Has anyone used Adbobe Sign with SFMC? We are using Salesforce Marketing Cloud (MC) to send email communication to our students who have graduated. We want to now start adding their graduation letter to the emails as an attachment with all their graduation details. A data Extension list in MC has all their info. We would like to use Adobe Sign to auto-populate their info onto each person's PDF and send them each a graduation letter. Does Adobe Sign integrate with SFMC?
