An Easy Guide to Fix WordPress User Registration Email Not Sending

As a WordPress site owner, you may allow users to register on your website for a variety of reasons. While WordPress user registration is a core feature, its also possible to allow user registrations through contact membership plugins, contact forms, LMS plugins, and so on

WordPress sends an email to both the newly registered user and the WordPress administrator when a user registration happens. However, if you’re a beginner, you may notice that the WordPress user registration email isn’t sending as it should be.

If you’re facing the same issue, keep reading this article. This article will address why WordPress user registration emails aren’t being sent and how to fix the issue in a few simple steps.


Let’s begin!

Why WordPress user registration emails aren’t being sent?

If you notice that your WordPress user registration emails aren’t being sent, don’t panic! You’re not the only one. Many WordPress users often go through the same trouble. Why?

There can be three possible reasons:

1. Problem with your web host

WordPress can trigger emails. But it can’t deliver emails without assistance from an email sending service or website hosting. Moreover, WordPress uses wp_mail() to send PHP emails.

Most WordPress users encounter WordPress user registration email not sending issues because their web host doesn’t offer email hosting. On the other hand, some hosting blocks PHP emails even if they have email hosting.

If your hosting doesn’t offer email hosting, your WordPress user registration emails won’t send. If it doesn’t allow for sending PHP emails, your emails will go to spam.

2. Problem with your SMTP server

Another primary cause of email sending failure could be incorrect SMTP server configuration. If your SMTP server is not configured properly, it will raise the spam flag and prevent your WordPress user registration emails from being sent. Authentication and some basic SMTP server settings are part of this proper configuration. 

What is SMTP authentication?

SMTP authentication, also known as SMTP AUTH, is the process by which you confirm to your server that you have the clearance to send emails. SMTP authentication might not be needed for personal email sending, but it is a must for bulk email sending.

3. Problem with your WordPress user registration plugin

There might be some problems with your WordPress user registration plugin too!  Maybe you’re using a contact form or membership plugin; you need to ensure that the plugin is properly configured to send emails.

What is SMTP & why is it important?

The Simple Mail Transfer Protocol ( SMTP ) is the standard for sending emails. The program allows you to send and receive emails by serving as a bridge between the email sender and the recipient.

SMTP aids in the transfer of email from one server to another. It delivers emails from one domain to another. Furthermore, SMTP assists you in fixing issues such as email deliverability, IP blocklisting, etc.

You should use an SMTP service provider because-

  • They ensure a secure atmosphere for sending emails. 
  • They provide you with dedicated IP addresses. 
  • They prevent your emails from going to the spam folder. 
  • Most of them are very easy to navigate.
  • They offer you a lot of customizable email integrations.
  • They come with various effective analytics that will help you keep your emails on track. 

5 easy steps to fixing WordPress user registration email not sending issue

A problem is only a problem till we solve it, right?

If you follow the steps below, you’ll fix the WordPress user registration not sending email issue once and for all!

Let’s dive in!

1. Test your admin email 

WordPress uses your website’s administrator email as the default option when sending necessary notifications such as subscriber registration, password reset, or forget password requests. And the problem usually occurs here!

The administrator email often fails to satisfy the spam filter and is routed directly to the spam folder. They don’t even make it to the spam folder in the worst-case scenario! To avoid this issue, we recommend using a business email address that’s verified by your domain.

What is a business email address?

Well, an email address that specifies your organization is known as a business email address. In general, a business email always includes the organization’s name that is sending it.

For example, if we want to send an email from fluentsmtp.com, we can use himel@fluentsmtp.com as our business email address. 

A business email will not only help you increase email deliverability, but it will also help your branding.

  • Is your administrator email already a business email address? If not, create one by following this tutorial.

    Note: This might vary depending on your Web host. So we recommend looking into your hosting’s knowledge base to create one effortlessly.

Once you’ve created a verified email for your domain, follow these simple steps to change your administrator email address –

1. Go to the setting option on the dashboard of your WordPress website. 

2. Select the General option.
