Hello just upgraded to v220.127.116.11:
What the possible usage for this?
You can also pass 'Email' and 'listID' data into the 'Subscribe success page'
%e will be converted into the 'email' and %l will be converted into the 'listID' that unsubscribed.
This opens doors to anything you want to do with the data. Like write a script to send an email notification to yourself that someone subscribed. Pass the data to another application through another application's API. And so on.
