Non Visual solution but this is a bit of code I wrote to attach printed PDF's to an email with a subject and recipient in outlook. It just calls outlook.exe and uses the command line arguments built into it. They have pretty good documentation regarding the different arguments you can use. You would want to obviously replace the variables I'm using in the strcat to whatever suits your needs.
(setq outlook "C:\\Program Files (x86)\\Microsoft Office\\root\\Office16\\OUTLOOK.EXE") ;Change to YOUR Outlook installation directory
(startapp (strcat (chr 34) outlook (chr 34) "/c ipm.note /a " (chr 34) trgfile (chr 34) "/m "(chr 34) "mailto:" recipient "?subject=" customer " - " (strcat dwgname rev#) "&body="(chr 34)))
This won't automatically hit send, but it will open the email and fill out all the fields or attach files so that all you have to do manually is click 1 button.
