What are professional email greetings?

Four words sit at the top of almost every business email you will ever send. Dear, Hello, Hi, or Good morning. That tiny line shapes how the reader feels about everything that follows. Pick the wrong one and a careful message can feel too cold or too casual before the reader reaches sentence two.

Professional email greetings are the salutations you use to address the reader at the start of a business message. They range from formal (Dear Ms. Lopez) to conversational (Hi Tom). The right choice depends on your relationship with the reader, the purpose of the message, and the norms of your industry. Here is a practical guide to professional email greetings.

What counts as a professional email greeting?

A professional greeting addresses the reader directly and sets a respectful tone. It does not use slang, nicknames the reader has not invited, or overly familiar language with new contacts. Even a casual "Hi" is professional when paired with a clear message and a branded sender address.

The greeting sits on its own line, followed by a blank line before the body begins. This small formatting choice makes your email easier to read, consistent with the standards in email etiquette rules for brands.

Common professional email greetings and when to use them

Different greetings signal different levels of formality. Choose based on the situation, not habit.

1. Dear [Name]

Use Dear for formal messages, first contact with senior contacts, official requests, and cover letters. "Dear Mr. Alvarez" or "Dear Dr. Kim" shows respect. It pairs well with the structure described in how to start a formal email.

2. Hello [Name]

Hello works in most business contexts. It is polite without being stiff. Use it with clients, partners, and colleagues when you want a balanced tone that is neither too formal nor too casual.

3. Hi [Name]

Hi is the most common greeting in everyday business email. It fits established relationships, internal teams, and industries with a relaxed communication style. Pair it with a professional body and sign-off so the overall message stays polished.

4. Good morning or Good afternoon

Time-based greetings work when you know the reader's time zone and the message is not delayed. They add a personal touch to client check-ins and team updates. Avoid them in formal or time-sensitive official correspondence where the send time might not match the reader's day.

5. Greetings for groups

When addressing multiple people, use Hi everyone, Hello team, or Dear colleagues. If one person is the primary recipient, name them in the greeting and mention the group. "Hi Sarah, copying the project team for visibility" keeps the focus clear.

Greetings to avoid in professional email

Skip Hey, Hiya, Yo, and similar casual openers with external contacts. Avoid "To Whom It May Concern" when a specific name is available on the company website or in the thread. Do not use emoji in place of a greeting.

If you are unsure, lean slightly more formal for a first message and adjust based on how the reader replies. Their greeting in the response tells you what tone they prefer. Combine good greetings with guidance from how to start a business email and a credible address from what is a custom email domain for a strong first impression.
