We're adding more power and functionality to contact custom properties in the contacts module.
Soon, you'll be able to create a filtered list of contacts based on logic operators and conditions.
For example, you'll be able to create lists of contacts where region = west coast and status = active.
Once you create your filter, you can save it as a view in the contacts module and use that view as a start point for a text message broadcast. The end result: send the right message to the right people in just a few clicks.
