Policies for Mass Mailing and Bulk Emailing
Last Updated: Fri, 01 Jul 2016 > Related Articles
Cox Business allows mass and bulk emailing only when certain conditions are met. These policies exist to reduce spam, fraud, and abuse on the Internet.
About Mass and Bulk Emailing
Mass Mailing, defined by Cox Business Services as Opt-in Mailings, are emails sent to more than 150 users, by either a Cox customer or their third party partner, to any group of end users.
Opt-in means that email recipient signed up for mailings voluntarily. Opt-in implies that the mailing is not spam and a recipient knowingly and willingly requested to receive information via electronic distribution from the originating domain name or business referenced within the content of the email.
Note: Email distribution lists that are purchased from a third party and are represented as opt-in clean lists are not exempt from this policy and will be treated as spam.
Before engaging in Mass Mailings, you must obtain written approval from Cox. Complete the Mass Mailing Request Form. If approval is granted by Cox, you must comply with all instructions and requirements outlined by Cox before engaging in Mass Mailings. Failure to comply with Cox requirements is a violation of the Acceptable Use Policy (AUP).
If Cox denies the request for Mass Mailings, you cannot engage in Mass Mailings.
Mass Mailing is not included as part of any Cox service offering and there is no contractual right to engage in Mass Mailings until and unless a written approval is received from Cox for Mass Mailings.
Cox may approve, deny, condition, or rescind previously granted permission, in its sole discretion. Failure of Cox to reply to customer shall be deemed a denial of Mass Mailing authorization.
