Yes!
You can use Classic Hotspot with Mailchimp (How to send Wi-Fi clients' contacts to a Mailchimp account).
Classic Hotspot pushes data to Mailchimp when a user connects to the Wi-Fi network (it works both for new and returning users).
Through the Mailchimp automation system (for more info:
http://kb.mailchimp.com ) you can trigger emails to all users or to a specific segments (any column in your database can be filtered in order to manage segments).
If you don't use Mailchimp, you have two alternatives:
- you can manually export your contacts to any email marketing tool, in xls or csv format, through the Classic Hotspot Dashboard (dashboard.tanaza.com)
- you can configure push notifications API to push contacts to any 3rd party tool, by building your custom integration.
