ContactMonkey uses link integrity to prevent links from being modified after they have been sent. If links in your ContactMonkey campaign are redirecting to a blank page, this is likely due to previously tracked links added to the email builder.
To prevent this, only use the original URL in the email builder and not any links modified by ContactMonkey trackers or security tools such as SafeLinks or URLDefense.
Example of ContactMonkey tracking URL prefix:
https://contactmonkey.com/api/v1/tracker...
