Have you tried following this method?
To archive and attach the project, select the workspace in the workspace explorer -> right click -> Archive Workspace/ Project. A dialog window pops up as shown in the attached below image. Check the 'Compress Archive(zip)' box and select among the three available ways of archiving (minimal/ complete/ bundle). Select complete if you want to include all the files under the Source's parent directory.
Once you have archived your workspace/project, attach the zip file with your email. Please let us know if this helps you resolve your issue or in case of any further clarifications.
