How to Fix WordPress Not Sending Email Issue

One of the most commonly asked questions on WPBeginner is how to fix WordPress not sending email problem. Many of our beginner level users ask us why their contact form plugin is not sending emails, or why they are not seeing any WordPress notifications. In this article, we will show you how to fix WordPress not sending email issue.

Why You Are Not Getting Emails from Your WordPress Site

The most common reason for this is that your WordPress hosting server is not configured to use PHP mail() function.

Even if they would allow it to work, many email service providers use a variety of tools to reduce email spam. These tools often try to detect that an email is originating from the location it claims to be originating from, and often emails sent by WordPress websites fail this test.

In such cases, when an email is sent out from your WordPress site, it never even makes into spam folder of the destination. This is why we recommend not using WordPress to send your email newsletter.

This is also the reason why that we recommend using SMTP to send emails in WordPress. SMTP (Simple Mail Transfer Protocol) is the industry standard for sending emails. Unlike PHP mail function, SMTP uses proper authentication which increases email deliverability.

There are many different SMTP services available, but in this article we will show only two that we recommend: MailGun and Gmail.

Sending Your WordPress Emails Using Mailgun

Mailgun is a popular email service provider. They allow website owners to send large amounts of emails with high deliverability.

As a dedicated email service provider, they spend a lot of money and time on making sure that your email reaches its destination.

While Mailgun is a paid service, it offers first 10,000 emails for free every month. That’s more than enough for most folks who just started their blog or website.

Here is how to setup your WordPress site to use Mailgun for sending emails.

First you need to signup on the Mailgun website. After signing up, you need to click on the “Add your domain” button.

Add your domain to Mailgun
