What Is SMTP?

In a world of digital communication, email has become an integral part of our lives. Whether it’s for personal or professional use, sending emails efficiently is crucial. To ensure the smooth delivery of these virtual correspondences, you might want to utilize tools like SMTP. So, what is SMTP?

SMTP is a widely used communication protocol for sending and receiving emails over the internet. It acts as a relay agent, transferring the email from one server to another until it reaches the intended recipient.

Understanding SMTP

SMTP, which stands for Simple Mail Transfer Protocol, is a communication protocol that plays an integral role in the world of email. It has become the widely accepted standard for sending and receiving emails over the internet. In essence, SMTP works behind the scenes as a digital postal worker. Its primary responsibility is to act as a relay agent, transferring the email from one server to another until it reaches the intended recipient’s inbox.

It’s helpful to think of SMTP as a system of communication between email servers. When an email is sent, the SMTP server processes this email, decides which server to send it to, and then transfers it accordingly. This process repeats until the email arrives at the destination server, which is usually the recipient’s email server.

SMTP in the context of WordPress

If you manage a WordPress website, using SMTP for email transmission is highly advisable. By default, WordPress uses the PHP mail function to send emails. However, this can face deliverability issues, as messages can be perceived as spam by certain email providers.

SMTP offers a more reliable and secure alternative. It sends emails through a designated mail server, unlike the PHP mail function that sends them directly from your web server, which often lacks proper configuration for email transmission. This use of SMTP enhances email deliverability and reduces the chances of your messages being marked as spam, ensuring effective communication from your WordPress site to your users.

The only issue here is that WordPress doesn’t support sending email through SMTP by default. You need a plugin to add that functionality to your site.
