API Key – required to use the Bulk Export function. Where to find it.
Add Account – enter a reference name and API Key to identify the account you are using. The reference name does not have to be the same as the MailChimp account name.
Make Default – if you have more than one MailChimp account, you can make one of them the default account at any time. Queries can be configured to use the default account, so you can run the same macro with different accounts by changing the default instead of modifying every query in the macro.
Delete Account – deletes the selected account from the list.
