A use case we came across was needing to send reminders for lease contract milestone dates, which vary by contract. We were able to prototype a solution using project tasks with set durations and finish-start relationships, autocomplete tracking mode, and the notification setting that notifies a user when a task is ready for them to work on.
It "worked" as far as sending out a notification, but the notification emails are not customizable enough for the level of detail we needed to include in the notification.
If you have access to Fusion, you could automate a more detailed notification email to be sent out based on the due date of the task in your project.
