Emailing a teacher feels weirdly scary, especially when you’re asking for something, like an extension, or admitting something, like you forgot the homework. But teachers get these emails all the time, and a clear, polite one almost always gets a better answer than catching them in the hallway.
Here’s how to write one, plus copy-and-paste templates for the most awkward situations.
How to email a teacher: the 6 parts
Use your school email. It looks more professional and it’s less likely to end up in spam. Many schools ask you to use it anyway.
Write a clear subject line. Say what it’s about: “Question about the essay due Friday,” not “hi” or nothing at all.
Start with a greeting and their name. “Hi Ms. Lopez,” or “Dear Mr. Kim,” with the name they use in class.
Say who you are. Your full name and which class and period. Teachers have a lot of students.
Get to the point. One short paragraph: what happened or what you need. If you’re asking for something, ask clearly.
Say thank you and sign off. “Thank you,” then your full name.

Asking a question about an assignment
Email: a question about an assignment
Subject: Question about the history essay due Friday
Hi Ms. Lopez,
This is Maya Johnson from your 3rd period U.S. History class. For the essay due Friday, should we include a works cited page, or are in-text citations enough?
Thank you,
Maya Johnson
Clear and specific
Asking for an extension
Email: asking for an extension
Subject: Extension request for lab report
Hi Mr. Kim,
This is Jordan Lee from your 5th period Chemistry class. I’ve been sick since Monday and I’m behind on the lab report due Thursday. Would it be possible to turn it in on Monday instead? I can send you what I have so far if that helps.
Thank you for understanding,
Jordan Lee
Honest, asks early, offers a new date
Ask before the due date if you can. An extension request sent the night before sounds a lot better than one sent the day after.
You missed class
Email: after missing class
Subject: Missed class on Tuesday
Hi Mrs. Patel,
This is Sam Rivera from your 2nd period English class. I was absent on Tuesday for a doctor’s appointment. Could you let me know what I missed and if there’s any homework I need to make up? I’ll also check the class page.
Thanks,
Sam Rivera
Responsible, takes the lead
You forgot the homework
Email: forgot to turn something in
Subject: Late homework for Monday
Hi Mr. Garcia,
This is Ava Brooks from your 4th period Algebra class. I forgot to turn in Monday’s homework. I’ve finished it now and attached it here. I understand if there’s a late penalty, and I’ll make sure it doesn’t happen again.
Thank you,
Ava Brooks
Owns it, no excuses
Asking about a grade
Email: a question about a grade
Subject: Question about my quiz grade
Hi Ms. Nguyen,
This is Leo Martin from your 6th period Biology class. I got a 72 on Friday’s quiz, and I’d like to understand what I missed so I can do better on the test. Could I come by during lunch or after school to go over it?
Thank you,
Leo Martin
Curious, not accusing
The key word is “understand.” Asking to learn from a grade goes over much better than asking them to change it. For the bigger picture, here’s how to get good grades without studying all night.
Asking for extra help
Email: asking for help
Subject: Extra help with factoring
Hi Mr. Thompson,
This is Zoe Carter from your 1st period Algebra II class. I’m having a hard time with factoring and I’m worried about the unit test. Are you available for extra help this week before or after school?
Thank you,
Zoe Carter
Honest, specific
Asking for a letter of recommendation
Email: recommendation letter
Subject: Recommendation letter request
Hi Ms. Rivera,
This is Emma Wilson. I was in your AP Biology class last year, and I really enjoyed it. I’m applying to a summer science program and the deadline is March 15. Would you be willing to write me a recommendation letter? I can send you my resume and the program details.
Thank you so much,
Emma Wilson
Polite, gives time and details
Give at least three or four weeks of notice for a recommendation letter, and send a thank-you note after.
Following up when they haven’t answered
Email: polite follow-up
Subject: Re: Extension request for lab report
Hi Mr. Kim,
I just wanted to follow up on my email from Tuesday about the lab report. Please let me know when you get a chance.
Thank you,
Jordan Lee
Short, patient
Wait two school days before following up. Teachers are teaching all day and grading at night.
What not to do
Don’t skip the greeting. Starting with “when is the test” feels rude even if you don’t mean it.
Don’t write in text speak. No “u,” “rn” or “idk.” Use capital letters and full sentences.
Don’t send it at 2 a.m. expecting a reply by 7. Write it whenever, but give them a school day to answer. Some email apps let you schedule it for the morning.
Don’t get angry in writing. If you’re upset about a grade, wait until tomorrow to send it, or ask to talk in person. Dreading the talk at home? Here’s how to tell your parents about a bad grade.
Don’t make up an excuse. Teachers can usually tell, and an honest “I forgot” earns more respect.
Questions people ask
How do you start an email to a teacher?
With a greeting and the name they use in class, like “Hi Ms. Lopez,” then say who you are: your full name and which class and period you’re in.
How do you write a polite email to a teacher?
Use a clear subject line, a greeting, your name and class, one short paragraph explaining what you need, a thank-you and your full name. Use full sentences, no text speak.
How do you ask a teacher for an extension by email?
Ask before the due date, explain briefly and honestly why you need more time, suggest a specific new date and offer to share what you’ve done so far.
How long should I wait for a teacher to reply to an email?
About two school days. If you haven’t heard back by then, send a short, polite follow-up in the same email thread.
