If we look at the API doc -
http://apidocs.mailchimp.com/api/1.1/listupdatemember.func.php
It claims that we can "Edit the email address, merge fields, and interest groups for a list member"
But looks like it cannot allow us to updated the email address of an existing subscriber.
Because - it has parameter for the Current Email address of the member.
But we do not have a parameter for the Updated Email address of the member.
So if a subscriber's email address changes, looks like, we had to subscribe that person again as a new record to the list .
Is that correct.
Thanks in advance
