## 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

I’m sorry we delivered your project a week later than promised; this delay was entirely our mistake. We understand how frustrating this is and take full responsibility.  

We’ve now finalized the deliverable and can share it with you by [new concrete date/time] via [channel] for your review. In parallel, we’re adjusting our internal checks to prevent a miss like this in future deadlines.  

If you’d like, I’m happy to jump on a brief call to walk through the work and discuss any impact this delay may have had on your plans.  

Would you like to review the deliverable via email first, or schedule a quick call to go through it together?
