I am responsible for the exercises for a graduate course (which happens to contain only international students). The students submit their solutions via email and all of them send a normal email: greeting me and telling that the solutions file is attached then (most of them) wishing me a good weekend as the due dates are Fridays.

One group sends me an empty email: just an attachment without any word! I believe that this behaviour is odd, should I take an action or it is not my business?

Edit: Some have asked why I find this behavior "odd." If these students were submitting their assignments in person, I would find it strange if they just put the assignment on my desk without acknowledging me. Sending the e-mail attachment without any body text seems similarly strange to me.

  • Perhaps wherever you live the culture is different than in my country. When I was in school, it was very common for students to walk to the front of the room before or after class and drop a paper on a pile without saying anything to the instructor. Yes, they MIGHT say, "Have a nice weekend, Dr Jones" or some such. Or they might not, and no one thought anything of it.

I don't really think this is odd: they have been asked to send the assignment by email and they did. There isn't really a need to say anything further and they didn't. Maybe it would be slightly more courteous if they were to add a couple of words of greeting, but your job is not to be Emily Post.

If the assignments were submitted on paper, and they left their assignment in your mailbox, would you insist that they include a note wishing you a nice day? No, that would be silly.

There isn't anything you need to do about this.

When teaching large classes or multiple classes, it can be very helpful if the email, or even better the subject line, contains the key information about the class, section, group and assignment (and possibly TA). It should be the responsibility of the instructor to tell the students what is expected, if anything, in the syllabus and on the assignment itself. Those instructions should make penalties, if any, clear. In the absence of instructions, it is not worth saying anything.

I would be hesitant about imposing penalties mid term, but asking students to include additional information seems reasonable. Just make what you want clear.

    +1 for the practical aspect: maybe this is slightly weird, maybe it isn't, depends on all parties involved. Is the OP entitled to think it is slightly weird? Sure. But the real question is: is it weird enough to intervene by making a course policy about it? If yes: okay, do it; students won't object. If no: let it go. Students -- and people in general -- can be very, very weird. This is small time stuff. Commented Jun 21, 2015 at 19:33

    I'd expect all of this information to be part of the subject line and not the body (there's nothing in the OP that indicates that this isn't done). Adding stuff to the body just forces the recipient to skim quickly over it to make sure there's nothing of importance in it. Wasting everybody's time for no purpose isn't polite in my book. Keeping emails as short as possible (but not shorter!) is one of the core rules of email nettiquette.

Unnecessary courtesies (like greetings) and stating the obvious (like saying that attachment is attached) only waste YOUR time and increase YOUR workload. This might not be obvious at the first sight, but if they all did same that would save YOU considerable time in total. In some company environments this is standard practice, and adding meaningless greetings is what's frowned upon (between close coworkers, like you and your students).

    Saying the attachment is attached is useful if the receiver receives an email without attachment. In that case there's a good chance the professor would hit reply and just type "attachment missing", and the sender fixes the problem, vs. a failed assignment.

    @gnasher729 Yes, of course. But pay close attention at who is benefiting from this correction code and who has to pay for this benefits. It's the student who is benefiting and the professor who has to do this work: read the mail, verify presence of the attachment, verify if the statement matches observed state, take corrective measure (reply). We're talking here about how empty body benefits the professor. Cordial greetings also benefit the student at expense of professor, as it creates more "humane" relationship which will make the professor more likely to explain instead of simply failing.

    Actually, processing an empty mail costs more time for me, as I can grasp at the first glance that an e-mail contains nothing but a minimal text like "Hello, see attached assignment solution. Regards, Alice", while it usually takes me a few moments to realize and become certain that the e-mail client is not currently trying to display or load some complex e-mail content, but that the e-mail is actually empty.

    Asking students to give an email subject or body like, "Chapter 4 homework, Fred Smith" is reasonable. If the assumption is that the homework will be attached, then there's no need to say "attached", but okay, if it makes you feel better. If that's what the instructor wants, he should tell the students, and then if they don't comply, he has reasonable grounds to say "sorry, but your homework was not properly submitted".

