Which Emails does WordPress Send?

When we talk about websites that need emailing features, they are mainly the ones with public registrations. Such a website is primarily a membership site. These sites require the user to get mails and also confirm them.

So, whenever building this kind of site, it’s obligatory to have email sending services. Generally, these emails are not the same as newsletter or marketing emails. The emails that they send are most of the time are,

  • Emails notifying about comments
  • Emails regarding password reset
  • New user welcome email
  • Admin notification emails
  • Site update notification emails

The emails are not limited to the ones mentioned. There can also be transactional emails. That is why they are pretty crucial for the user.

How Does WordPress do it?

The most common way the developers send emails to the user is by using the WP mail function. This is the native email solution provided by WordPress. While using this function, the emails are sent using the default method.

For example, when a user requests a password reset, the WordPress website prepares a mail and sends it to the host. The mail is a PHP mail that the host receives and sends mail using the Mail Transfer Agent (MTA) system. And then, finally, the mail reaches the recipient’s inbox.

In the case of PHP mailing system, the mail is in most cases transferred to the spam folder. This causes the recipient to miss the mail, and they request again. But the new mail is also treated as spam, and it becomes an endless loop.

What are SMTP Plugins?

A question you might ask right now is what WordPress SMTP is? In short, SMTP or Simple Mail Transfer Protocol is a plugin service for receiving and sending emails. It is mainly a plugin for WordPress that controls the email you send. The parts are relevant to your mail, and it is moved from you to your recipient clients.

Most of the emails that you receive are probably sent using an SMTP server. If one uses the default WordPress mailing service, the emails are sent as PHP mail. Due to this, you are highly likely to miss the mail. That is why SMTP plugins are used.

The mails sent via SMTP servers are correctly configured. This ensures that the emails you send from the WordPress website are not sent to the spam or junk folder.

Why is it Needed?

As it has already been clarified that the default mailing service of WP is not a reliable one. Even when they send transactional emails, these emails may end up in your spam folder. That is why it is better to use some plugins for WordPress to ensure the recipient gets emails to their inbox. This is where SMTP servers come in.

To send a mail using SMTP, you need to use a plugin and also connect to one. This can be done in three possible routes. They are…

First Route: Use the host’s SMTP server, considering it’s available. But not all hosts have the service of email hosting. That is why this route is not that reliable.

Second Route: You can utilize the SMTP servers provided by free mailing media. Such as the servers provided by Gmail, Yahoo, and Hotmail.

Third Route: If you are looking for a more reliable route, then use a third-party SMTP server. These servers are entirely dedicated to mailing services. One of the most popular services is the Mailgun. There are also a few other reliable ones.
