise the referenced template's default applies.
- Otherwise the category default applies.

> **Sending a receipt or password reset?:** Set tracking to false to deliver a clean, untracked transactional message. Many providers and recipients prefer no pixel on sensitive mail.
