How the wp_mail() Function Works in WordPress

As a WordPress user, you receive a lot of mail from your WordPress site. Whenever a reader posts a comment, a post gets a pingback, or an update is ready for your approval, WordPress automatically sends an email to notify you. You might also get notification emails from your themes and plugins.

Behind the scenes, these emails are all sent using a built-in WordPress function: wp_mail().

The wp_mail() function uses the PHP function mail() to send emails from your website.

The Problem With the mail() Function

The mail() function is a built-in, default PHP function that enables the sending of email.

It’s a very simple, easy to use function — which can actually be a big problem.

The mail() function is also easy for spammers to take advantage of, hijacking it to send hundreds of emails through your website.

In fact, it’s so notoriously hackable that some hosts have even disabled the use of the mail() function altogether.

Why You Need the WP Mail SMTP Plugin

The WP Mail SMTP plugin works by bypassing the WordPress wp_mail() function and forcing it to use your SMTP settings. This means that you can set it to use whatever email you want, just by entering your SMTP options in the dashboard.

Because of the mail() function’s vulnerability to hijacking, the WP Mail SMTP plugin can help to keep your site safe. If a lot of spam emails are being sent from your website, you could get in trouble with your hosting company or get your site blacklisted.

WP Mail SMTP can also come in handy when:

  • your hosting company has disabled the mail() function and WordPress can’t send email
  • your web host’s settings are interfering with the delivery of mail from your WordPress site
  • emails sent from your WordPress website always end up in the spam folder of recipients
  • you want to set up WordPress to send email via Gmail or Google Apps (more on that below)
  • messages sent via your WordPress contact forms never reach your inbox

How to Set Up WP Mail SMTP

After installing and activating the plugin, navigate to Settings » Email to get started.

Here you’ll see the options to set up your SMTP email.
