There’s really no need for ActiveCampaign to “support” it. You can easily do it already with some php or javascript. If you don’t have a programmer, hire somebunny from Fiverr to add the code to your landing page. AC allows you to pass whatever information you have on a contact to a page. The programming on the page can personalize it any way you’d like. http://yourdomain.com/page.php?city=%CITY%&favanimal=bunny
Good workaround, but a link like that can’t be used in a DM piece. And using bit.ly, or similar, on thousands of records would be a bit if a challenge.
