When an email is sent from Campaign, a referring URL briefly appears before automatically directing to the final URL.
There is no way to predict what the referring URL will be prior to sending because each URL has different sequential information that is generated at the time of send.
Example of a referring URL:
The link query string components
: Links Domain (Link Farm)
: Click Through Tracking servlet
: Click ID of the link
: Encoded Mailing ID
: Encoded Recipient ID
: Body Type (HTML or TEXT or WEB?)
: Encoded Job ID
: Sending Type (0 is Regular, 1 is Other, 2 is Unknown)
: Recipient Type (normal (0), forward (1), suppressed (2), or seed (3))