You may want to be more forthcoming as to your expectations - if you want text, ask for it. Have a sub section on the homework policy in the syllabus explain that each e-mail should contain the students full name, the class that they are e-mailing you about, the section, etc. such that you can search for the assignments when you grade them, and that any e-mails missing/lacking the information won't be graded and thus the students will receive a zero on the assignment.

I disagree with the other answers. "Hello" and "thank you" are banned from SE sites for reasons of efficiency, but it is far from the norm on Internet. Look at newcomers' first questions for example.

If the assignment had to be submitted in my office, I would be upset if the students were opening the door, dropping the paper on my desk and leaving without a word.

Why emails should be different? Email between students and professors is a formal way of communication (how many questions about ethics and protocol for emails to professors do we have on this site?) and (non superfluous) politeness never hurt.

As for what to answer to students, it is up to you:

  1. You could ignore it
  2. You could tell them you personally found it was a lack of politeness and respect to you.
  3. You could tell them that, although they didn't mean to be impolite and just tried to save time, it may hurt them in later communications. Not spending two minutes to be polite and clearly identify their work (the name of their file may not be as clear as they think - I regularly receive assignments named "Math Homework" by "[email protected]") may be interpreted as a lack of involvement in the project/class.

    '"Hello" and "thank you" are banned from SE sites for reasons of efficiency' - that's only half the story; the other half is that SE is meant to be a collection of questions and answers directed to the public, not a discussion board with personal communication from one user to another user.

Wishing you a good weekend, while perhaps courteous, is also superfluous. However I can see why there might be legitimate reasons for wanting something meaningful in the email body and subject, in addition to the attachment. It would help with sorting and filing emails for example, and empty emails are also more likely to be flagged by spam filters.

I would suggest you make it clear to the students that you require some basic information in the email subject, and body, including student number, course and assignment title etc. Greetings and salutations shouldn't be necessary though.

If an attachment was corrupted in transit for example, or was in an unusable document type, having the basic relevant data in the email body would help to resolve this.


It should be added that automated processing is not unusual now a days. If I am asked to send a specific file, with a specific format, and specific name, to a specific email, it is not far fetched for me to believe that there is a script on the other end which 'processes' the attachment, but ignores the body of the message (uploading it somewhere or sorting it into a folder to view later). Even something as simple as having email rules setup could cause the body to go ignored until a human has to read/grade them. Therefore, it is not unreasonable for students to forgo formal letter formats in a world where a lot of things are automated anyways.

Furthermore, even if there was no automation, some teachers may be trained to see emails with attachments as 'the homework' and ignore it, until they actually grade it. As a result if students included comments or questions, they would go largely unanswered/ignored, and they subsequently would be trained to make it clear when they have questions/comments, and not include those in the 'homework attachment' email, as those dont get adequate responses.

That said, in this case its likely most students probably think the file name is adequate enough to indicate the contents. I.e. if the title says "Homework_Assignment_4 -- Michael_Jones" no other explanation is necessary.


There's an old system administrators' maxim, "Be conservative in what you generate and liberal in what you accept."

It might be thoughtful to add a few polite notes, but just sending the requested homework should be tolerated, too.

I'm working on a technical book now, and my publisher has established certain expectations regarding email, including that email subjects will be rather formulaic (with an identifying string for my specific title, a chapter number, a revision number if appropriate, and "WIP" if I have to submit a work in progress). And both they and I try to add a few words of politeness, but this is not a formal expectation.

I think it's nice that students wish you a happy weekend, but if your biggest problem with your class is that one student is emailing you assignments without niceties, you're doing well.

  • Going a bit off-topic here, but Postel's principle can actually be a terrible idea and the cause of many problems when if comes to standards: you get two implementations tolerating their own deviations from the spec, another ones implements it rigorously, but doesn't work and has to guess what to do in all the possible wrong cases sent by the other implementations.

Definitely this group has more common sense and familiarity with the use of email than most of your students.

First of all, if you have a preference for a given format, information included in subject line or in the text, you should say so. Students are coming from different places, they cannot just figure out of your expectations or preferences.

