How to Start an Email: The Complete Guide

Why Email Openings Matter

Your email greeting and opening line are the first impression in written communication. Research shows that emails with personalized, clear openings receive 26% higher response rates than those with generic or no greetings. The opening signals professionalism, respect, and intent — all within the first few seconds of reading.

Best Email Greetings

Professional Greetings

• Dear [Name] — The gold standard for formal communication. Best for first emails, client correspondence, and authority figures.
• Hello [Name] — Professional yet approachable. Works for most business situations in 2026.
• Hi [Name] — The most common professional greeting today. Friendly without being too casual.
• Good morning/afternoon [Name] — Adds a personal touch. Be mindful of time zones.

For professional email openings, "Hi [Name]" or "Hello [Name]" are the safest choices for most business contexts. Reserve "Dear" for formal situations.

Academic Greetings

Emailing professors and teachers requires extra formality. See our guides on starting emails to a professor and to a teacher.

• Dear Professor [Last Name] — Always use their title. Never first name unless they specifically invite it.
• Dear Dr. [Last Name] — If they have a doctorate, use "Dr." unless they prefer "Professor."
• Dear Mr./Ms. [Last Name] — For teachers without a doctorate title.

Group Email Greetings

Addressing multiple recipients requires different approaches. See our guide on starting emails to multiple people.

• Hi everyone — Friendly and inclusive for teams.
• Hi team — Good for department or project teams.
• Dear all — More formal group greeting.
• Hi [Name], [Name], and [Name] — Personal touch for small groups (2-4 people).

Cold Outreach Greetings

For emailing companies or people you have never met:

• Hi [Name] — If you know their name, use it. Personal is always better.
• Hello — If you do not know the recipient's name.
• Dear [Title/Team] — "Dear Hiring Manager" or "Dear Customer Service Team" when you lack a name.

Best Opening Lines After Your Greeting

Establishing Context

• "I am writing to inquire about [topic]."
• "Following up on our conversation from [date/event]."
• "[Mutual connection] suggested I reach out to you about [topic]."
• "I came across your [article/talk/work] and wanted to discuss [topic]."

Making a Request

• "I am reaching out to ask about [specific request]."
• "I would appreciate your help with [specific topic]."
• "I am hoping you might be able to [specific action]."

Sharing Information

• "I wanted to share an update on [project/topic]."
• "Here is the [document/information] you requested."
• "I thought you might find this [resource/insight] useful."

Greetings to Avoid

• "To Whom It May Concern" — Outdated and impersonal. Find the person's name if possible.
• "Hey" — Too casual for professional email. Save it for friends.
• No greeting at all — Starting with your message directly feels abrupt and rude.
• "Dear Sir/Madam" — Outdated and assumes gender. Use a gender-neutral alternative.
• Misspelling their name — Double-check before sending. Nothing sinks credibility faster.

Opening Lines to Avoid

• "I hope this email finds you well" — So overused it has become meaningless. Use something more specific.
• "Sorry to bother you" — Undermines your message before it starts. If you are writing, your message has value.
• "Just checking in" — Vague. State your purpose directly.
• "As per my previous email" — Passive-aggressive. See polite follow-up approaches instead.
