There is a section in the blog with the section heading of "Embedding multiple graphs" that contains information that should answer your question. This section shows how to send two SGPLOT graphs in a single email. It involves specifying multiple graphs in the ATTACH option, such as:

filename sendmail email to=("first.last@company.com") from=("first.last@company.com")
attach=("c:\temp\email1.png" inlined='sgplot1' "c:\temp\email2.png" inlined='sgplot2')
type='text/html' subject="Emailing graphics output";

And then referencing the two PNG graphs later on in the code as CID:SGPLOT1 and CID:SGPLOT2.
