Don't worry! This article will take you through the top 5 reasons why your WooCommerce email plugin is not sending, and provide practical solutions to ensure that your website's email functionality is back to normal and stable.

I. Unconfigured SMTP: Unreliable default mail system

Problematic phenomena:

• WooCommerce says "Email sent", but the customer doesn't receive it.
• Gmail, Outlook and other mailboxes directly categorize emails as spam or block them

Root Cause:

WordPress Default use PHP mail() function to send emails, and this way it has no authentication, so the emails can be easily judged as spam by the server or directly discarded.

Solution:

configure SMTP(Simple Mail Transfer Protocol) Plugin to ensure that emails are sent through regular mailbox servers. Recommended plugins include:

• WP Mail SMTP by WPForms
• Easy WP SMTP
• Post SMTP Mailer/Email Log

Setup example (WP Mail SMTP as an example):

1. Install and enable the plugin
2. Select the sending method (e.g. Gmail, Sendinblue, Mailgun, SMTP Custom)
3. Enter the SMTP host, port, mailbox account and password
4. Save and Test Send

Second, the mail is intercepted: host restrictions or firewall settings

Problematic phenomena:

• The site is completely unable to send any emails (including backend notifications)
• Mail plugin test also fails

Root Cause:

Some web hosts or servers have disabled the mail() function, or restricted access to SMTP ports (e.g., 587, 465).

Solution:

• Log in to the hosting backend to check if the mail service is supported
• Contact your hosting provider to check whether the SMTP port is open or not
• If the host does not support email, it is recommended to use third-party services such as Amazon SES, Sendinblue, Mailgun, etc.

WooCommerce Mail Setting Error

Problematic phenomena:

• Not sending emails for certain order statuses
• Email title, recipient or content is empty

Root Cause:

WooCommerce MailNotification configurations are not properly enabled or the format is incompletely filled out.

Exhaustion Steps:

• Go to [WooCommerce > Settings > Mail].

• Ensure that all types of email notifications (e.g. new orders, processed orders) are enabled
• Check the inbox, header template and content for completeness
• Validation using test order functionality

Fourth, plug-in conflict: mail plug-ins and themes / other plug-ins are not compatible

Problematic phenomena:

• Email functionality disabled after changing themes or installing new plugins
• Mail styles are messed up or not displayed

Root Cause:

Some themes or plugins may override WooCommerce email templates or block email hooks.

Solution:

1. Switch to the default theme (e.g. Twenty Twenty-Four) for troubleshooting
2. Disable newly installed plug-ins, eliminating sources of conflict one by one
3. Ensure WooCommerce and email plugin versions are up to date
4. Check for overriding WooCommerce email templates in the theme folder

V. Mail logging is not enabled, making it difficult to locate the root cause of the problem

Problematic phenomena:

• No way to tell if an email has been sent or not
• No error messages or logs

Root Cause:

WordPress There is no email log by default, and it is impossible to track when something goes wrong.

Solution:

Install plugins that support mail logging, for example:

• WP Mail Logging
• Email Log
• Post SMTP (with logging)

Through logging, you can clearly view the sending status, time, recipients, and failure reasons of each email, which help to quickly locate the problem.
