Everything you need to know about SMTP server

In this article we talk about the details of email transmission process and SMTP servers. We outline all you need to know about  SMTP.

Simple Mail Transfer Protocol

So SMTP is short for simple mail transfer Protocol which is a common standard for email servers. The SMTP service works to receive and send messages over the Internet. The first SMTP was created about 40 years ago and has evolved greatly over that time.

What is the difference between SMTP server, SMTP relay and MTA?

There are several words related to SMTP that are sometimes be mistaken. But what is the difference between them?
Let’s say you want to send an email to your customer. You prepare the content of the email and write your name and address and the recipient’s. Now on the Internet, this letter is provided by mail user agent (MUA) and the smtp protocol specifies the addresses in the “From” and “To” fields.

The SMTP relay is the part where you send the email and is supposed to reach the SMTP server. Your email is then processed and prepared for delivery to the recipient.

Therefore:

• SMTP server is an application for sending emails. It receives emails from email apps or clients (MUAs) and relays to other servers that can retrieve messages. 
• SMTP relay is a process of transferring between SMTP servers hosted on different domains (Gmail and Yahoo, for example).
• MTA is a sendmail program that processes and transfers emails.

SMTP server or other ways?

SMTP is the primary method of sending emails and is a method used only for sending emails. But there are generally two ways to manage emails sent from your app. Using SMTP server or email API.
But the main function of the email API is not to send emails, and this is just a name to use the HTTP protocol to send your emails. This protocol is mostly used for data transmission in the network. You can choose among the SMTP servers but you cannot choose the API cause it’s a third party service.

Differences between SMTP server and API for sending email:

• SMTP is easier to work with and more suitable for regular sender services
• Email API integration requires coding skills
• SMTP test is easier and is a standalone platform
• App developers and bulk email senders prefer to use the API email
