If you host your accounts on your own server on-premise, it will most likely block BuzzBuilder from connecting to it for email delivery. You'll need to involve your IT manager. Here is what you need to do in order to have a campaign sent successfully via your servers:
1. Please ask your IT manager to set up an SMTP Relay for us, and then let us know your STMP Server Name (such as mail.yourcompany.com or smtp@yourcompany.com), as well as the Port number (usually 2525 or 587).
2. Next, whitelist the following IP addresses on your server:
34.208.35.69
35.167.192.125
35.164.5.173
34.212.106.73
35.166.87.99
3. We also suggest that your IT manager whitelist the IP address that BuzzBuilder used to send you email alerts for opens, forwards, links clicked, and website visits. This will ensure these alerts get delivered to your users' inbox. Ask your IT Manager to add the following IP Address: 67.227.87.237

4. One other part you may want to check is that your server is not defaulting. Often times when you set up an SMTP relay, your server will default to only allow communication between those with the same domain as you. If this happens BuzzBuilder cannot communicate with your server. Double check that your server is not doing so and when you are all set up, please contact your client success manager!
