1. Missed Project Deadline
*Subject: Apology for Late Project Delivery – [Project Name]
Dear [Name],
As the project lead, taking full responsibility for missing our agreed deadline on the quarterly report. The delay has likely impacted your team’s workflow, and that’s completely unacceptable.

The report will be ready by tomorrow at 9 AM, and we’ve added specific steps to prevent such delays. These include setting up automated data checks and adding buffer time for quality control.
Please let me know if you’d like to discuss this further. Your project timelines matter, and this won’t happen again.
Best regards,

*Subject: Correction and Apology – [Presentation Name] Data Error
