The list must be a Double Opt-In list. This means a user has subscribed for a newsletter or other email marketing messages by explicitly requesting it and confirming the email address to be their own. Confirmation is usually done by responding to a notification/confirmation email sent to the email address the end user specified. The double opt-in method eliminates the chance of abuse where somebody submits someone else's email address without their knowledge and against their will. You will not be permitted to mail any mailing list that you were given or purchased. In doing so, this will also be considered spamming and may result in termination of the offending account.
Email Scripts must be able to handle and document all information from a double opt-in list. This includes recording the sign-up IP address and date/time, double opt-in verification IP address and date/time, processing opt-outs (via web or email), and list removal on bounce backs. All opt-outs or bounce back removals must be handled in a timely manner, and outbound mail must be throttled on shared packages to a maximum of five hundred (500) emails per hour. If your account is found to be using a script that does not meet these requirements, HostGator reserves the right to suspend, terminate, or deactivate your script or account.
Any unsolicited e-mail being sent will result in suspension or termination of the offending account. We take a zero tolerance stance against sending of unsolicited e-mail and other forms of spam.
