Workflows in Sitecore are an integral part of the content approval process. The email notification action is an important part of that process, in that it lets content approvers know that something is waiting for their attention. Out-of-the-box implementations of the notification actions only support a single email address to receive the messages. This can be problematic if there is a team of approvers and they all need to be aware of an item pending their attention. In the past, for large numbers of recipients, I’ve set up distribution lists to let all of the approvers receive the message. This can be problematic, though, if only 1 or 2 recipients are needed for multiples actions.
Sitecore support directed me to the following location: /sitecore/templates/System/Workflow/Email action/Data/To. The Validation field for this item contains the regex used to validate the email field and only validates against a single email address.
Sitecore support has registered this as a Wish request and provided the reference number 93362 to use to track the status. I can’t say when this functionality will be available out-of-the-box, but we now have a workaround and it will be included sometime in the future.
