Depending upon the complexity of your analysis and the different things you are gluing together there may be simple ways or slightly more complex ways. You could consider saving each of the files individually as the mail function supports sending multiple attachments.
mail("address","subject","message", {"fileList1", fileList2"})
If you want a single file you will need to get all the graphs into a single window first. This may be as simple as using a by group if they're all the same type of output and then saving that as a file to mail. Or you may need to save each report and use the display box trick noted here from Craige@JMP that way you can use New Window("title", platform1displayBox, platform2displayBox ...).
