How to address someone in a cold email is a one-line decision that gets made before any strategy does, and the verdict is short: “Hi [first name],” for almost everyone, “Dear” plus a surname where region or industry demands it, and never a greeting that guesses. This article is the decision piece for that single line: the default and its exceptions, the executive question, the regional map, and why the salutation is the first spam signal a prospect reads. The lines around it are owned elsewhere: the sentence after the greeting lives in our guide to cold email opening lines, the name that fronts the whole message in our verdict on the cold email sender name, and the block that closes it in cold email signature best practices. This piece is about the two or three words between the subject line and the pitch.
The verdict comes from sending volume, not etiquette theory. Our parent agency, Referral Program Pros, has run more than 4,000 outbound campaigns and booked over 7,000 meetings, and GTM Bud productizes that playbook under a written guarantee: 5 percent positive replies on LinkedIn, 1.5 percent on email, or a full refund. Across those campaigns the greeting was never a line we tried to win with. It was the line we refused to lose with, because a salutation can move a reply rate in only one direction, and that direction is down.
How should you address someone in a cold email?
Address a cold email recipient with “Hi [first name],” and spend the time you saved on the sentence that follows. That is the consensus across the current vendor guidance: Cleverly calls “Hi [first name]” the modern default for professional email, La Growth Machine names “Hi” the strongest cold greeting for B2B outreach, and Woodpecker’s salutations guide argues the greeting needs to fit the recipient, the reason for writing, and the formality the situation calls for rather than impress anyone. The default holds across English-speaking B2B markets, where first names from the first message are the norm. It bends in exactly three situations: regulated and conservative industries where “Dear” still governs, regions where surnames and titles are expected on first contact, and executives inside those formal contexts. The rest of this article maps those exceptions. If none of them applies to your list, the decision is already made, and it took one line.
Here is the thing about that verdict: it is boring on purpose. The greeting is the one part of a cold email where originality is pure risk. “Greetings,” “Good day,” and “Salutations” read as either a translation or a template. A clever greeting promises a clever pitch, and now the body has to cash a check the first word wrote. A plain “Hi [first name],” promises nothing except that a person is writing to a person, which is the only claim a cold email needs its greeting to make.
Why is the greeting a spam signal before anyone reads a word?
The greeting is the first merge field in the message, which makes it the first place automation fails in public. Across our agency’s campaigns, the greeting errors that killed threads were never about formality. They were mechanical, and every one of them announced bulk sending before the pitch got a word in:
- The unfilled placeholder. A literal “Hi [first name],” shipped to a real inbox. Cleverly’s avoid list names the unsent template placeholder explicitly, and it is the most honest spam disclosure a sender can make.
- The empty merge. “Hi ,” with the token silently dropped. The sentence structure survives; the credibility does not.
- The pasted full name. “Hi Sam Reyes,” is a string no human types to another human. It tells the reader the name arrived from a database column, not from knowing them. The one exception is deliberate: “Dear Sam Reyes,” is an accepted gender-neutral formal convention, and the “Dear” is what marks it as a choice rather than a merge accident.
- The scraped casing. “hi sam,” and “Hi SAM,” both say the list was exported, not researched.
- The misspelled name. Cleverly’s list flags this one too, and it is the cruelest failure because effort was spent. One wrong letter in a name converts personalization into evidence against you.
- The generic fallback when a name exists. “To whom it may concern” and “Dear Sir or Madam” in a one-to-one sales email concede that you do not know who you are writing to, which collapses the premise of the entire message.
Notice what is on that list and what is not. No prospect ever deleted a cold email because “Hi” should have been “Hello.” Every item above is a research or pipeline failure wearing a greeting costume, and the fix lives in the data step, not the copy step. The greeting cannot earn a reply, but it is fully capable of ending one before the opening line gets read.
Dear, Hi, or Hello: what does the data actually show?
