When WordPress stops sending emails, it can quickly become a problem. Contact forms stop working, important notifications disappear, and order confirmations no longer reach your customers. Fortunately, this issue is usually easy to fix once you identify the cause.
In this article, I present the most important checks to perform to get email sending working again on your WordPress site.
Why does WordPress stop sending emails?
By default, WordPress uses your web host’s PHP mail() function. However, many hosting providers limit or block this function to reduce spam risks.
Additionally, mail providers like Gmail, Outlook, and Yahoo have become much stricter about email authentication. A message sent without proper configuration can be rejected before it even reaches the inbox.
- Missing or incorrect SMTP configuration.
- Invalid sender address.
- Misconfigured form plugin.
- Hosting server limiting outbound sends.
- DNS issue related to SPF, DKIM, or DMARC records.
Testing WordPress email sending
The plugin Check & Log Email allows you to send a test message directly from the WordPress admin.
The most effective solution: use SMTP
In most cases, when WordPress stops sending emails, the best solution is to configure an SMTP service.
The plugin WP Mail SMTP is one of the most popular options.
Check DNS records
SPF, DKIM, and DMARC records allow recipient servers to verify the authenticity of your messages.
Check contact forms
Plugins like Contact Form 7 or WPForms may use a sender address that does not match your domain.
