Thanks for posting. Constant Contact is a permission based company, which is mainly why we do not allow many role addresses to be mailed to. Role addresses are directed to multiple users who may not have given permission. Here is an updated list of Blocked Role Addresses. Having a clean list helps improve your email's deliverability and open rates, which is why you'll want to get get specific email addresses for all of your contacts and remove any role addresses.
We certainly appreciate your feedback and suggest leaving this under our feedback section of the community where it can be viewed by other members and also voted on.
