I need to write a difficult professional email.

Situation:
[What's the situation?]

Audience:
[Who is it for?]

My goal for this email:
[What do you want them to do or understand?]

Relevant history:
[Any relevant history? (optional)]

Please produce:
1. A subject line.
2. A primary email draft using a Clear tone, length: Medium.
3. Two alternative phrasings of the most sensitive sentence, ranging from softer to more direct.
4. One optional opening sentence I could use if I want to acknowledge the relationship first.

Requirements:
- Be specific to my situation — do not write a generic template.
- Keep paragraphs short. Use plain language.
- Do not apologize unnecessarily. Do not sound passive-aggressive.
- If important context is missing, ask up to 2 clarifying questions before writing.

Before finalizing, check that the email gets to the point in the first two sentences and that any pushback is direct but respectful.
