Send Email to user after click submit button Currently I am doing a recruitment system using Drupal 7 where the applicant can apply the job and HR admin can shortlist the applicant.

I have created a "shortlist button" in the content type to let the HR admin change the applicant status from pending (by default) to shortlisted. I put some rules to change the user status.

So my question is: How can I send the email to notify the user after the HR admin clicks the "shortlist button" to inform the user that they has been shortlisted?
You are looking for Workbench email module.


  Provides a way for administrators to define email transitions and
  configurable email subject / messages between those transitions. Email
  transitions can be defined as when content moves from state to state.
  Based on those email transitions, configurable emails can be created /
  updated / deleted as the site admin see's fit.
