How to Solve WordPress Not Sending Emails Issue

How to Solve WordPress Not Sending Emails IssueWordPress not sending emails is one of the common issues you may encounter as a WP user. This error can prevent you from getting emails from WordPress on important updates or password reset attempts.

Also, if you are using a contact form plugin on your website, you may not receive emails from your users when they try to contact you.

In this guide, we will explain the causes of this issue in WordPress and then show you how to resolve email issues in WordPress.


Why WordPress Fails to Send Emails

WordPress uses a PHP mail function, wp_mail() to handle emails. So if your hosting server is configured to block requests from this server, your WordPress emails may fail to send.

In other cases, your emails may be ending up in the spam folder. This usually happens if you are using a shared IP address on your hosting server. The email service may detect the source as spam, hence storing your messages in the spam folder.

Also, if your contact form plugin is not properly configured, you may end up not receiving emails from your users.

Before troubleshooting the issue, you need to confirm that the emails are not being sent by WordPress. Below we will show you how to test your emails in WordPress.

How to Test Email Server if WordPress is not Sending Email

In case you want to confirm that your WordPress emails are not sending, you can use any of the following methods;

  1. Use the reset password feature to see if WordPress sends a link to reset your password.
  2. Send a message from your contact form.
  3. You can also use the Check & Log Email plugin to check if wp_mail is enabled on your website.

How to Fix Emails Going to Spam Folder

Sometimes emails from WordPress end up in the spam folder. This means your WordPress emails are working but are being read as spoof emails by email service providers. So here are some tips to improve your site’s email delivery.

Whitelist your Email Address to fix WordPress not Sending Emails

If you are using the default PHP mailer on your WordPress site, then your emails may be seen as spam which can affect the Click Through Rate on your email newsletter, and other emails.

You can encourage your users to whitelist your site’s email address so they can see your mail in their inboxes. To do this, users need to add your email as a contact, which tells mail servers to trust your site’s email.

Authenticate your Emails

The easiest way to set up email authentication is to use an SMTP provider to handle your emails in WordPress. Fortunately, you can also use the SMTP service to fix email not sending issues in WordPress.

SMTP is short for Simple Mail Transfer Protocol and is the industry standard for sending emails.

SMTP uses proper authentication to send emails. This means your emails will have high deliverability. Below we will show you how to configure SMTP using the WP SMTP plugin.

Step One – Install WP Mail SMTP Plugin

The WP Mail SMTP plugin overrides the default PHP mail function WordPress uses and replaces it with a secure SMTP server. This will resolve any email not sending issues you have on your WordPress site.

To get started using WP Mail SMTP, you need to install and activate the plugin on your WordPress site. For this, login to your WordPress admin dashboard and then go to Plugins >> Add New.

Add new Plugins page - wordpress not sending emails

On the Search box, enter “wp smtp” and then click on the Install Now button next to the WP Mail SMTP plugin. Activate the plugin after the installation completes.

The plugin has a setup wizard that makes the configuration much faster. For this, go to WP Mail SMTP >> Settings to open the plugins’ settings page.

Step Two – Select an Email Service Provider

The WP Mail SMTP plugin makes use of SMTP for sending emails. So to fix your WordPress not sending email issues, you will need to integrate a third-party SMTP service provider.

There are different options available on the free version of this plugin. We will use Google SMTP for this guide.

To clarify, if you have a google account or a Workspace account, you can use this option as well. On a free Google account, you can send up to 500 emails per day. Which should be enough for most small-scale business owners.

Premium Google cloud users, on the other hand, can send up to 2000 emails per day with the paid plan.

On the setup wizard page, choose the Email Service provider you intend to use. We used “Google / Gmail” in this guide. Select the Google / Gmail option and then click on Save and Continue.

On the next page, you will need to provide your google client ID and API keys to authenticate the service.

This requires creating a web application on the google developer dashboard. It is a straightforward process and does not require writing any code.

Leave this browser tab open and proceed to the next step.

Step Three – Create a Web App

To create your web app, you need to have a developer account. But if you don’t have this, go to the Google Cloud Console website and login/signup using your google account.

Upon login, you will be taken to the cloud console dashboard. You need to create a project before you can have access to the web application tools.

Click the dropdown next to “Google Cloud Platform” on the navigation menu. A popup window will appear showing all the projects on your account. To create a new project, click on New Project.

You need to make your app public before you can use the API keys on the WP SMTP plugin. For this, go to API & Services >> OAuth consent screen from your cloud console dashboard.
