Why WordPress Doesn’t Send Emails?
By default, WordPress uses the PHP mail() function to send system emails or notifications from plugins (e.g., contact forms).
The most common issue occurs when the hosting server is not properly configured to handle this function. For example, if the sender address is @gmail.com but your website domain is www.example.com, this mismatch can cause emails to be blocked by mail providers.
The Solution: Use SMTP
To ensure reliable email delivery, we recommend configuring SMTP (Simple Mail Transfer Protocol). Unlike the PHP mail function, SMTP uses secure authentication, significantly improving deliverability.
- Install a SMTP plugin for WordPress (e.g., WP Mail SMTP, Post SMTP, Easy WP SMTP, etc.).
- Configure the plugin with your SMTP account credentials.
- Test the email sending directly from the plugin interface.
SMTP does not rely on external APIs but uses the standard mail protocol, making setup fast and straightforward.
