OK. So here's a scenario: I have a DB table that keeps track of email notifications sent out. There is a column for the address that the email was sent to, and another for the time at which the email was sent. A second table keeps track of replies (e.g. clicks on an embedded link in the email). Feel free to assume additional columns (e.g. unique ids) as needed. When some particular event occurs, I want the following to happen:

1. An email gets sent to a user

2. If there is no reply within a certain time frame, the email gets sent again

3. The above is repeated 3 times. If there is still no reply, a separate notification is sent to an admin account.

That is a common scenario, and trivial to implement as code. Show me how make would help here.
