When my family's home was being built in 2012, I would bet that our build would have greatly benefited from the use of WebWiz@rd's email blasting functionality.
This module is a key component in the Digital Plans Room family of modules that we have been evolving over time. Communication is king when you're dealing with many different disciplines across multiple industries, such as any builder is familiar with.
My favourite thing about this module:
Anyone running the Digital Plans Room module through their website can quickly and efficiently send out emails to multiple people in their organization (or across organization units) whenever they need to get a message out. It takes the guess work out of determining who-is-who in the ol' Rolodex.
