N.B. in email: meaning and clear use
What is the difference between N.B. and P.S. in an email?
N.B. stands for the Latin words nota bene, which mean note well. In English correspondence, writers place it before an extra detail that requires attention. It does not replace the main message, but it highlights a condition, reminder, or helpful update that belongs with that message.
Key points
- N.B. tells your reader to pay close attention to an extra point.
- Keep your primary instructions in the main body text, and save N.B. for secondary details or conditions.
- When clarity is your top priority in an everyday email, choose the word Note or write a complete direct sentence.

-
The training session starts promptly at nine o'clock. N.B.: Please bring a photo ID.
The note adds a practical requirement without cluttering the first sentence about timing.
-
All expense claims must arrive by Friday. N.B.: Original paper receipts are no longer required.
The note clarifies an exception to the routine filing process.
Read the full guide
Decide whether your detail belongs in a note
Put the main action where the reader can easily find it. A note can draw attention to a reminder, exception, or requirement, but essential information should not be hidden at the end of a long message. In a short message, an N.B. reminder can follow the main detail clearly.
-
Please submit your project proposal by noon. N.B.: Digital signatures are acceptable.
Why it works: The core deadline remains in the main sentence, while the note adds an acceptable format option.
Your turn
Where should you place a mandatory deadline that every team member must meet?
Answer: In the opening sentence of the main message