The only sizable public dataset on greeting words is Boomerang’s analysis of over 300,000 email threads, published on the Boomerang blog. It found “Hey” at a 64.0 percent response rate, “Hello” at 63.6, “Hi” at 62.7, “Greetings” at 57.2, and “Dear” at 56.5, against a 47.5 percent baseline for all messages in the sample. Two honest readings follow. First, every greeting beat no greeting, so the strongest measured effect is simply using one. Second, Boomerang itself attached the caveat that the data came from online communities that skew informal, so it is correspondence data, not cold outreach data. The direction, casual slightly ahead of formal, is worth keeping. The decimals are not worth defending.
That is the entire pinnable evidence base, so the circulating numbers deserve a disposal notice. La Growth Machine’s salutation guides attribute a 27 percent response lift for “Hi” over “Dear” to Yesware and a 53 percent lift for personalized greetings to Boomerang; neither figure appears in any published dataset from the named source that we could find, so we dropped both. Cleverly’s claim that personalization moves reply rates from 3 percent to 7 percent names no study. The claim that “Dear Sir or Madam” cuts engagement by up to 20 percent circulates without a primary source anywhere in the chain. What survives the audit is a consensus, not a statistic: the current guides disagree on decimals and agree on the doctrine, a named first name over a title, and any greeting over none.
The disagreement worth printing is about “Dear” itself. La Growth Machine’s 2026 salutations piece calls “Dear” in email increasingly archaic, while SmartReach’s guide still recommends it as the safest choice for executives, clients, and first-time formal contact, and Reply.io calls formal greetings the best choice in sectors like law and medicine. Both camps are right about their own context, which is the point of the table below: the greeting is decided by the audience, not by the sender’s taste.
How do you address a CEO in a cold email?
Address a CEO in a cold email the same way you would address anyone else in their country and industry: “Hi [first name],” in the United States and most English-speaking markets, and “Dear Mr. [last name]” or “Dear Ms. [last name]” only where regional convention demands it and the title is verifiable. The vendor guidance splits here, and the split is worth reading in full. Instantly’s guide to addressing a CEO recommends Mr. or Ms. plus the last name as the safest default, adjusted for the executive’s location and culture. Cleverly and La Growth Machine treat the first-name greeting as the default at every seniority level. Our campaigns side with the first-name camp for US and UK executives, because a cold email is proposing a conversation between peers, and a greeting that bows before it asks positions you as a vendor before the pitch begins. Formality should follow geography and industry, never job title alone.
The stiffness most senders reach for with executives is a misread of what makes executives hard to reach. A CEO’s inbox problem is volume, not insufficient deference, and “Dear Mr. Chen, I hope this message finds you well” spends the scarcest resource in that inbox, attention, on protocol. What actually changes at the executive tier is everything after the greeting: the research bar, the brevity bar, and the size of the ask. The greeting stays two words. One hard rule survives at every tier: never guess. A guessed “Mr.” aimed at someone who is not one, a guessed “Dr.” the person never uses, or a guessed nickname, “Hi Bob,” for a Robert who signs Robert, each proves in one word that the research the email claims never happened.
Which greeting fits which region and audience?
Formality is a regional setting before it is a personal one. The localized conventions below follow the patterns documented in Babbel’s guide to email greetings and sign-offs in other languages, and the sector rows follow the vendor guidance named above.
| Audience or region | Greeting for a first touch | Verdict |
|---|---|---|
| US, UK, Australia, Netherlands, Nordics | Hi [first name], | The default; first names from message one are the norm |
| Germany, Austria, Switzerland | Sehr geehrter Herr / Sehr geehrte Frau [last name] | Surnames and titles expected on first contact; relax only after they do |
| France and much of Southern Europe | Bonjour Monsieur / Madame [last name], localized | Formal openers first; first names arrive after a reply |
| Japan and South Korea | [last name]-san, or surname plus the local honorific | Formality is non-negotiable on first touch; localize, never translate |
| Law, medicine, government, academia, any region | Dear [first name], or Dear Dr. [last name], | Reply.io calls formal greetings the best choice for these sectors |
| Senior executives in informal markets | Hi [first name], | Seniority does not override the regional default; see the CEO section |
| No verifiable first name | Do not send yet | A missing name is a research failure, not a greeting problem |
Two rules sit under the table. First, localize the convention, not your greeting: a word-for-word translation of “Hi Sam” into German or Japanese lands as wrong as “Sehr geehrter” would in Austin. Second, when a prospect replies, their register becomes the register. A German director who answers “Hallo Thomas” has closed the formality gap personally, and staying stiff after that reads as not listening, which is a worse signal in outreach than any greeting choice.
