A professional email salutation is the first direct contact you make with your reader. Before they've processed a single argument, request, or piece of news, they've already reacted to how you opened. That reaction shapes everything that follows. Yet most writers spend far less time on the salutation than they do on any other part of the message.
What a salutation actually does
The salutation in a professional email signals three things at once: how well you know the recipient, what level of formality you're operating at, and whether you've done the basic work of identifying who you're talking to. A salutation that gets any of those three wrong creates friction before the content has a chance to land.
It's different from a greeting in a letter. Email moves faster, the context changes more often, and the norms have shifted considerably over the past decade. What read as appropriately formal in 2010 can read as stiff or even dismissive now.
The most common salutation types and when to use them
"Dear [Name]" remains the safest choice for formal professional contexts: a first message to a senior executive, a legal or financial communication, or any situation where you don't know the person at all. It's never wrong, but it can feel heavy in a fast-moving email thread between colleagues.
"Hi [Name]" is the workhorse of modern professional email. It's warm without being informal, direct without being cold. Most internal messages, client updates, and professional introductions work well with this opener. If you're ever uncertain which way to lean, "Hi [Name]" is the reliable middle ground.
"Hello [Name]" sits just a touch more formal than "Hi" and slightly less formal than "Dear." It works well when you want a measured, composed tone, for instance in a first reply to a new business contact or a message to someone you've met once but don't know well.
"Good morning" or "Good afternoon" add a small warmth that some readers appreciate. The risk is time zones: if your reader is three hours behind you and reads the message after lunch, a "Good morning" can feel slightly off. Use these when you know the recipient's location and the message is time-sensitive to that day.
Using the person's name correctly
Whatever salutation you choose, use the name the person actually goes by, not the formal name on their email signature unless that's how they introduced themselves. If their signature says "Jonathan" but they signed their last email "Jon," use Jon. Defaulting to the longer formal version when someone has given you a shorter one reads as indifference.
Spelling matters more here than in almost any other part of the email. A misspelled name in the salutation signals that you haven't paid attention, and that signal arrives before anything else. Double-check every time, especially for names that have multiple common spellings: Sarah vs Sara, Catherine vs Katherine, Michael vs Michel.
On the question of titles: if you're writing to a doctor, professor, or someone with a formal title and you don't know their preference, use the title in the first email. Let them set the tone in their reply. If they sign off as "Dr. Patel" in their response, match that. If they sign off as "Priya," you have your answer. For a deeper look at how titles work in professional address, the guide on when to use Miss, Mrs, Ms, and Mx covers the logic behind each form and when to apply them.
When you don't know who you're writing to
This is where writers reach for "To Whom It May Concern" or "Dear Sir or Madam," and both choices carry baggage. They signal that you either couldn't be bothered to find out who the right recipient is, or that the message is so generic it could go to anyone. Neither impression serves you.
A better approach: spend two minutes finding a name. LinkedIn, the company website, and the email thread you're replying to are almost always enough. If you genuinely can't find a specific person, address the role instead: "Dear Hiring Manager" or "Dear Customer Service Team." These are more targeted than a catch-all phrase and don't raise the same questions. The case against legacy phrases like these is made clearly in the piece on alternatives to "Dear Sir or Madam", which is worth reading before you default to habit.
Group salutations: addressing more than one person
When an email goes to two or three named people, list them by name: "Hi Priya, Tom, and Lena." It takes three seconds and tells each recipient that they're expected to read and respond, not just be looped in for information.
For larger groups, "Hi everyone," "Hi all," or "Hi team" are clean options. "Dear all" reads slightly dated. "To all," without a greeting verb, reads like a memo and lacks warmth. Avoid listing more than four names in a salutation; at that point, "Hi team" or "Hi everyone" becomes the cleaner choice.
If you're writing a single message that's going to different people in different contexts, a salutation addressed to one person may confuse the others. Reconsider whether the message should be split into separate emails before you settle on a group opener.
Salutation punctuation
In American English, a comma after the salutation is standard in informal email ("Hi Priya,"), and a colon is used in very formal correspondence ("Dear Dr. Okafor:"). In British English, the colon is rarely used in email; a comma or no punctuation at all is more common. Whatever you choose, be consistent within an organisation. Mixing punctuation styles across a team's external communications looks careless.
One thing that never varies: leave a blank line between the salutation and the first sentence of the body. Running them together makes the email harder to skim and harder to read.
What not to do
Avoid "Hey" in professional email unless you have a genuinely informal relationship with the recipient and are confident they'd use the same word with you. It's not universally offensive, but it's easy to misjudge, and the downside risk is higher than the upside.
Don't skip the salutation entirely in a new message thread. Opening with a bare name ("Priya,") or diving straight into the body feels abrupt. In a fast back-and-forth thread, dropping the salutation after the first exchange is fine. In a new email, it signals that you're in a hurry and that the reader should feel the pressure of that.
Don't use "Greetings" as a standalone opener. It's the salutation equivalent of a form letter and reads as impersonal regardless of what follows. The same goes for "Hello there," which adds a word without adding warmth.
The salutation is a small piece of an email, but it carries disproportionate weight. A reader who feels addressed correctly arrives at your first sentence in a better state than one who felt misidentified or ignored. Getting it right is a matter of two seconds of thought. That's a good return on the investment.
