Do you allow bulk emails?
We do not allow unsolicited bulk emails and have a zero tolerence for spam.
If you are sending out mass emails that are legitimate, you may want to let us know so we note your account. If we see numerous emails, we will look into it to be sure it is not spam.
If we receive complaints against your account from ISP's reporting spam, your site will be subject to suspension, so be very careful you are not sending emails unsolicited.
