## Response

**Subject:** Apology for delayed delivery

Dear [Client Name],

I want to apologize for missing our agreed delivery date by a week. This delay was due to an internal mistake on our end, and it's entirely our responsibility.

I understand this has caused frustration, and I'm sorry for the disruption to your plans. Here's what I'm doing now: the corrected deliverable is in final review and will be in your hands by [specific date/time]. I'll send a personal confirmation when it ships.

If there's anything else I can do to make this right, please tell me directly.

Best regards,
[Your Name]

Would you like me to adjust the tone or add a specific detail about the deliverable?
