Introduction of SMTP Relay: How SMTP Relay Works?

What is an SMTP Relay?

An SMTP relay is a protocol that allows email to transmitted through the internet. It used for Collecting email from the sender and delivering it to the recipient ’s another SMTP server. It was created in 1982 and continues to be the internet standard that is widely used today.

Sending through an email service provider

So what does this protocol look like when it comes to an Email Service Provider like Mailcot? Businesses that need to send the mass email to their customers use SMTP relay for ease of maintenance and added analytics insights.

A majority of webmail providers like Gmail, Hotmail, Yahoo etc. put a limit on how many Email you can send to different recipients per day to combat spam. As businesses would often exceed this limit, they will require the services of an enterprise level email sending platform. An SMTP relay provider can help businesses and organizations deliver large volumes of email without getting them mislabeled as SPAM.

Email service providers like Mailjet, invest a lot of resources into building their own email infrastructure to handle large volume loads and work closely with the major internet service providers and webmail providers to deliver these emails straight to the recipients’ inbox.

SMTP Service with Advance features

There’s an added layer of value to sending through an Email Service Provider. With Mailcot, before SMTP server sends an email, the system automatically adds link trackers in the body of your message. This then allows you as the user to properly track opens and clicks after an email received.

Mailcot also translates feedback from ISPs (Gmail, Yahoo, AOL etc.), since each one communicates in its own way. Its service saves developers time by converting this into an easily identifiable response, displaying whether an email has either soft bounced or hard bounced. A soft bounce would be if the receiving server was down or full. A hard bounce is if the recipient’s email address is no longer active or mistyped.
