I've been told by my Email company that I cannot use a colon delimiter " : " as they are “unreserved” characters not safe to use as URL Parameters.
Is there anything else I can put in the REGEX that can replace that? I was given an example of using "~" I cannot seem to get it to work though. Example would be
Would this work?
I'm not quite clear on what your question is. You can swap out the colon with any of a number of characters, including the tilde (~) or an underscore (_), for example, but you'd be doing that in the actual tracking code that gets included in your links/URLs. Then, in the Classification Rule Builder, you'd update your regex to look for the new/alternate delimiter (~, _, etc) instead of the colon.
Perhaps if you can provide more context, someone here can provide more specific, helpful guidance.
