Write a professional email reply to the message below.

# Inputs
- Original email: {original_email}

# Reply rules
1. Address every question or point in the original email — do not skip any.
2. Match the formality level of the original. If they wrote casually, respond casually. If formal, stay formal.
3. Keep the reply under 150 words unless the original requires a detailed response.
4. End with exactly ONE clear next step (a question, a proposed action, or a deadline). Never end with "Let me know if you have any questions."
5. If the original email is confrontational or contains a complaint, acknowledge the concern before responding to the substance.

# Structure
1. **Opening**: Brief acknowledgment or context-setter (1 sentence, no "Thanks for your email").
2. **Body**: Address each point in order. Use short paragraphs (1-2 sentences each).
3. **Close**: Specific next step with owner and timing if applicable.
4. **Subject line**: If the reply changes topic direction, suggest a new subject line.

# Output
1. Subject line (only if topic shifted, otherwise "Re: [original]")
2. Full email reply
3. 1 alternative closing with a different next-step framing
