How to Email Your Professor About Missing Class
The good news: this is one of the easiest emails to get right, because it should be short. You're not asking for a favor or making a case — you're just giving a heads-up. Three or four sentences, and the tone is "I've got this handled," not "please rescue me."
The basic template
Subject: Missing class on [date]
Dear Professor [Last name],
I wanted to let you know I'll miss [course name] on [date] due to [brief reason — e.g. being unwell / a family matter].
I'll get the notes from a classmate and review the slides, and I'll reach out if there's anything I need to catch up on. Let me know if there's anything specific I should do.
Thank you,
[Your name]
If you'll miss a lab or exam
Dear Professor [Last name],
I'm sorry to say I won't be able to make the [lab / exam] on [date] because [brief reason].
Is there a make-up option or an alternative I could arrange? I'm happy to provide documentation if needed and to work around whatever works for you.
Thank you for your help.
Best,
[Your name]
Three things that help
- Keep it short. One line for the reason is enough — over-explaining reads as making excuses.
- Show you'll catch up. The sentence "I'll get notes from a classmate" signals responsibility better than any apology.
- Send it before class, not after. A heads-up is polite; an after-the-fact excuse is not.
Most professors just want to know you're not going to fall behind silently. Show that you've got a plan to catch up, and the email has done its job.
