As Dynamics CRM doesn't support the embedded image, I come to use Workflow(Process) to send out emails. I can select several records under Contact Entity View and Run Workflow to send out emails without any problems.
Now I want to send emails to all Members under a Marketing List.
But for this time, I did it with no luck and an error message of Business Process Error prompted. 
Can anyone please advise how I perform it? Many thanks in advance.
