Mr.Walker, one of the developers of Email-Ext has kindly responded to my issue. I am posting his response with his permission so that others in a similar situation can benefit.
Under "Post-build Actions" there is a flat button with the text "Add post-build action" on it. When you click that, what are all the available options? I have a long list of them, including "Editable Email Notification". If you then click "Editable Email Notification", then "Editable Email Notification" will appear under "Post-build Actions." -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
