You missed the SLA. What you say next matters more.
You breached the SLA. The client knows. You know.
Most MSPs either over-apologise (which makes it worse) or hide behind process language (which makes them angry). The response that keeps the client has three parts: what happened, what you’re doing about it, and what’s changing so it doesn’t happen again.
The scenario:
You need to write an SLA breach response that acknowledges the failure and rebuilds confidence.
The prompt:
You’re writing a response after missing an SLA commitment.
Context: [paste the SLA that was breached, what happened, and root cause]
Write a 150-word email that:
Acknowledges the breach directly in the first sentence (no softening)
Explains what happened in 2–3 sentences (facts, not excuses)
Describes the immediate fix already in progress
States one specific process change to prevent recurrence
Offers a follow-up call to discuss
Tone: Direct, accountable, forward-looking. No grovelling.
