12 C. Etiquette and safety

1. No ALL CAPS (shouting), no "!!", no slang; "Kindly" is fine once — not five times.2. Proofread — the email to a client is the client's sample of your drafting.3. Confidentiality: email is discoverable and forwardable — never write what you would not read aloud in court; mark "CONFIDENTIAL — legally privileged" where genuinely privileged.4. Tone control: reply to the rude message after one hour, not one minute; firm on substance, courteous in form.5. When the thread exceeds ~6 exchanges or grows a second topic — write a fresh email or pick up the phone.
