What all files must be included  to email a simulation report in 2013?

Can you clarify this questions? I'm not sure what report/simulation you are asking about. Are you e-mailing someone the report of a Stress Analysis Results?

If you are, try selecting the .rtf format in the Report Format Dropdown menu of the Format tab in the Report dialogue. This option will will add all the screenshots to a single document that can be viewed in MS Word. 

Hope this helps.
