Dear [Lecturer’s Name],

I hope this email finds you well. I am writing to inform you that I will not be able to attend the certification course scheduled for tomorrow, July 22, 2023.

I apologize for the short notice, but due to unforeseen circumstances, I am unable to attend the session. However, I am committed to joining the CICM certification course starting from this Sunday.

I appreciate your understanding and would be grateful if you could provide me with any materials or information that I may have missed during tomorrow’s session.

Thank you for your attention to this matter.

Best regards, [Your Name]
