Fix WordPress Not Sending Email – WP Mail SMTP Not Working

If your WordPress site is not sending email, it can be caused by a variety of issues, such as a problem with your email server settings, a conflict with a plugin or theme, or a problem with the server configuration. Here are some steps you can try to fix this issue:

1. Check your email server settings: Make sure that your email server settings are correct and that you have entered the correct credentials for your email account.
2. Test the email server: Try sending an email from your email server, using the same credentials that you have entered in your WordPress site. If you can send an email, the problem is likely with your WordPress configuration.
3. Check for plugin conflicts: Some plugins may conflict with the WordPress email system. Try disabling all plugins, and then re-enabling them one by one to see if that resolves the issue.
4. Check the server configuration: Your hosting provider may have a restrictive email sending policy, or have block port 25, the default port for sending email. Contact your hosting provider to check if they can help you with this issue.
5. Use a plugin: There are several WordPress plugins such as WP Mail SMTP, Easy WP SMTP, and Post SMTP Mailer/Email Log that can help you to fix the email sending issue by reconfiguring the wp_mail() function to use a proper SMTP server.
6. Update your WordPress version: Outdated version of WordPress can cause this error to happen, make sure that you are running the latest version of WordPress.

If you’ve tried these steps and the problem persists, it may be best to reach out to a developer or your hosting provider for further assistance.
