Greetings and salutations set the tone for everything that follows. Choose the wrong one and your email reads as stiff, sloppy, or worse, disrespectful before you've made a single real point. The difference between "Dear Mr. Okafor," and "Hey Marcus," isn't just formality. It signals how you see the relationship, how much care you've put into the message, and whether you've matched the context correctly.
What "salutation" actually means
Many writers use "greeting" and "salutation" interchangeably. In strict usage, a salutation is the formal opening line of a letter or email: "Dear Ms. Lindqvist," or "To Whom It May Concern." A greeting is broader and includes spoken or informal written openings like "Good morning" or "Hi there." Both terms appear in style guides without a firm consensus, so don't worry about choosing the right word for the concept. Focus on choosing the right opening for the document.
The salutation sits above the body of a letter and below the recipient's address block. In email, it opens the message body. Either way, it does the same job: it tells the reader the message is for them and sets the register for what follows.
Formal greetings and when to use them
"Dear" remains the standard formal salutation in English business writing. It pairs with a title and surname: "Dear Dr. Chen," or "Dear Professor Nakamura." Use it in first-contact emails to clients, in cover letters, in legal correspondence, and in any situation where you don't yet know the recipient personally.
A few specific cases are worth knowing:
- "Dear Sir or Madam" works when you don't know the recipient's name at all. It's formal but slightly dated. "To Whom It May Concern" is equally acceptable and more common in North American usage.
- "Dear Hiring Manager" is now widely accepted in job application letters when no name is listed in the posting.
- "Dear [First Name]" works in formal emails where you've met the person but the context is still professional. "Dear Sarah," reads warmer than "Dear Ms. Okonkwo," without crossing into casual territory.
Informal greetings and when they fit
Once a working relationship is established, the register usually relaxes. "Hi Marcus," or "Hello Elena," signals familiarity without being unprofessional. Most internal office emails between colleagues run at this level. "Hey" is fine between close colleagues but looks careless in messages to clients or senior leadership.
Skip the salutation entirely only in short, transactional reply chains where the context is obvious and the exchange has already been running for a while. Opening a brand-new email with no greeting at all reads as abrupt in most professional cultures.
How to punctuate greetings correctly
Punctuation trips up a lot of writers. The rule is simple: in American English, a comma follows the salutation in informal contexts ("Hi Priya,") and a colon follows it in formal contexts ("Dear Mr. Okafor:"). British English uses a comma after formal salutations too ("Dear Mr. Okafor,"), which is why you'll see both styles in international correspondence.
Don't mix the two. "Dear Mr. Okafor," (comma) is correct in British and informal American style. "Dear Mr. Okafor:" (colon) is correct in formal American style. Whichever you choose, be consistent throughout the document. Switching from a comma on the salutation to a colon somewhere in the body creates a minor but noticeable inconsistency.
Just as the difference between "its" and "it's" comes down to one character, getting salutation punctuation right comes down to one mark. Small, but visible to a careful reader.
Salutations in group emails
Writing to more than one person? "Dear all," works in formal group emails. "Hi everyone," or "Hi team," fits internal messages. Avoid "Ladies and Gentlemen," outside of very formal ceremonial writing. It reads archaic in most modern business contexts.
If you're addressing two named recipients, list both: "Dear Mr. Fischer and Ms. Reyes," or "Hi Tom and Lena,". More than three names gets unwieldy. At that point, "Dear colleagues," or "Hi all," is cleaner.
Greetings in letters vs. emails
Physical letters hold to stricter conventions than emails. A formal letter always opens with "Dear [Title] [Surname]:" or "Dear [Title] [Surname]," and closes with a matching complimentary close: "Yours sincerely," if you know the recipient's name, "Yours faithfully," if you don't (this is the British standard). American letters typically use "Sincerely," or "Respectfully," regardless.
Email has no universal standard for closings, but "Best regards," "Kind regards," and "Thanks," are the most common in professional contexts. The opening salutation and closing should match in register. A message that opens with "Dear Dr. Mbeki:" and closes with "Cheers," creates a jarring mismatch.
Consistency across your correspondence matters as much as individual choices. Style guides like The Chicago Manual of Style and the AP Stylebook both address salutation conventions, and the two don't always agree. Know which guide your organisation follows and apply it uniformly. That consistency, not the particular choice you make, is what marks confident business writing.
Getting greetings and salutations right is part of the same attention to detail that separates careful writers from careless ones. It's the same discipline that helps writers choose between years, year's, or years' without second-guessing themselves. The rule exists. Learn it once and it stops being a problem.
