On Web Hosting Hub servers, there is a limit per email message of 50 recipients. This recipient limit is the total number of recipients in the To, Cc, and Bcc fields. For example, if you have 25 recipients in your To field, you can only place another 25 recipients total in both the Cc and Bcc fields. Additionally, there is a limit of 250 emails per hour per domain.

If you have a need to send more than 250 emails per hour, you can request an Email Limit Exception through your Account Management Panel. Please keep in mind, that even with an Email Limit Exception, the limit of 50 recipients per email. If you have a need to send out emails to a list of recipients, a mailing distribution program such as PHPList is an efficient way of sending out your emails. Installation and set up instructions for PHPList can be found in our article on How to Install PHPList.
