Retain line breaks in emails

Please retain line breaks in the emails we send to project volunteers.

That would make the emails a lot easier to read and organize topics.

Also remove the quotes that appear around the entire message.

Thanks! - Written with a several line breaks. :)

No file, test, or entry point is named. Trace where emails to project volunteers are assembled, then verify that line breaks are preserved and the surrounding quotes are removed in the sent message.
