## Response

Subject: Apology for Late Delivery – [Project Name]

Dear [Client Name],

I sincerely apologize for missing our agreed delivery date. This delay resulted from an internal process failure on our end, and I understand the frustration this has caused you.

We take full responsibility for not meeting the commitment we made. You relied on us, and we fell short.

Here's what we're doing immediately: [Choose one concrete action: "We've reassigned the project to our senior team to expedite completion," OR "We've scheduled delivery for [specific date]," OR "I'm personally overseeing final review to ensure this doesn't happen again."]

I'd like to discuss how we can rebuild your confidence in our partnership. Are you available for a brief call this week?

Again, I apologize for the inconvenience.

Best regards,
[Your Name]

What remedy would be most appropriate for your situation—expedited completion, a service credit, or something else?
