If you have any type of a WordPress website that accepts any type of communication. Either via a membership site or an eCommerce store then you site will need to send transactional emails to users. Such examples as, order confirmation emails, password reset emails etc.

By default WordPress is configured to send emails using the PHP mail() function. How ever you may have seen the primary reason why many users search “why isn’t my WordPress site sending emails”

There is a number of problems with the default mail method, and why it doesn’t work.

Many hosting providers do not have this function configured properly. While some hosting providers disable it completely to prevent their servers from being abuse.

As mis-using this function is a common, as it doesn’t require any authentication. And as it can be used to send mass amount of spam.

However, using a WordPress SMTP plugin gives you an alternative way for sending emails that have much better deliver-ability. Simply, using a WordPress SMTP plugin it helps you make sure people get your emails.

So in the short WordPress Wednesday round-up. I will be starting by explaining a little more about what SMTP is and why it is a better solution than the wp_mail() function.

And straight after that I will be posting four of the best SMTP plugins that you can install for your WordPress site.

What is SMTP?

SMTP which stands for Simple Mail Transfer Protocol, this is a protocol used for sending and receiving emails.

So when you send an email, an SMTP server divides it down into its relevant parts and helps send it from your email client to deliver it to your recipient’s email client.

How does it work with WordPress?

SMTP is important to your WordPress site. Like I mentioned above, by WordPress uses the default PHP mail() function to send emails via PHP mail. This means your WordPress site is sending emails via the same server where your site is hosted on.

Which at most part isn’t optimised for sending any emails. It super simple and sorta works but one thing it lacks is authentication.

So you’ll find most emails that get sent by this default function will probably end up in the spam folder or blocked outright by some email providers.

But with SMTP, you can tell your site to send emails via a properly-configured SMTP server. Rather than your site’s server as because the SMTP server is configured to handle sending emails and has the proper authentication in place. And you will see a better chance of making those emails get sent to recipients’ inboxes.

In this WordPress Wednesday post I’ve collected four SMTP plugins that you can use in your WordPress website.

1. WP Mail SMTP

Wp Mail Smtp By Wpforms

WP Mail SMTP is a WordPress SMTP plugin that helps you connect to any SMTP server by entering its details. Or, you can connect directly to the APIs of some of the popular SMTP services such as Gmail, Mailgun, SendGrid, Sendinblue.

The interface of the plugin is well-designed, which makes it clear which options are available to you. And you can also send a test email to make sure your configuration is functioning correctly.

4. Post SMTP Mailer/Email Log

Post SMTP Mailer/Email Log is the next generation and updated version of Postman SMTP. Which was an SMTP plugin that was very popular. Until the original developer stopped supporting it and WordPress.org removed it.

This plugin lets you connect to any SMTP server. And it also includes a great little setup wizard that does an exceptional job of simplifying the setup process:

One characteristic of this plugin is that, when you’ve just entered your SMTP server details, the plugin also helps you connect via API to some popular sending services, including Gmail API, Mandrill API, SendGrid API and Mailgun API.

It also offers many other things like:

  • It is compatible with WordPress Multisite.
  • You can define a secondary fallback SMTP server to use if the primary server fails.
