Contact Form Not Submitting the Emails

The most common reason for the emails to not be sent when submitting the built-in Contact Form is that the mail() function is turned off in your server. The first thing is to contact your Host and report the issue. If the mail() function cannot be turned on by your Host the alternative is to install a Plugin that reconfigures the wp_mail() function to use SMTP instead of mail() and creates an options page to manage the settings. This awesome Plugin is WP Mail SMTP Its a very easy and quick configuration that will solve the issue instantly.
