Direct Send (SMTP relay)

Overview

The direct send feature allows you to send emails directly from the server without using an SMTP server. You can directly communicate with the recipient server and deliver the message. An SMTP relay is a protocol that allows email to be transmitted through the internet, from one server to another, for delivery. It was first created in 1982 and continues to be the internet standard that is widely used today.

An SMTP relay is an email relay service that basically works in two steps:

It receives the outgoing mail from the sender (that is, your amazing Groundhog Day’s email campaign).
It delivers it to the recipient’s local post office, another SMTP server.

Before you Begin
