How to Start
an Email
The first two lines of your email decide whether it gets read or ignored. A complete guide to email opening lines for every situation — professional introductions, follow-ups, cold outreach, job applications, and academic emails. 50+ copy-paste openers, the right greeting for every formality level, and mistakes that make your emails land in the "I'll reply later" pile (they never do).
The Right Greeting for Every Situation
Your greeting sets the tone for the entire email. Match it to your relationship and context — using "Hey" in a job application or "Dear Sir/Madam" to a close colleague both send the wrong signal.
50+ Opening Lines by Situation
Professional First Contact
"I am writing to inquire about [specific topic]."
General business inquiry — clean, direct, universally appropriate.
"My name is [Name], and I am the [Title] at [Company]. I'm reaching out because [reason]."
Cold professional introduction — establishes credibility immediately.
"I was referred to you by [Name/Source] regarding [topic]."
Warm introduction — leverages social proof for higher response rates.
"I recently came across your work on [topic] and wanted to connect."
Networking opener — shows genuine interest without being generic.
Follow-Up Emails
"I wanted to follow up on my previous email regarding [topic]."
Standard follow-up — clear and non-aggressive.
"Thank you for your response. To address your question about [topic]..."
Reply to a reply — immediately advances the conversation.
"Per our conversation on [date], I'm writing to confirm [details]."
Post-meeting follow-up — locks in agreements and next steps.
"I'm circling back on [topic]. Have you had a chance to review [item]?"
Gentle nudge — works well for second or third follow-up without being pushy.
Job Seeking & Applications
"I am writing to express my interest in the [Position] role posted on [Source]."
Standard job application — gets straight to the point.
"With [X years] of experience in [field], I'm excited to apply for [Position] at [Company]."
Shows enthusiasm and immediately qualifies yourself.
"I enjoyed speaking with you at [event]. I'd love to explore opportunities at [Company]."
Post-networking application — personal connection dramatically increases response rates.
"Thank you for taking the time to interview me for [Position]. I wanted to follow up on our conversation."
Post-interview follow-up — always send within 24 hours.
Client & Customer Communication
"Thank you for reaching out. I'd be happy to help with [topic]."
Customer support reply — warm, immediate, solution-oriented.
"I'm writing with an update on [project/order/request]."
Proactive update — clients love being kept informed without asking.
"I wanted to share some exciting news about [product/service/feature]."
Announcement opener — creates positive anticipation.
"I appreciate your patience regarding [issue]. Here's where we stand."
Delay acknowledgment — addresses the elephant in the room directly.
Academic Emails
"I am [Your Name], a student in your [Course Name] class ([Section/Time])."
Professor email — always identify yourself and the class immediately.
"I am writing to request [specific thing] regarding [course/program]."
Academic request — clear purpose from the first sentence.
"I am a [Year] [Major] student interested in your research on [topic]."
Research inquiry — shows you've actually read their work.
"Thank you for your feedback on [assignment]. I have a question about [specific point]."
Following up on grades/feedback — shows engagement, not entitlement.
Cold Outreach & Sales
"I noticed [specific observation about their company/work] and thought [value proposition]."
Research-based opener — shows effort and immediately provides relevance.
"Quick question: are you currently [pain point they likely have]?"
Question-based opener — engages curiosity and qualifies the prospect.
"[Mutual connection] suggested I reach out about [topic]."
Warm referral opener — highest response rate of any cold email technique.
"I help [target audience] [achieve result]. Would a 10-minute call be worth exploring?"
Direct value proposition — no fluff, respects their time.
The Anatomy of a Great Email Opening
Greeting
Match formality to the relationship. 'Dear Dr. Kim,' for professors. 'Hi Sarah,' for colleagues. When unsure, go one level more formal than you think necessary — you can always relax it in the next exchange.
Who You Are (if needed)
If the recipient doesn't know you, state your name, role, and connection in one sentence. Skip this if you've emailed before — they know who you are.
Why You're Writing
State your purpose in the first sentence. 'I'm writing to...' / 'I wanted to ask about...' / 'I'm reaching out because...' — this is the most important line in your entire email.
Context (1-2 sentences max)
Brief background only if necessary to understand the request. Don't over-explain. The reader should know exactly what you need within the first 3 sentences.
7 Opening Line Mistakes That Kill Your Email
Starting with 'I hope this email finds you well'
It's the most overused email opener in existence. It says nothing. Replace with your actual purpose: 'I'm writing to...' or 'I wanted to share...' Save pleasantries for people you genuinely know well.
Using 'To Whom It May Concern'
This signals zero effort. Spend 90 seconds on LinkedIn or the company website to find a real name. If you truly can't: 'Dear [Department] Team,' or 'Dear Hiring Manager,' are far better alternatives.
Starting with an apology
'Sorry to bother you' or 'I apologize for reaching out' immediately positions you as an inconvenience. You have a legitimate reason to email — lead with it confidently. Your message deserves to be read.
Being too vague in the first line
'I wanted to touch base' or 'Just checking in' give the reader zero reason to keep reading. State exactly what you want: 'I'm writing to confirm our meeting time' or 'I have a question about the Q3 report.'
Starting with 'As per my last email'
This is universally read as passive-aggressive, even when you don't intend it. Instead: 'Following up on [specific topic]' or 'To build on our earlier discussion about [topic]' — same meaning, zero hostility.
Writing a paragraph before getting to the point
The first two sentences determine whether your email gets read or skimmed. Don't bury your purpose under backstory. Lead with the ask or key information, then provide context if needed.
Using 'Dear Sir/Madam' for a known recipient
If you know their name and still write 'Dear Sir/Madam,' it feels like a mass email. Always personalize: 'Dear Dr. Patel,' — it takes 3 seconds and makes a lasting first impression.

Frequently Asked Questions
How do I start an email to someone I've never met?
Use 'Dear [Mr./Ms.] [Last Name],' as the greeting. Open with who you are and why you're writing in one sentence: 'My name is [X], and I'm reaching out because [specific reason].' If you were referred, mention that immediately. Skip 'I hope this finds you well' — it wastes their time and yours.
What's the best way to start a professional email?
Greeting + purpose in the first sentence. 'Dear [Name], I am writing to [exact purpose].' That's it. The best professional emails get to the point in under 20 words. The greeting sets formality level (Dear = formal, Hi = casual), and the opening line sets expectations for the entire email.
Is 'Hi' or 'Hello' better for starting a professional email?
'Hello' is slightly more formal and works for any professional context. 'Hi' is warmer and better for colleagues or established contacts. Both are acceptable for most business emails. Avoid 'Hey' in anything client-facing or with someone senior. When in doubt, 'Hello [First Name],' is the safest default.
How do I start a follow-up email without being annoying?
Reference the previous conversation specifically: 'Following up on [topic from last email]' or 'I wanted to check in on the [specific item] we discussed on [date].' Providing new information or value makes follow-ups welcome rather than annoying: 'I have an update on [X]' beats 'Just checking in.'
Should I use the person's first name or last name?
Last name (Dear Mr./Ms. Chen) for first contact, senior people, professors, clients, and formal situations. First name (Hi David) for colleagues, people who've signed their previous email with just their first name, or anyone who has explicitly said 'call me [First Name].' When uncertain, err toward formal — you can always dial it back.
How do I start a cold email that actually gets a response?
Lead with something specific about THEM, not about you. 'I noticed your team recently [achievement/article/launch]' shows you did research. Then connect it to value: 'I think [your solution] could help with [their likely challenge].' Personalized cold emails get 2-3x higher response rates than generic templates.
