We utilize Constant Contact to email these newsletter to everyone. If we have the correct email and you've not "unsubscribed" from it, then you may need to email your Internet Service Provider (ISP). A sample letter is following. Just cut and paste this letter into an email to your ISP, but please remember to replace the XXXX with your information.
To: ISP Customer Support
Subject: Remove Constant Contact Block
Hello. My name is XXXX and I have been a customer of your services since XXXX. I understand that you employ filters and/or blacklists to protect customers like myself from unsolicited email; however, this has made it impossible for me to receive newsletters, announcements, and promotions that I have requested. I value these communications and would like to receive them using this email address.
The sender of these emails uses an email marketing service called Constant Contact. Constant Contact is not an open relay and has strict anti-spam policies in place. Because your filters block emails from Constant Contact I am unable to receive these communications.
I ask that you please help me determine why these emails are being blocked. For further information about Constant Contact or to request more information from them such as log files, the Ops team can be reached at - 781.472.8103 or
.
Mail from Constant Contact can be found with the following characteristics:
"Envelope from:" domains:
@in.constantcontact.com
