Sending messages through the SMTP relay

Transactional emails are automatic messages sent in response to a subscriber’s actions. Subscription or booking confirmation, order updates, notifications — these are all examples of transactional emails.

To send transactional emails via SMTP, enter a server address, port, login, and the password of your SendPulse account into your application.
