With the New Report Designer, that was introduced in 2010, documents can now be configured to be emailed.

Yes you could always attach a document to an email from the spooler, but this would attach the whole spool file which was basically useless when it came to sending invoices.

What is now possible in Sage 200 (2010 and up) is the ability to configure the document to be split and sent to relevent contacts. For example a batch of invoices being split up and the customer only receiving their own Invoice.

This is the type of standard functionality that people miss in Sage 200. In truth it is a fundmental part in this day and age. The linked document tells you how to set it up!
