After you introduce why you're writing, you need to add more details and supporting information, so that your reader understands the situation you're describing.
I once had an employee who was very careless-he made tons of typons on every page of the reports he wrote and also sometimes sent e-mails to the wrong people.
Gear up, dive down, slip the note into the red mailbox sitting on the ocean floor, and according to Mr. Nakanishi, it will actually get to its destination.
The email to a colleague of the sport's governing body, the IAAF, suggests delaying naming Russian drugs cheats as long as they were not competing to spare embarrassment ahead of the 2013 world championships in Moscow.
My recommendation is just take it a step further and include exactly what you need the recipient to do and the estimated time it takes for them to do it.
