Subject: Class Cancellation Notice

Dear Students,

I hope this message finds you well. I am writing to inform you that our class scheduled for this week has been canceled due to a family emergency. I apologize for any inconvenience this may cause.

To ensure you stay on track with the course material, I will be uploading a recorded lecture this weekend. Please keep an eye on the course portal for the update.

Thank you for your understanding.

Best regards,
