Title: Provide fail-fast bang equivalents for each API call

A first pull-request after our discussion at #4.

Not completely happy with the current code, but it works though! Feel free to change whatever suits you.

I can blindly call `add_emails!` and I will get an exception if the list does not exist, or `delete_list!` will raise an error if the list does not exist as well.
