We all send and receive dozens of emails every day. Some get immediate responses, some disappear into inboxes never to be seen again. The difference often comes down to how the email is written.
In our guide for how to type an email you'll learn what every professional email needs and how to write each part of it.
How to write an email, step-by-step
Whether you're emailing a new client or following up with a colleague, the structure of your message matters more than most people realize. The average professional receives 29 emails a day that need a response, according to the Fyxer Admin Burden Index, 2026, a survey of 5,000 UK and US office workers. A well-written email is clear, considerate of the reader's time, and easy to act on. These seven steps will get you there:
Write a specific, descriptive subject line
Open with the right greeting for your relationship
State your reason for writing in the first sentence
Fyxer organizes your inbox and drafts replies in your voice so you can focus on the conversations that need your attention
Your subject line is the first thing the reader will see. It determines whether they'll open your email immediately, save it for later, or… ignore it entirely. A good subject line tells the reader exactly what your email is about in 5 to 8 words.
Make your subject line specific and descriptive. For example, instead of writing "Question," write "Question About Q4 Budget Approval." Instead of "Meeting," write "Meeting Request: Project Kickoff Next Tuesday."
The more specific you are, the easier you make it for the recipient to prioritize your email.
If your email involves a deadline, project name, or specific request, put that information in the subject line:
"Invoice #03 due February 15"
"Feedback needed by Friday: Marketing proposal"
"Action required: Approve expense report"
According to research from Harvard Business Review, clear and specific subject lines significantly increase response rates. Avoid vague or misleading subject lines. Phrases like "Important," "Hi," or "Read This" don't tell the recipient anything useful.
Step 2: Use a professional greeting
How you start your email sets the tone for everything that follows.
For professional contacts you don't know well, use "Dear [Name]" or "Hello [Name]." For colleagues you work with regularly, "Hi [Name]" is completely fine and creates a friendly, approachable tone.
If you're emailing someone for the first time, opt to sound more formal. Your emails can always become more casual as you get to know each other. Avoid the dreaded "To Whom It May Concern" at all costs. It’s impersonal and, well, unnecessary.
Your first sentence needs to tell the reader why you're writing. This isn’t a murder mystery novel and there’s no need to bury the lead. Get straight to the point.
Here are three examples of strong opening sentences:
"I'm writing to request approval for the new hire in our department."
"I wanted to follow up on our conversation about the website redesign."
"I'm reaching out to ask if you're available for a meeting next week."
Step 4: Organize your email into paragraphs
The body of your email should be easy to read. This means breaking your information into short paragraphs. You can use bold formatting to highlight key points, but be mindful that large volumes of bold text could be interpreted as unnecessarily aggressive.
Keep paragraphs short. Three to four sentences is ideal. Long blocks of text make your email harder to scan and you risk losing the reader to another task.
According to Forbes, it’s important to make sure your email contains white space for ease of reading, especially on a cell phone. To increase white space, feel free to break up paragraphs by using numbered lists or bullet points. These are particularly helpful when you're explaining a process or giving instructions.
Step 5: Include a clear call to action
Some emails are just an update, others require the reader to take action. Your call to action tells the reader exactly what you need from them.
Make your requests specific. Instead of "Let me know your thoughts," write "Please review the attached proposal and let me know if you approve the budget by Friday."
When you need something by a set date, say so clearly. Place your call to action near the end of your email, after you've provided all necessary context, so that it’s the final thing that sticks in their mind.
Step 6: Close with an appropriate sign-off
How you end your email matters as much as how you begin it. Your closing should match the tone of your message and your relationship with the recipient.
Common professional closings include:
Best regards
Sincerely
Thank you
Best
For colleagues you work with regularly, you can use more casual closings like "Thanks" or "Cheers".
Always include a signature with your full name and relevant contact information: your job title, company name, phone number, and email address. A complete signature makes it easy for recipients to contact you through other channels if needed.
Proofreading is fundamental. Even the best-written email loses credibility if it contains obvious errors. Always proofread your message before hitting send.
Read your email out loud. This helps you catch awkward phrasing, run-on sentences, and missing words. Check for common mistakes:
Misspelled names
Missing attachments
Incorrect information (dates, times, numbers)
Unclear pronouns
Use spell check, but don't rely on it completely. For important emails, consider waiting a few minutes, making a coffee, and coming back to read it one more time before sending.
How to write an email for different situations
There's no single right way to write a professional email. The approach that works for a client pitch won't work for an internal update, and vice versa. Here's how to adjust based on context.
Formal emails
Use these when you're writing to someone senior, someone you haven't met, or in a context where getting the tone wrong could have real consequences. Think client introductions, emails to executives, job applications, or anything legal or financial.
