I have the following 3 separate lists:
1). District Email (external list) - there are several email addresses and employees for each District #
District #, Emp Email, Employee Name
2). Mail Processor (email enabled list)
Name (App Id), email subject
3). District Values (external list)
District #, App Id
I have created a workflow, that will fire an email to the email addresses in the District Email list when an item is added to the Mail Processor list. Using SharePoint designer, I have selected the action to send an email to; District:emp email using a workflow lookup. I have selected to send an email to the Emp Email address in the District Email list, where District # is equal to District #, in the District Values list, and App Id, is equal to the Name (App Id) column in the Mail Processor list. When I create this lookup I receive a warning that the lookup is not guaranteed to return a single value. I am receiving this error because there is a 1:many relationship between District Values and District email.
Any suggestions as to how to send an email to every email listed on the District email list?
