## Prompt

Write an apology email to a client. We missed the agreed delivery date by a week due to an internal mistake (not their fault); the client is frustrated. Be sincere, take responsibility, offer a concrete next step, don't grovel. Under 130 words.

## Response

Thank you for your patience with us. I’m sorry we delivered your project a week later than agreed; the delay was caused by an internal error on our side, not yours. I understand this impacted your plans and appreciate how frustrating that is. We have now completed the work and will deliver the final package to you by tomorrow noon. Internally, we’ve updated our review process so this doesn’t happen again. If you’d like, I’m happy to jump on a call to walk through the deliverables and next steps.  

Would you like a version of this email tailored to a specific industry or project type?
