HI I have custom list created in one of our anonymous SharePoint 2013 site. List form can be filled by anyone from out side.I have a field called "Customer email" which i have to send initial email as well after approval/rejection email.
I have created a designer workflow in which I have set up "App step" as below
but it is giving me error and the workflow doesn't start
here is the error "RequestorId: 6ba8ff34-935f-e361-0000-000000000000. Details: An unhandled exception occurred during the execution of the workflow instance. Exception details: System.ApplicationException: HTTP 400 {"error":{"code":"-2130242040, Microsoft.SharePoint.SPException","message":{"lang":"en-US","value":"The e-mail message cannot be sent.

Can someone help me out on how to send email to external emails in SharePoint designer 2013 approval workflow.
