I’m having an unusual problem with adding a subscriber to my Mail Chimp list. I used to be able to just add an email address and optional first and last name. But now the red asterisk is on the postal address, meaning I must enter the full postal address to add a subscriber. This is not always possible if I don’t have the address. My wife checked her Mail Chimp account and she doesn’t have to enter a postal address. Anyone have any ideas why this has suddenly happened and is there a way I can change it myself?
