We have a SharePoint 2010 site in Production.
We are not supposed to deploy any custom code. We should not use SharePoint Designer as well.
We have a Custom List and an Out of the box approval workflow is attached to the list. We have used InfoPath Forms for data input.
The workflow is pretty simple: A requester adds an item to the list (using the infopath forms), an email is triggered to the requester and Approver (name provided by the requester). The emails sent are the default out of the box ones.
Requirement is to modify the email sent to the Requester. Limitations are that we are not supposed to use SharePoint Designer, we cannot create any event Handlers and we cannot edit the default Templates of the emails since the modified email should be triggered only in this case and not globally.
Since this is a single step approval workflow, any suggestions to achieve this without using a workflow and may be by using alerts etc would also help.
