Why are you not receiving email notifications from your WP site?

Failure to receive emails from your WP site shows that the configuration of your server does include the use of PHP mail () function.

However,even if the server authorizes this function,most email providers use different tools to minimize email spam. In most cases,these tools try to determine the origin of an email,as stated,a test that most WordPress sites fail.

In such instances,any email sent from your WP website does not make it to the spam folder of your email destination. Therefore,it is advisable to avoid sending your email newsletter using WordPress.

Instead,you should use SMTP (Simple Mail Transfer Protocol),which is the set standard to send emails. As opposed to the PHP mail function,SMTP applies effective authentication that enhances email deliverability.
