You reach the bottom of a professional email and see something unfamiliar just above the sender’s name:
R/S,
John
If you have never worked in a military, government, legal, or highly formal environment, those two letters can be surprisingly confusing.
So, what does R/S mean in an email? When it appears as an email closing, R/S most commonly means “Respectfully Submitted.” It is a polite, formal sign off associated particularly with military style and official correspondence.
The meaning becomes less certain when R/S appears inside a sentence rather than before a signature. Like many abbreviations, the surrounding context matters.
There is another important distinction. You may also encounter R/ for “Respectfully” and V/R for “Very Respectfully.” Official U.S. Navy and Air Force materials show V/R being used as a professional email closing, while Department of Defense correspondence also provides real examples of R/S appearing at the end of messages.
Understanding these differences helps you read formal emails correctly and prevents an unfamiliar sign-off from looking more mysterious than it really is.
What Does R/S Mean in an Email? Quick Meaning
In an email signature or closing, R/S usually stands for “Respectfully Submitted.”
It functions as a courteous way to end a message, particularly when the sender is submitting information, making a formal request, or communicating within an organization that uses military style correspondence conventions.
A military-affiliated terminology guide from Wayland Baptist University specifically lists R/S as “Respectfully Submitted” and describes it as an ending greeting used in written communication or email.
The most useful interpretations are:
- R/S = Respectfully Submitted the main email-closing meaning.
- R/ = Respectfully another concise formal closing.
- V/R = Very Respectfully a closely related sign-off frequently seen in military correspondence.
- R/S inside a sentence may have another meaning and should be interpreted from context.
For example:
“Please find the requested report attached. R/S, Michael”
Here, R/S means Respectfully Submitted.
“Thank you for reviewing my request. R/S, Capt. Lewis”
Again, it functions as a formal closing.
“I’ll forward the final version this afternoon. R/S”
The sender is ending the message respectfully rather than introducing another piece of information.
Origin & Background
The language behind R/S comes from traditional formal correspondence.
Long before email became the normal way to communicate at work, professional letters ended with established complimentary closings. Expressions such as “Respectfully,” “Respectfully submitted,” “Sincerely,” and “Yours faithfully” helped signal courtesy and the relationship between the writer and recipient.
As communication moved from paper letters and memoranda into email, some traditional language survived in shortened form.
That is where expressions such as R/S and V/R fit naturally.
Military communication is particularly relevant because rank, protocol, and professional courtesy have historically influenced how correspondence is addressed and closed.
Official U.S. Air Force leadership guidance, for example, advises using “Very respectfully” or “V/r” when communicating with superiors. A U.S. Navy acquisition workforce guide likewise identifies “Very Respectfully” or “V/R” as an appropriate abbreviated closing in subsequent email responses.
R/S is also visible in actual Department of Defense email correspondence, where messages have been closed with “R/S,” demonstrating that the abbreviation is used in real professional communication rather than existing only as a dictionary definition.
However, R/S is not a universal business-email standard.
Someone working in marketing, technology, retail, education, or a creative agency may go years without seeing it. Someone working around military personnel, veterans, government offices, or formal administrative processes may encounter it much more often.
That difference explains why the abbreviation can feel completely normal to one reader and unusual to another.
Real Life Conversations
Because R/S is primarily an email expression, people often encounter it first and then ask about it through more casual platforms.
WhatsApp Conversation
Person A:
The client replied to my email with “R/S” before his name.
Person B:
Respectfully submitted.
Person A:
Oh 😭 I thought it was some department abbreviation.
Person B:
No, it’s basically his sign-off.
Here, the confusion comes from treating R/S as part of the email content instead of recognizing it as a closing.
Instagram DM
Person A:
Random question. What does R/S mean at the end of an email?
Person B:
Usually “Respectfully Submitted.”
Person A:
That makes much more sense. The sender is military.
Person B:
Yeah, you’ll see formal closings like that more in those environments.
The sender’s professional background gives an important contextual clue.
TikTok Comments
Person A:
POV: your new supervisor ends every email with R/S and you have no idea what it means 😭
Person B:
Respectfully Submitted.
Person A:
I genuinely thought he was telling me to reply soon 💀
This reflects a common feature of abbreviation confusion: people invent a meaning that seems plausible when they have never seen the actual expression.
Text Message
Person A:
Would it be weird if I signed my email “R/S”?
Person B:
Who are you emailing?
Person A:
A regular corporate client.
Person B:
I’d probably just use “Best regards” unless R/S is normal in your organization.
That is good practical advice. Correct language can still feel out of place when it does not match the communication culture.
Emotional & Psychological Meaning
R/S communicates more than a literal phrase.
It signals respect, formality, professionalism, and restraint.
