Does anybody know how to personalize a landing page to display firstname and last name, by using query string info (?firstname=XXX&lastname=YYYY) rather than byusing existing contact properties (tokens).
Let's say I have a landing page at domain.com/123 that begins with
What I want to achieve is for anyone that visits this landing page using the URL: domain.com/123?firstname=John&lastname=Smith the first line displays "Hello John Smith," rather than just "Hello"
I suppose it can be done using Java Script. Can anyone help with some ideas?
