Simple Mail Transfer Protocol or SMTP Service. What does it stand for and how to use it?

In this article, we will explain more about different SMTP services and how you can use them to send emails. As you know, here at WPX, we don’t provide bulk sending, so you can use an SMTP service to send out your newsletters.

You can also check our blog article on the topic.

What is SMTP?

Simple Mail Transfer Protocol or SMPT handles your outgoing mail. This protocol allows applications to transmit email messages over the Internet. Your email client connects to your mail server via SMTP and sends the messages.

In short, the SMTP service allows you to prevent spam from being sent via our mail server and it is usually required an SMTP or domain authentication.

Most used SMTP providers

These services work with WordPress using SMTP plugins like WP Mail SMTP (if you want to check how to install and configure it on your site, please click here).

Here we’ll check the most common SMTP providers and what they need to authenticate the domain.

Sendinblue – You need to make an account first and then you’ll get the necessary DNS records via e-mail.

Mailgun – Here you need to use subdomain and DNS records to authenticate your domain.

Amazon SES – Here you need to add an SPF and CNAME records.

How do these SMTP services work?

First, you need registration for the service that you choose, and then they must provide you with clear instructions on what you need to do to authenticate the domain.

In most cases, you need a couple of DNS records to add to your active DNS zone. Every SMTP service must provide you with the DNS records that need to be added.

Here you check the guides for some of the SMTP services (Sendinblue, Mailgun, Amazon SES)
