Is there a way to set a trigger to generate a mail merge once a field has been checked? I want to generate a donor thank you letter (mail merge document already created and successfully tested) automatically when an opportunity is posted (picklist field). The merged document should be sent to the same user for mailing every time regardless of who closes the opportunity. The closest I have been able to get is to trigger a task for said user to complete the mail merge. I'm hoping to eliminate that step and generate the merged document automatically.
