Customers sometimes have problems associated with comment notifications from WordPress. That is, they have comments turned on, and they have their settings configured to send email when a new comment appears. But they don’t get the email.
And it might not be only comment notifications that don’t get through. Other WordPress notifications, such as new user registration, or password lost and changed, might not get through.
Unfortunately, there isn’t a simple answer. WordPress has its own built-in email feature. But that depends on the underlying email infrastructure provided by the host of your site. If there is something misconfigured in the email setup on your host, you might not get any email from WordPress.
