Professional Communication
Letters, requests and introductions that must land correctly the first time.
State the purpose early
The reader should know why you are writing within the first two sentences.
One request per message
Correspondence that asks for several things tends to receive a reply to one. Separate them or rank them.
Tone follows relationship
A resignation, an introduction and a request for a reference each need a different distance. Match the register to the person reading.
