The plugin uses the wp_mail function in Wordpresss to send the admin notifications. Below is a short list of reasons why the emails might not be sent.

  1. Make sure the Send Admin Email option is turned on. It is located in the options section under the Email tab.

  2. The emails are going into your Spam/Junk folder.

  3. The domain name of the admin email address, used in the main Wordpress General Settings, must be using the same domain name as the website domain. ( Example: support@doubleoptinfordownload ). Some email services will reject emails where the from address does not match the originating domain.
