SMTP Relay


What is an SMTP relay?

An SMTP relay is a protocol of delivering emails from one mail server to another. An SMTP is known as a simple mail transfer protocol. You can send bulk emails through a trusted third party to deliver your emails.

When you send out bulk survey emails, there is an upper limit of the number of emails you can send out. An SMTP relay helps to move your email across networks. It works closely with the MTA (mail transfer agent) to send emails to the right inbox.

Example of an SMTP relay

For example, you need to send out a survey invitation from your gmail account to more than 500 people. Currently, gmail lets you send out only 500 emails. Using an SMTP relay, researchers can send out surveys without being limited by his/her email service provider.
