An action can be configured to send assets to an email recipient.
In the Action properties, go to the Destination asset tab and choose Email with attachment as the destination type.
You can either configure the action to send assets to a preset email address or addresses (separate individual addresses with a semicolon), or allow the user to set his own recipient, in which case he will be presented with a dialog to enter the recipient address when running the action. A message can also be added by entering it in the Message body field.
Additional options that allow user interaction can be set, for example the possibility to rename files and displaying the metadata editor to users when running the action.
If the action is of the Extended type, a metadata macro and additional processing with a processing profile can also be applied.