What do you do when you cannot find the name?
You fix the list, not the greeting. Woodpecker rules “To whom it may concern” a last resort and suggests role-based fallbacks like “Dear Hiring Manager” when no name can be found, and Valley’s salutations guide likewise keeps generic and role-based openers as the bottom rung of its situational table. That guidance is right for its context, job applications and support inboxes, and wrong for prospecting. In cold outreach the name is not decoration on the message; it is the minimum proof the message was aimed. A prospect you cannot name is a prospect you have not researched, and no fallback phrasing converts an unaimed email into an aimed one.
This is also where the scale excuse dies. The traditional defense of greeting shortcuts was volume: nobody can verify a thousand names, casings, and regional registers by hand. That is now a solved research problem rather than a copy problem. An AI cold email writer that researches each prospect before writing resolves the name, the spelling, the title, and the register from the same sources it pulls the opening line from, which is exactly how GTM Bud ships campaigns where the greeting errors in the list above structurally cannot occur. If a tool cannot tell you the recipient’s verified first name, it has no business sending them anything yet.
Frequently asked questions about cold email greetings
Is “Hey” too casual for a cold email?
Yes, for a stranger. Boomerang’s analysis of over 300,000 threads found “Hey” earned the highest reply rate of any opening at 64 percent, but that data came from informal online communities, not cold outreach, a caveat Boomerang itself attached. Shopify’s greetings guide draws the cold-specific line: lean formal with strangers, and never open cold outreach with “hey.” “Hi” buys nearly the same warmth with none of the presumption.
Should you use Mr. or Ms. in a cold email?
Only when the region or industry expects it, and only when you can verify both the surname and how the person refers to themselves. A guessed honorific is the one greeting error worse than a generic one, because a misgendered “Mr.” proves carelessness about the exact person you claim to have researched. When the norm calls for formality but the title cannot be verified, “Dear” plus the full name sidesteps the guess and is an accepted gender-neutral convention.
How do you address two people in the same cold email?
You do not. A cold email with two names in the greeting is a meeting request addressed to a committee, and committees do not reply; the message also cannot be personal to either reader. Send each stakeholder their own message with their own greeting and their own reason for receiving it. A cold email automation tool that researches per prospect makes that split the default rather than extra work, and the threads can reference each other once one person answers.
Do you put a comma or a colon after a cold email greeting?
A comma. SmartReach’s salutation guide maps the punctuation to register, a comma for casual greetings and a colon for formal ones, and a cold email is deliberately written in the register of a short personal note. “Hi [first name]:” makes a two-sentence favor ask read like a legal memo. Save the colon for cover letters.
How do you address someone with a doctorate or other credential?
Use the credential when it is verifiable and the person uses it themselves: “Hi Dr. [last name],” for a physician or professor who signs that way. In fields where the title is part of professional identity, medicine and academia especially, dropping it costs more than the formality does. Everywhere else the first-name default holds, because a title the person never uses reads like a scraped data field rather than research.
Get the greeting right once, then let it disappear
How to address someone in a cold email is a trade-off with a lopsided payoff: the perfect greeting earns you nothing a competent one would not, and a wrong one, guessed, misspelled, unmerged, or tone-deaf to region, ends the message at word two. So spend the decision once. “Hi [first name],” as the default, “Dear” with a verified surname where the region or the sector demands it, localized conventions abroad, no guesses anywhere, and no send at all when the name is missing. Then move your attention to the lines that can actually win the reply.
GTM Bud makes that discipline the path of least resistance. Its cold email automation tool verifies each prospect’s name and context during research, before a single line is written, and it carries the same written guarantee our agency’s 7,000+ booked meetings stand behind: 5 percent positive replies on LinkedIn, 1.5 percent on email, or a full refund. The greeting should be the least interesting line in your email. Make it boring, make it right, and let the pitch do the talking.
