How to auto generate email after the request reached certain period?

Hello All,


Is there any idea or recommendation that allows the system to auto generate email notification to the respective users/recipients reminding that the request has been pending their action for 3days/more days already since the request has been submitted into the system?

Hi! 

You are using BPT ?

Anyway, you can use a "Timer" the action used in the timer can verify how long the request is waiting for user answer and act accordingly.
