Whitelist our emails
Our email newsletters are sent out by Constant Contact. If you want to ensure that you will receive all of the news, please “whitelist” our address.
If you did not receive an email that we sent to you with Constant Contact, look in your spam, junk, or bulk folder for the email.
If it is not there, your Internet Service Provider (ISP) may be blocking one of Constant Contact’s IP addresses.
To make sure that all the IP addresses are being accepted by the contact’s Internet Service Provider (ISP) you will want to have them whitelisted by the ISP. This should resolve the issue.
Letter to request whitelisting by your ISP
To: ISP Customer Support
Subject: Remove Constant Contact BlockHello. 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 ops@constantcontact.com.
