Do you have any restrictions on sending out emails?
Yes, we do have some restrictions. We do not allow sending out more than 200 emails per hour for each domain on our Shared Servers, 500 emails per hour on Premium Servers and 1000 emails per hour on our Business Servers.
Please note all mass mailings must be double opt-in, and we are a strictly zero tolerance for spam hosting providers. If we find a script that is sending out more than it is allowed, that script will be disabled until you contact support.
You can check our Acceptable Use Policy , sections – E-mail and Anti-spam Policy and Use of Email Services.
