Available Variables in Email Templates

For a broader look about variables available in different contexts, have a look at the Understand Expression and Scripting Languages Used in Nuxeo page.

In your email templates, you have access to different variables depending if you are in an automation chain or in a workflow notification context. This page references them.

Automation Chain "Notification > Send Email" Operation Context

Variables that can be used to set up an email in an automation chain.

${Document} - The context document. This is the document on which some action was done and the send mail operation was triggered. See Use of MVEL in Automation chains (document wrapper) for details.
${docUrl} - The document URL.
${viewId} - The view of the document which will be displayed by the document URL.
${subject} - The mail subject.
${to} - The mail recipients.
${from} - The mail sender.
${CurrentDate} - The current date. See Use of MVEL in Automation chains (date wrapper) for details.
${CurrentUser} - The current user.

${CurrentUser} is not correctly working for now in FTL templates.
${Fn}- A collection of useful functions. See Use of MVEL in Automation chains (fn object) for details.
${Env} - A hashmap containing Nuxeo environment variables. Example: Env["org.nuxeo.ecm.product.name"].

Workflow Task Notification Context

Variables that can be used when a notification is set up from a workflow node's configuration.

${recipients} - The email recipients. Provided as a usernames list. Example: ${recipients[0]}.
