All images that are inserted into an Email Message are hosted by eTrigue. The images live on your DemandCenter account's configured subdomain.
If you are not able to see the images in emails or the images appear as broken links, then it is likely that your company network's DNS servers have not been configured to resolve your DemandCenter's account subdomain. When this happens, you may see issues like the examples below:
Verify That Your Network Properly Resolves Your Subdomain
First, you will need to verify what is the subdomain of your DemandCenter account.
Go to Settings > Account Settings > Site Management. In the list of tracked sites, the domain that has "yes" under the Landing Page column is your subdomain. For example, the subdomain for our own corporate account is "ww2.etrigue.com" as noted below.
Copy or make note of your subdomain. Provide the name of your subdomain to your IT Team or Network Administrators to have them verify that your network resolves the subdomain to the following IP address:
Check If Your Network Connection or Internet is Down
Sometimes if you are not able to see images, then it could also be an indication of a temporary issue on your company network. Your desktop might show an icon to represent the status of your network connection.
In order to see or download the images within an email or DemandCenter, you will need an active internet connection.
Check your computer's network connections. If you require further assistance, contact your IT Team or Network Administrators.
Send an email to an external account such as Gmail, Yahoo, Hotmail, etc.
It is possible that your corporate spam filter blocked or removed the images before delivering the email to you. To confirm whether or not this is the case, send an email to your personal email address (e.g. Gmail, Yahoo, Hotmail, etc.) and see if images appear.
If images appear when sending to an external account, then you may want to speak with your IT Team about your corporate spam filter settings to see why the images were blocked or removed.