Second, emails are not letters. The common way of professional emails is similar how the said group used it: brief, contains only necessary information. Most text on professional writing clearly discourage all kind of "Dear XY", "Best regards" and similar. Wishing you good weekend of rehearsing that the attachment is an attachment, and indeed it is what you think is rather unnecessary.

Off course you can have a personal taste different, and you can ask your students to accommodate, but don't expect that your rules are universal or known automatically by everyone.

To answer comments:

Indeed, empty mails are a little extreme. However the closes format to an assignment submission is a memo, and memos does not contain salutation, greetings, or any superfluous "best regards", "is your dog happy?" etc or signature. In other words, memos does not contain anything that OP is explicitly missing.

If one has other preferences, she/he is free to write a guideline or communicate that. For example a page like this: http://faculty.mccombs.utexas.edu/kristie.loescher/assignments/memotips.htm

Comment along the line with Nate's answer, and using his example:

Just for the sake, imagine a similar homework assignment on paper. Do you expect a printed letter like "If it would be a homework assignment, no one would expect an extended intro with "Dear Sir, How was your weekend? I hope you are in good health and enjoy the chirping birds of the Spring. Let me introduce you my solution for the first problem you kingly asked us to solve:" with a big "Should there be any question feel free to contact me. Sincerely, (huge, hand written signature)" at the end? Would you frown upon students who are listing only the answers, no greetings, no salutation as unprofessional and rude behavior because they do not follow standard letter formats (or what you think standard)?

    Downvoted for the blanket claim "Second, emails are not letters." In general, e-mails very much are (the digital equivalent of) letters. The differences are the medium and the transfer mode, not how we fill them with content. Now, it is conceivable that in some cultures on this planet, specific ways adapted to particular contexts have locally overridden the general way to write letters, but then, that needs to be specified.

Sure, you might say hello to a co-worker whom you meet in person, but -- at least in my experience -- it is VERY rare for a business memo to include greetings or well-wishing. They just get to the matter at hand. The bit about the green dress was hyperbole, of course.

If there is some information you need in the email to properly identify it or otherwise to help you sort through your emails, you should tell the students what this is. Like it would be reasonable to say that the subject line or the body of the email should specify the title of the class, the name of the student, and an identification of the assignment, perhaps something like "Chapter 4 questions". I can certainly see saying that you want this in some specified, standard format, so that you can quickly sort through emails and figure out what's what.

But to complain that they didn't wish you a happy weekend ... I suppose it's nice if teacher and students are on friendly terms and exchange such greetings, but if they don't, so what? Are your feelings deeply hurt because a student didn't say "have a nice weekend, Mr M" as he walked out the door? If so, I think you really just need to get over it.

It would be grossly unfair to penalize students for failing to live up to an expectation that you never stated.

The behavior is absolutely OK. The attachment is what it matters, especially if the student has already been introduced to you. If you cannot identify the student, simply ask them to provide their "Student ID" together with their homework. If I would be the student, and somebody would ask me to properly formulate the email, it would look like this:

Dear Mr. MM, highly esteemed Grader,

Today, year 2018 B.C., month of January, day 11, I'm attaching you the homework. It is a ZIP file. The content of the zip, consists of one single file (not to be confused with the zip file itself) called homework.java. Open this file in your favorite editor. This file, although stored as UTF-8, has been carefully typed so that it only contains Latin letters and ASCII symbols. The file has been also scanned for viruses.

Please review my homework at your earliest convenience. Any feedback is welcome.

Yours truly, Me, The Student


Our world is a "behavioral thing" We are all becoming the reasons of some behavior. We can't say for sure, which behavior or which events have led to such situation with your students- and it could be the result of previous matters, which even don't depend on you. Anyway, you've got it and you want to change it. Very simple solution: You can tell to your students that your email internet filters dont allow you to receive empty emails, as well as emails with rudy content. After that- you can start checking only those which are not empty and those which don't have rude content. Belive me- their behavior will change very quickly. Cheerz