Answer: In the opening sentence of the main message
Essential deadlines need immediate visibility in the primary text so readers do not overlook them.
Identify the meaning of nota bene
The abbreviation N.B. comes from the Latin phrase nota bene, which translates into English as note well or pay attention. English speakers borrowed this phrase centuries ago for formal academic texts, legal publications, and official correspondence. Today it still signals that the following sentence contains a point worth careful observation.
-
N.B.: The building entrance on Elm Street closes after six in the evening.
Why it works: Here the Latin abbreviation serves as a formal reminder about building access hours.
You can practise this again in Business English phrases: clear workplace communication and Transferring a ticket.
Your turn
What does the Latin root phrase nota bene mean in plain English?
Answer: Note well or pay attention
Show the answer
Answer: Note well or pay attention
Nota bene directly translates to note well, directing the reader to observe a specific detail.
Choose between N.B. and the plain word Note
Modern workplaces value speed and direct communication. While N.B. is recognized in formal writing, some colleagues or international partners might pause over the abbreviation. Using the simple word Note offers identical meaning while keeping the tone clear and accessible for people from diverse language backgrounds.
-
Note: The regional office will observe a holiday on Monday.
Why it works: The plain English word provides clarity without sounding overly formal or academic.
Your turn
Why do many business writers choose Note instead of N.B. in daily emails?
Answer: Note is instantly clear to international readers
Show the answer
Answer: Note is instantly clear to international readers
The plain word Note avoids Latin abbreviations and is immediately clear across global teams.
Position the note after the primary instructions
Place a note near the information it explains so the reader can connect the two. In an email, keep the main request clear in the subject line and body. Use the note for a related detail rather than making the reader search for the action you need.
-
We have booked the main auditorium for the conference. N.B.: Microphones will be provided on stage.
Why it works: The note follows the room booking confirmation and adds a secondary equipment fact.
Your turn
Where does an N.B. note function most effectively in an email?
Answer: Right after the sentence or paragraph it supports
Show the answer
Answer: Right after the sentence or paragraph it supports
Placing the note directly after the relevant message gives the recipient proper context.
Select periods or plain capitals consistently
You will see this abbreviation written with periods as N.B. and without periods as NB. Both styles are acceptable across professional publications. American usage often retains the periods, whereas British style guides frequently omit them. Whichever pattern you select, maintain that exact punctuation throughout your document.
-
NB: Please keep a copy of your application receipt.
Why it works: This example omits periods, which is common in modern British business style.
Your turn
What is the most important punctuation rule when writing N.B. or NB?
Answer: Keep the chosen style consistent throughout the message
Show the answer
Answer: Keep the chosen style consistent throughout the message
Either N.B. or NB is acceptable, but mixing both styles in one document looks careless.
Separate urgent requirements from secondary notes
A common writing mistake is using N.B. to emphasize an urgent instruction that the reader must execute immediately. If a recipient must approve a contract, send funds, or confirm attendance, write that requirement as a direct command. An extra note should support the request rather than deliver the main command.
-
Send your travel dates today so we can purchase the flight. N.B.: Airline seat choices are limited.
Why it works: The mandatory action sits in the first sentence, while the note adds background advice.
Your turn
What type of information is poorly suited for an N.B. label?
Answer: The primary action that the reader must take today
Show the answer
Answer: The primary action that the reader must take today
Primary action requests belong in the main text where the reader can immediately spot them.
Pronounce the abbreviation letters aloud
When native speakers read N.B. aloud in a presentation or meeting, they pronounce each letter name individually as en bee. They never attempt to pronounce the abbreviation as a single word. In casual conversation, most people simply speak the English words please note or keep in mind instead.
-
The speaker pointed to the slide and said, 'Please note, the museum closes early on Sundays.'
Why it works: In spoken speech, saying please note sounds more natural than reading the letters en bee.
Your turn
How do English speakers pronounce the abbreviation N.B. when reading it aloud?
Answer: As two individual letter sounds: en bee
Show the answer
Answer: As two individual letter sounds: en bee
N.B. is pronounced letter by letter as en bee, rather than blended into a single word.
Match your note format to your reader
Consider who will read your words before finalizing an email. An internal message to an office peer calls for informal clarity, making Note or a standard sentence ideal. In contrast, formal announcements, university course syllabi, and legal dispatches welcome N.B. because it matches traditional document standards.
-
N.B.: Course registration closes twenty-four hours before the opening lecture.
Why it works: A university syllabus is a formal setting where N.B. fits standard academic style.
Your turn
Which document represents a suitable context for using N.B.?
Answer: A formal academic syllabus or policy guideline
Show the answer
Answer: A formal academic syllabus or policy guideline
Formal academic syllabi and organizational policy documents match the formal tone of N.B.
Use it naturally
How people really use “N.B.”
Formal Fits reports, emails to clients and speeches.
Words it often goes with
- add N.B.You can add N.B. before an extra detail in a formal message.
- use N.B.Some writers use N.B. to introduce a special note.
- N.B. in an emailYou might see N.B. in an email about a formal agreement.
What people also say
- “Note: Please bring a photo ID.” instead of “N.B.: Please bring a photo ID.” Note is a clearer label for a routine workplace email.
- “Please bring a photo ID.” instead of “N.B.: Please bring a photo ID.” A direct sentence makes the request easy to understand.
Questions about "N.B. in email: meaning and clear use"
What is the difference between N.B. and P.S. in an email?
P.S. stands for postscript, which represents an afterthought added after signing a letter. In contrast, N.B. stands for nota bene and calls attention to a significant detail, rule, or qualification related directly to the primary topic. You use N.B. when the information matters to the main subject, whereas P.S. often introduces an unrelated personal note or casual remark.
N.B.: The building alarm activates at eight o'clock.
P.S.: Say hello to David for me.
Should I write N.B. with periods or plain NB without them?
Both forms are acceptable in modern English correspondence. American style guides often recommend writing periods after each letter as N.B., whereas British publications and casual corporate writing frequently omit the dots and write NB. You should check whether your workplace style handbook has a preference, and maintain the same format throughout your document.
N.B.: Please bring your laptop charger to the training session.
NB: Conference badges are required for entry.
Can I put N.B. inside an email subject line?
A clear subject line usually works better than N.B. because it tells the reader what the email is about. Put the topic or required action there, then add any note in the body. Readers who do not know the abbreviation can then understand the message without looking it up.
Updated Schedule: Marketing workshop moves to Room 302.
How should I pronounce N.B. when speaking with colleagues?
If you read the written abbreviation out loud, pronounce the individual letters as en bee. However, native English speakers rarely say those letters during conversational speech. In spoken conversations, people typically say please note, remember that, or keep in mind instead of pronouncing the abbreviation.
Please note that our flight leaves thirty minutes earlier than scheduled.
Before you go
Remember this
N.B. tells your reader to pay close attention to an extra point. Keep your primary instructions in the main body text, and save N.B. for secondary details or conditions. When clarity is your top priority in an everyday email, choose the word Note or write a complete direct sentence.

Speak
Say it with the speaker, then use it in your own answer.
Shadow
Say it along with the speaker
Play the line slowly, then speak at the same time as the speaker. Copy the rhythm, not just the words.
Your turn
Say it your way
Speak for 30 to 60 seconds from memory. Imagine your museum ticket has an extra detail marked N.B. Tell a friend what the ticket says, explain the label, and suggest how the museum could make that detail clearer for visitors.
Use: N.B. Note
Take ten seconds to think, then answer out loud without looking at the lesson. Speak for the time shown in the task above. Nothing is sent unless you ask for feedback.

Hear how someone else might say it
Our museum ticket says we can enter at ten on Saturday. Below that, it says, “N.B.: The cafe is closed this weekend.” N.B. means note well. It draws our attention to an extra detail. We can still visit the museum, but we should eat before we go or find lunch nearby. I think the museum could use “Note” because more visitors would understand it right away. I would put that sentence below the opening hours. Then we could see it easily while planning our visit.
Try once more and answer this: What does the extra detail tell us to do?
