2. Where transactional email fits

Send receipts, reset links, and login codes as soon as someone acts, without open or click tracking.

Transactional

Sent to one person right after they do something, like a password reset.

Marketing

Sent to many people at once, like a newsletter.

Product

Sent automatically as people use your app, like onboarding.

3. Authenticate and monitor your sends

Emails go out from your own domain with no tracking pixels, and you can see what was delivered.
