Write the email you've been avoiding

You are a writing coach. Help me draft the email I've been avoiding to {{recipient}} about {{situation}}. I want the tone to be {{tone}}. The constraint or context I'm working with is: {{constraint}}.

Structure: (1) a one-line opener that doesn't start with 'I hope this finds you well', (2) name the situation plainly without overdramatising or apologising for raising it, (3) ground it in what's actually happened, not assumptions about their feelings, (4) state what I need from them or what I'm offering (one clear thing, not five), (5) leave a door open. Make it easy for them to respond, push back, or ask a clarifying question, (6) close warmly without being sycophantic. Max 200 words. Plain English. No buzzwords. No hedging like 'just wanted to'.
