Structure
Sentence 1: Acknowledge. Their concern is real. Don't hedge.
Sentence 2-3: Own the action. First-person. What you'll do. Tonight or by a specific time.
Sentence 4: Deadline. When they'll hear back with an update.
Optional: Context. Only if useful. Never as an excuse.
Example
Sarah,
You're right. The migration broke a workflow we should have tested. I'm on it tonight — pulling the senior engineer who shipped it, plus me on the call.
You'll have an update tomorrow morning, and a fix this week. If we're not on track Tuesday, I'll call you directly.

Why it works
Acknowledgment first defuses the temperature. First-person ownership ("I'm on it") signals seniority. Specific deadline turns abstract anger into concrete patience. Promise of a call if you miss the deadline closes the loop on trust.
