Quick Takeaways
- For 2 to 5 recipients, greet everyone by name. For 6 or more, switch to a group greeting like “Hi team.”
- List names by seniority first, then external contacts before internal ones, then alphabetical order as a tiebreaker.
- Use “To” for people who need to act, “CC” for visibility only, and “BCC” to protect a long list of addresses.
- A greeting still beats no greeting: emails that open with “Hi” or “Hey” get roughly a third more replies than ones that skip a greeting entirely.
- Never paste a long external list into “To” or “CC.” Use BCC or send individually.
What addressing multiple recipients actually means
Addressing an email to multiple recipients means naming or greeting more than one person in the opening line, and deciding where each address goes: To, CC, or BCC. Get the greeting wrong and you sound like a mail merge. Get the fields wrong and you expose people’s addresses or bury the one person who actually needs to respond.
Most guides treat these as two separate problems. They’re one problem. Who you name and where you put them both signal the same thing: who this email is actually for.
How to greet 2 to 5 recipients by name
Small groups deserve names. It takes five extra seconds and it shows you know exactly who’s reading.
Semi-formal: “Hi Sarah, Mike, and Priya,” Formal: “Dear Mr. Smith and Dr. Jones:” Casual: “Hey team,”
Semi-formal covers the bulk of day-to-day work email. Save the formal version for first contact with a client, a board member, or anyone whose title you’d use if you shook their hand.
An analysis of over 300,000 emails found that messages opening with “Hi” (63% reply rate) and “Hey” (64%) performed almost identically, and both beat emails with no greeting at all by about a third. The greeting itself isn’t decorative. Skipping it costs you replies.
Name order and seniority rules
Three rules, applied in order:
- Seniority first. If the VP is on the thread, their name leads.
- External before internal. Emailing a client alongside your own team? The client’s name comes first.
- Alphabetical as the tiebreaker. Once rank and internal/external status are equal, alphabetize.
“Dear Dr. Patel, Mr. Reyes, and Ms. Tanaka,” respects both the hierarchy and the reader. Skipping straight to first names for a senior external contact you’ve never met can read as careless.
How to greet 6 or more recipients
Past five names, listing everyone gets clumsy. Nobody wants a greeting longer than the message itself.
“Hi team,” works as a default for internal groups. “Dear [Department] Team,” steps up the formality for leadership or a specific unit. “Dear all,” suits company-wide updates but reads slightly weak for external recipients, where “Dear partners” or naming the company directly lands better.
If you don’t know every name, a role-based greeting solves it: “Dear hiring committee,” or “Dear procurement team,” is specific enough to feel intentional without pretending you know people you don’t.
Choosing between “Hi,” “Hello,” and “Dear”
Match the register to the relationship, then keep it consistent across the whole greeting. Opening with “Dear Mr. Chen” and then addressing his colleague as “Hey Lisa” in the same line reads as an oversight, not a style choice.
Use “Dear” for formal first contact: new clients, executives, anyone outside your usual circle. Use “Hi” for internal threads and ongoing conversations. In a reply chain, you generally only need the greeting on your first message. After that, it reads like a normal conversation.
To vs CC vs BCC: where each recipient belongs
Greeting etiquette only solves half the problem. Field placement solves the other half, and it’s the part people get wrong more often. As one 2026 etiquette breakdown puts it, the basic split still holds even as tools change: To is for action, CC is for visibility, BCC is for discretion.
Quick Comparison
| Field | Best For | Key Benefit | Limitation |
| To | People who must act or reply | Signals clear ownership | Everyone in To/CC sees these addresses |
| CC | People who need visibility, no action required | Keeps stakeholders informed | Adds inbox volume if overused |
| BCC | Large or external lists | Protects recipient privacy | Hides participation, which can read as secretive if misused |
To achieve correct field placement: 1. Put people who need to respond in To. 2. Put people who need visibility only in CC. 3. Put large or unrelated-to-each-other lists in BCC.
A B2B etiquette analysis covering 2.4 million tracked messages found that 78% of professionals use CC daily, but only 22% apply it correctly by standard benchmarks. The cost isn’t trivial: a separate workplace inbox survey put the average employee’s unnecessary CC volume at 47 messages a week.
What most guides skip is that BCC has a real failure mode. If someone you BCC’d hits “Reply All,” their inclusion becomes visible to everyone, which can look like you were hiding something even when the reason was legitimate. Emily Post’s etiquette guidance recommends avoiding long address lists in To or CC altogether and using BCC, or sending individually, once a list gets long. When you do BCC a group, put your own address in To. Some mail clients require one, and it keeps the header clean. Then say in the body who else received it, so nobody wonders if the email was misdirected.
I’ve seen conflicting advice on where the line sits between CC and BCC for internal announcements. Some etiquette guides say CC is always more transparent and should be the default. My read: for internal teams who already know each other, CC is fine and often better since it lets people see who’s aware of what. BCC earns its place once the list includes people who don’t know each other or shouldn’t see each other’s addresses.
Common mistakes to avoid
- Pasting a long list into To. Every recipient sees every address. Use BCC once the list is external or unfamiliar to itself.
- Reply All without checking. Before hitting it, ask whether everyone on the thread actually needs your response.
- Vague subject lines. “Update” tells nobody anything. “Q3 budget approval, need input by Friday” tells everyone what to do.
- No named owner. If five people are CC’d and nobody’s told who’s responsible, nothing happens. Naming a person directly in the body fixes this.
- Mixed formality in one greeting. Pick a register for the whole line and hold it.
Voice search questions, answered
What’s the best way to greet a group email? Name everyone if there are 5 or fewer recipients. Switch to a collective greeting like “Hi team” once you pass that number.
How do I address an email if I don’t know everyone’s name? Use a role-based greeting such as “Dear hiring manager” or “Dear support team” instead of a generic line like “To whom it may concern.”
Should I use CC or BCC for a large recipient list? Use BCC once the list is external, unfamiliar to each other, or long enough that exposing every address becomes a privacy problem.
When should I put someone in CC instead of To? Put them in CC when they only need visibility and aren’t expected to respond or act.
Is “Dear all” appropriate for external emails? It works for internal, cross-functional updates. For external recipients, naming the group specifically, such as “Dear [Company] team,” reads more polished.
This guide covers greetings and recipient fields for standard business email. It doesn’t cover mail merge tools, mass-marketing platforms, or GDPR requirements for bulk sends, which follow separate rules.