Email closings perform an important social function. They help soften the ending of a message and show how the sender wants the relationship to feel.
Compare:
“Send me the updated document tomorrow.”
with:
“Please send me the updated document tomorrow.
R/S,
Daniel”
The actual request is nearly the same, but the second version deliberately signals professional courtesy.
This becomes especially important in environments with clear hierarchies.
People often become more careful with wording when writing to a commanding officer, senior manager, government official, professor, or another authority figure. A respectful closing can reinforce that awareness without adding another full sentence.
A situation I have seen repeatedly in professional communication is someone becoming worried because a short email looks emotionally cold.
They receive:
“Approved. Proceed as discussed.
R/S,
James”
and wonder whether James is annoyed.
Usually, the closing itself should not be read that way.
Concise professional communication can simply be efficient. R/S actually adds a layer of courtesy even though the overall message remains brief.
That is a useful lesson in email psychology: short does not automatically mean angry.
Usage in Different Contexts
Social Media
R/S is not common everyday social-media slang.
You are unlikely to see friends ending Snapchat messages or TikTok comments with “R/S” unless they are joking, imitating formal correspondence, or discussing military communication.
On social platforms, people are more likely to encounter R/S while asking what an email they received means.
Friends & Relationships
R/S would sound unusually formal between close friends.
Imagine receiving:
“Dinner at eight sounds good. R/S, Ahmed.”
Unless the sender is deliberately being funny, it sounds like a business memo.
Friends usually use:
“See you,”
“Thanks,”
“Take care,”
or no closing at all.
Work / Professional Settings
This is where R/S makes the most sense.
It can fit naturally in organizations where “Respectfully Submitted” is already an accepted correspondence convention, particularly military-connected or highly formal environments. Military-affiliated terminology references explicitly document this use.
However, ordinary corporate email often favors more universally recognizable closings such as:
Best regards,
Kind regards,
Sincerely,
Thank you,
If your organization does not normally use R/S, spelling out “Respectfully submitted” may be clearer.
Casual vs Serious Tone
R/S naturally creates a serious or formal tone.
“Attached is the requested documentation. R/S, Sarah.”
sounds professional.
By contrast:
“That meme was hilarious. R/S, Sarah.”
sounds intentionally over-formal and therefore humorous.
The meaning has not changed. The mismatch between the formal closing and casual message creates the joke.
When NOT to Use R/S
Do not use R/S simply because you want an email to sound sophisticated.
Professional communication works best when the reader immediately understands it.
If you are writing to international clients, general consumers, younger employees unfamiliar with military-style abbreviations, or people outside your organization, “Best regards” will usually be clearer.
Avoid R/S in highly casual communication unless you are intentionally joking.
It may also be inappropriate to copy military communication habits merely because you have seen someone else use them. Different organizations have their own etiquette.
Cultural sensitivity matters too.
A closing that feels normal within an American military environment may be unfamiliar to a business professional in Saudi Arabia, Pakistan, Japan, France, or another country.
When writing across cultures, clarity usually matters more than abbreviation.
Finally, avoid R/S if you are not actually sure what it means in your specific organization. Internal abbreviations sometimes develop specialized meanings.
When context contradicts “Respectfully Submitted,” ask rather than guess.
Common Misunderstandings
A frequent mistake is reading R/S as “Regards/Sincerely.”
That interpretation feels logical because both words are common email closings, but Respectfully Submitted is the established expansion documented in military-oriented references.
Another mistake is confusing R/S with V/R.
They are related but not identical:
R/S = Respectfully Submitted
V/R = Very Respectfully
Official Navy and Air Force materials specifically document V/R or V/r as shorthand for “Very Respectfully.”
Readers also sometimes assume that R/S indicates anger because it is short.
It does not.
A sender may simply be following an established professional convention.
Finally, remember that R/S only strongly suggests “Respectfully Submitted” when it appears as a closing.
If you see:
“We need the R/S numbers by Thursday.”
then “Respectfully Submitted” obviously does not fit. R/S could be organization-specific shorthand or have an entirely different technical meaning.
Placement is one of your strongest clues.
R/S Compared With Similar Email Closings
| Expression | Meaning | Typical Tone | Best Use |
| R/S | Respectfully Submitted | Formal, respectful | Formal or military-style correspondence |
| V/R | Very Respectfully | Formal, courteous | Military/professional correspondence |
| R/ | Respectfully | Concise, formal | Established organizational use |
| Respectfully | Respectfully | Formal | Authority or official communication |
| Sincerely | Sincerely | Traditional, professional | Formal business correspondence |
| Best regards | Polite good wishes | Professional, warm | General business email |

| Best | Best regards/wishes | Modern, concise | Everyday professional email |
| Thanks | Appreciation | Friendly | Requests and collaborative emails |
| Take care | Friendly farewell | Personal, warm | Less formal communication |
Key Insight: R/S is not simply another fashionable email abbreviation. It belongs to a more formal communication tradition, so it works best when the recipient understands that convention.

