NetMail was available with the optional module NetSolutions. NetSolutions is a legacy solution that Blackbaud stopped supporting and maintaining 12/31/15.
NetMail allowed you to create, send, and track email messages to constituents, applicants, students, parents, or faculty/staff. Using Export, you could select the group of individuals to receive the email message, and the fields from the program to include in the message. The export file functioned as a data source in NetMail.
Once you created and sent the message, you could save the file to use again at a later date or to simply help you keep track of the email messages you sent.
