Dynamic Lists by constituency

Hi all! We'd like to set up a triggered email using a dynamic list based on a patron's constituency.

Our students, faculty and staff (University Tess User) are automatically added to Tessitura via a custom integration. While it's nice to have their email right away, it doesn't give them a chance to update their preferences or change the automatic password created for them. We'd like to set up a triggered email in Wordfly to run daily to new fac/staff and students welcoming them and asking them to activate their accounts to receive discounted pricing. The problem is, I have no idea how. Is it possible?
