Invitations not sent: [failed_quantity]<br/><b>[emails_list]</b><br/>An invitation won't be sent if it has already been sent to that email address before. But if none of your invitations are being sent, and you haven't sent invitations to those addresses before, please make sure that [product] can send any emails at all. If it can't, then the problem is related to [product] or server configuration. In that case, please contact your server administrator, hosting provider, or <a href="https://helpdesk.cs-cart.com/" target="_blank">our technical support</a> to investigate.
