Settings → Runny on a schedule → Schedule a question.
Every run is kept, so you can compare this week with last week, and so a task that appears to do nothing can be told apart from one that is failing. Press Last answers on any task to see them.
What it will not do
A scheduled run reads and reports. It cannot send anything to your customers, and any draft it happens to produce is discarded.
Chasing customers automatically is a different setting — Reminders — where the messages are ones you approved once and the system stops on its own. That is deliberately not the same thing as an assistant improvising an email at six in the morning with nobody watching.
