Basic Whitelisting Information

If you or your members are not receiving test or launched messages, it's possible the receiving mail server is blocking or filtering your message before it's delivered to the inbox. A possible solution is to whitelist our domain and IP ranges so that the server will allow messages through the block.

*Note: Whitelisting is not applicable for major email service providers such as Gmail, Outlook, Yahoo Mail, and AOL due to their large user bases and stringent filtering algorithms.

Below is our whitelisting information. You'll want to provide this information to your IT or website administrator and they can add it to the server so that future messages are delivered to your inbox.