How to Respond When Someone Uses R/S
You usually do not need to acknowledge the abbreviation itself.
Simply respond naturally to the email.
Casual Replies
If you know the sender well:
- “Thanks, received.”
- “Got it, appreciate it.”
- “Perfect, thank you.”
- “Will do.”
Funny Replies
Among colleagues who already joke with each other:
- “I had to look up R/S the first time 😂”
- “You had me decoding email abbreviations.”
- “For a second I thought that was another department.”
- “Very official 😭”
Humor is best kept away from genuinely formal exchanges.
Mature Replies
- “Thank you for the update.”
- “I appreciate your clarification.”
- “The documents have been received.”
- “I’ll review the submission and revert accordingly.”
Respectful Replies
- “Thank you for your assistance.”
- “Respectfully received. I appreciate your guidance.”
- “Thank you. I will proceed as instructed.”
- “I appreciate your time and consideration.”
You do not have to copy R/S just because the sender uses it. Follow your own organization’s communication norms.
Regional & Cultural Usage
Western Culture
R/S is most recognizable in specific formal environments rather than ordinary Western social conversation.
Its documented use is especially associated with U.S. military-style communication, while V/R is also explicitly taught and used within U.S. military correspondence.
Outside those circles, “Best regards” or “Kind regards” is more immediately understandable.
Asian Culture
Across Asian business environments, English email etiquette varies considerably.
Professionals who regularly communicate with U.S. military, defense, government, or multinational organizations may recognize R/S.
Others may not.
For international correspondence, spelling out the closing removes unnecessary ambiguity.
Middle Eastern Culture
Middle Eastern professional communication often places significant value on courteous greetings and respectful language, but that does not mean the specific abbreviation R/S will automatically be familiar.
A recipient may understand “Respectfully submitted” perfectly while wondering what “R/S” stands for.
When communicating internationally, the full phrase or a broadly recognized closing such as “Kind regards” can therefore be clearer.
Global Internet Usage
Unlike LOL, FYI, BTW, or ASAP, R/S has not become universal internet shorthand.
It remains strongly dependent on professional culture.
That distinction matters. Seeing an abbreviation online does not necessarily make it “internet slang.” Some abbreviations migrate into email from specialized workplaces rather than social media.
Gen Z vs Millennials
Age alone is not the best predictor of whether someone understands R/S.
A Gen Z military employee may recognize it instantly, while a Millennial working in advertising may never have encountered it.
Professional background matters more.
Younger workers accustomed to conversational email may also prefer complete, accessible closings such as “Thanks” or “Best.”
The important question is not which generation uses R/S. It is whether the communication culture around the sender and recipient recognizes it.
Is R/S Safe for Kids?
Yes. R/S meaning “Respectfully Submitted” is completely harmless.
There is no inappropriate meaning built into the email sign-off.
A student might even encounter it while reading formal, military, government, or historical correspondence.
The only challenge for younger readers is understanding that abbreviations can have different meanings in different contexts.
Teaching them to look at placement helps. If R/S appears immediately before someone’s name at the bottom of a formal email, “Respectfully Submitted” is a strong interpretation.
Frequently Asked Questions
What does R/S mean in an email?
R/S usually means “Respectfully Submitted” when it appears at the end of an email before the sender’s name.

Is R/S only used by the military?
No, but it is particularly recognizable in military-connected and formal correspondence environments. Other organizations may use it as well.
Should I use R/S in a business email?

Conclusion
So, what does R/S mean in an email?
When those letters appear at the bottom of a message before the sender’s name, the most likely meaning is “Respectfully Submitted.”
It is a compact professional closing rooted in formal correspondence traditions and particularly familiar within military-connected communication.
The important part is context.
R/S,
Michael
is a closing.
But R/S buried inside a technical sentence may mean something completely different.
You should also avoid confusing it with V/R, which means “Very Respectfully.”
Once you understand those distinctions, the abbreviation becomes much less intimidating.
And there is a broader lesson here about professional English. Good communication is not about knowing every abbreviation instantly. Even experienced professionals encounter unfamiliar shorthand when they enter a new company, industry, or culture.
What matters is knowing how to read the clues around it.
Look at where the abbreviation appears, who sent the message, what kind of organization they work in, and what the email is trying to accomplish.
If R/S appears as a formal sign-off, you can now read it confidently for what it is: a concise way of ending a message with respect.
