Send reliable transactional emails that reach the inbox

Transactional emails are automated messages sent in response to a user action or a system event. They deliver essential information such as password resets, account confirmations, security alerts, order confirmations, and delivery notifications.

Unlike marketing or newsletter emails, transactional emails are expected by the recipient and are often time-sensitive. Their primary goal is not promotion, but functionality, trust, and immediacy.

Mailpro allows you to send transactional emails in real time using SMTP or a transactional email API, ensuring critical messages are delivered when they matter most.
