If the links in your email are not working correctly, there are a couple of issues that may cause this problem:
A. Your CNAMEs were set up incorrectly or not completed.
B. There is some sort of internal block set by your company.
A. Incorrect CNAME
NOTE: This solution is still valid, but ClickDimensions now offers CNAME validation directly in CRM, so this process would only be required if you want more granular information on what is wrong with your CNAME beyond what is provided by the automatic validation.
First click on the link in the email that does not work, then manually replace your CNAME in URL in the address bar with elink.clickdimensions.com or analytics.clickdimensions.com depending on what the link is for (elink for standard links, analytics for web content links and social links). If replacing that takes you to the correct place, then something is wrong with the CNAME. You can test to make sure that is the problem by completing the following steps.
NOTE: If you are on the EU data center, use elinkeu.clickdimensions.com and analytics-eu.clickdimensions.com to perform this test. If you are on the AU data center, use elink.clickdimensions.com and analytics-au.clickdimensions.com.
2. Type nslookup and then your CNAME. For example if your CNAME is link.resgroup.com, you would type "nslookup link.resgroup.com"
3. Then press enter. If the CNAME is correct, the command prompt will display the following result:
If you typed in the CNAME used for your email links, your command prompt should show your CNAME, elink.clickdimensions.com, and www.messagegears.net here. If the CNAME is incorrect, the Aliases will have your CNAME only or an error message will display.
Check your CNAME and refer to this article to set it up correctly.
B. Internal Company Block
If your links do not work when you try to click them, try instead sending the email to an email address that is not within your company network and click the links there instead. If the links work, then there is an issue within your company network rather than with the links themselves. Check your company firewall settings and spam filters, and confirm that your CNAME is also set up within your company's internal DNS settings.
