Email types & metrics
Transactional email
Email triggered by a specific user action and containing information they need as a result — a receipt, password reset, or login alert.
Examples
- Account emails: signup confirmations, password resets and email verification.
- Order emails: receipts, invoices and shipping updates.
- Security alerts: new logins and changed settings.
- Product notifications: a comment, a mention, or a report that finished.
How it differs from marketing email
Transactional email is expected, time-sensitive and usually opened, so it tends to have the best engagement of anything you send. It generally doesn’t need marketing consent, but it must stay transactional. Adding heavy promotion can turn it into marketing mail under the law.

Marketing email
Email sent to promote something — a product update, offer, or newsletter — typically requiring recipient consent and a working unsubscribe mechanism.
Sending & delivery events
Webhook
An HTTP callback your application receives in real time when an event happens — a delivery, open, click, bounce or complaint — instead of polling for status.
Sending & delivery events
Suppression list
A list of addresses your platform will never send to again — populated automatically by hard bounces, complaints and unsubscribes to protect your sender reputation.
