Subject: Apology for the Delay on Your Project Hi Sarah, I want to sincerely apologize for missing the deadline we agreed on for the homepage redesign. There's no excuse — I underestimated the review time needed and should have flagged it sooner. I'll have the completed files to you by end of day Friday, and I've blocked extra time this week to make sure it doesn't happen again. Thank you for your patience. Best, Alex
Subject: Our Apology for the Billing Error Hi Jordan, I'm sorry about the duplicate charge on your account last week. I understand how frustrating that must have been, especially without a quick explanation from us. I've refunded the extra charge in full — you should see it in 3-5 business days — and added a $10 credit to your account for the inconvenience. Please let me know if there's anything else I can help with. Best regards, Support Team
Yes. Vague language like "mistakes were made" reads as evasive. Clearly stating what went wrong and that it was your responsibility builds more trust than hedging.
Usually 100-250 words is enough. State what happened, take responsibility, and explain the fix — then stop. Padding it out can make it feel less sincere.
For minor issues or when the recipient is remote, email is fine. For serious mistakes with close colleagues or major clients, consider a quick call or in-person conversation followed by a written summary.
