Wp Mail SMTP Pro is a WordPress plugin that will make sure your e-mails are actually arriving at their destination and are not blocked before. If you wonder why your e-mails are not arriving or being opened at the other end, this plugin can assist you.

Wp Mail SMTP PRO is a plugin that can resolve WordPress e-mail deliverability problems. Your e-mails are not going to be marked as spam. The essence of e-mail marketing is to reach people first with a message. If the message never arrives, it doesn’t really matter if what is written in the e-mail or how perfect it is. No one will read it. Therefore a tool like SMPT PRO is necessary.

Let’s see more.

If you ever started to work as a blogger or marketer or anything that uses emails or computers, you have encountered this term: SMTP.

At that moment, you wished that someone would have explained it in more than one sentence and clearly so that a normal human being could actually understand what it is, even if that human being doesn’t have a college degree or studied internet programming for the past 50 years. Isn’t it?

Due to my bad experience initially, I want to cover the subject well and with simplicity with as many illustrations ( videos and pictures as possible).

It is effortless to understand if you think about a language problem, if you speak English and I speak Italian.

Obviously, we are not going to understand each other. So the SMTP is like a language that all email servers have to speak to understand each other, and thus the email being delivered.

An email server, or simply mail server, is an application or computer in a network whose sole purpose is to act as a virtual post office. The server stores incoming mail for distribution to local users and sends out outgoing messages.

SMTP is the protocol that all computers use to send an email so that it can be received. Short for Simple Mail Transfer Protocol, a protocol for sending e-mail messages between servers.

Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another

In short, is the language used by email servers to talk to each other.

(countable noun )countable noun 
protocol is a set of rules for exchanging information between computers. (Collins English Dictionary)

Almost all of your online activity is made possible through the help of protocols—the special networking-software rules and guidelines that allow your computer to link up to networks everywhere so you can shop, read the news, send an email, and more.

SMTP provides a set of codes that simplify email messages between email servers (the network computer that handles email coming to you and going out).

It’s a kind of shorthand that allows a server to break up different parts of a message into categories the other server can understand. When you send a message out, it’s turned into strings of text that are separated by the code words (or numbers) that identify each section’s purpose.

SMTP provides those codes, and email server software is designed to understand what they mean. As each message travels towards its destination, it sometimes passes through several computers.

As it does, it’s briefly stored before it moves on to the next computer in the path. Think of it like a letter going through different hands as it winds its way to the right mailbox.


Popular email clients like Gmail, Yahoo, and Office 365 are constantly battling email spammers. One of the things they look at is if an email originates from the location it claims to be originating from.

If the proper authentication isn’t there, then emails either go in the SPAM folder or, worst, don’t get delivered at all.

This is a problem for a lot of WordPress sites because, by default, WordPress uses the PHP mail function to send emails generated by WordPress or any contact form plugin like WPForms.

The issue is that most WordPress hosting companies don’t have their servers properly configured for sending PHP emails.

PHP is a server-side scripting language. That is used to develop Static websites or Dynamic websites, or Web applications. PHP stands for Hypertext Pre-processor, which earlier stood for Personal Home Pages. PHP scripts can only be interpreted on a server that has PHP installed

In a few words, the computer servers are just another language that is not compatible with the email servers used today.

The combination of two causes your WordPress emails to not get delivered.


Email delivery and deliverability can be complicated and may, at times, seem part science and part magic. We can start demystifying these concepts first by defining them:

Email delivery is when an email is successfully delivered to the receiving server.

Email deliverability is when an email successfully arrives in the person’s inbox.

It’s possible to have good email delivery but poor deliverability because it landed in a person’s spam folder rather than their inbox.


So, in short, if you have WordPress, you may run into the problem of email deliverability due to the language problem in the web; let’s say WordPress speaks one language, and the email recipient providers do speak another.

For sure, you want to make sure that your emails are arriving in the person, stay out of the spam folders, and are opened.
