The theme has Google maps integration, so when a user enters in a location during the listing process, it will appear on the listing map, and also on the optional large map you can use on the homepage. The theme does not specifically separate listings into groups by location in terms of showing a list of cities to select from, you would use the search feature to do this. Vantage has automatic emails which are sent when people post listings/events etc, and the WordPress user functionality handles the user accounts in terms of new registration emails and password resets. If you're looking to use a mailing list for manual newsletters though, this is not a feature of the theme. Thanks.
