Transactional Email

Also known as: Transaction Email, System Email

Transactional emails are automatic messages sent when someone does something on your site or app, like placing an order or resetting a password. They share the key details about what just happened so people are not left guessing.

Transactional email is the quiet background system that keeps customers informed. It includes things like order confirmations, password reset emails, shipping updates, and receipts. The email goes out right after someone completes an action so they are not left wondering what happened. It is usually one person to one message, not a big marketing blast.

These emails matter because people expect them and they actually open them. If your order confirmation or reset link does not arrive, trust drops fast. Good transactional emails reduce support tickets and make customers feel safe using your product. They also help you show a consistent brand experience even in very simple messages.

You can improve transactional email by keeping the subject line clear and the key details easy to scan. Put the main action, like a reset link or tracking button, near the top. Use a friendly tone and plain language so people know exactly what to do next.
