Basic Whitelisting Information

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.

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.

VerticalResponse Domains:
From domain - mail.vresp.com
Bounce domain - cts.vresp.com

VerticalResponse IP ranges:
216.55.172.0/24 
74.116.89.0/24
74.116.91.0/24
74.116.88.0/24