Keep it structured. Lead with a clear reason for writing, stay factual, and avoid contractions if the relationship calls for it. "I am writing to request" rather than "I'm writing to request." Close with "Best regards" or "Sincerely" and include your full signature.
Emails to someone you don't know
The first email sets the tone for the entire relationship, so get it right. Introduce yourself briefly in the first sentence, explain why you're reaching out, and make it easy for them to respond. Keep it short. People are more likely to reply to a concise message than a detailed one they don't have time to process.
Avoid "To Whom It May Concern." Find a name if you can. If you genuinely can't, "Hello" works better than a formal opener that signals you didn't try.
Follow-up emails
If you haven't heard back, it's fine to follow up once. Keep it brief and assume good intent. Something like: "Just following up on my email from last week. Happy to answer any questions if that would help." Don't apologize for following up, and don't add pressure. One clear, friendly nudge is usually enough.
For anyone managing a high volume of outbound conversations, staying on top of follow-ups is where deals either progress or stall.
If you use an AI email assistant, follow-up drafts are often ready for you to review before you've even thought to check. That kind of prompt makes it easier to stay on top of conversations without letting things slip.
Internal emails
Internal emails can be shorter and more direct than external ones. Your colleagues know the context, so you don't need to rebuild it every time. Get to the point, make your ask clear, and keep it conversational. If the exchange is going back and forth more than twice, it's probably quicker to just have the conversation.
How to write an email quickly
Writing emails fast doesn't mean writing them carelessly. It means having a reliable approach so you're not starting from scratch every time.
Use a simple template: Most work emails follow the same structure: reason for writing, context or detail, call to action, sign-off. Once that becomes instinctive, you'll spend less time deciding how to start and more time just writing.
Write the call to action first: If you know what you need the reader to do, write that sentence first. Everything else in the email exists to support it. Starting with the ask makes it easier to keep the rest tight.
Don't over-edit: Most professional emails don't need three drafts. Write it, read it once, fix anything unclear, and send. Perfectionism costs more time than the occasional imperfect sentence.
Set a time limit: Give yourself two minutes for a standard reply. It sounds arbitrary, but a deadline focuses you. If you're still writing after two minutes, the email is probably too long.
Let drafts do the heavy lifting: For professionals dealing with high email volume, the most effective time-saver is removing the blank page entirely. Tools like Fyxer work inside Gmail and Outlook to generate draft replies in your own voice before you've even opened the message, so reviewing and sending takes seconds rather than minutes.
Common email mistakes to avoid
Even experienced professionals who have sent thousands of emails make these. Knowing what to watch for is just as useful as knowing what to do.
Vague subject lines: "Following up" and "Quick question" tell the reader nothing. If your subject line doesn't give them enough to prioritize your email, it'll wait. Sometimes indefinitely.
Burying the point: If the reader has to get to paragraph three to understand what you need, you've already lost some of them. Lead with your reason for writing, not the background to it.
Replying all unnecessarily: Before you hit reply all, ask whether everyone on that thread actually needs your response. Most of the time, they don't.
Sending without proofreading: A typo in a casual message to a colleague is one thing. A typo in a client proposal or a job application is harder to recover from. Read it once before you send.
CCing too many people:CC is for people who need to be informed. It's not a way of covering yourself or demonstrating activity. Overcrowding the CC field creates noise for everyone.
Using the wrong tone: Going too formal with a long-term colleague can feel cold. Going too casual with someone you've never met can read as unprofessional. When in doubt, start formal and adjust from there.
Write your emails with confidence
Good email habits compound. The professionals who respond faster, get replies sooner, and move work forward aren't the ones with the most elaborate systems. They're the ones who made a reliable structure second nature. Use these seven steps as your baseline and tighten from there.
Writing emails FAQs
What should I write in the subject line of an email?
Keep it short and specific, around 5 to 8 words. Instead of "Question," try "Question about project timeline." If there's a deadline or action needed, put the date up front. The goal is simple: tell people what's inside so they can decide whether to open it now or later.
How can I write an email that gets a response?
Make it easy to reply. Say what you need right at the start, keep it brief, and be specific about what you're asking for. Instead of "Let me know what you think," say "Can you review this and send feedback by Friday?" People respond faster when they know exactly what you need and when you need it.
What's the best way to start an email?
Use a greeting that fits your relationship with the person. "Hello [Name]" or "Hi [Name]" work for most situations. Then jump straight into why you're writing: "I'm reaching out about the budget" or "Following up on our meeting yesterday." Skip the generic "I hope this finds you well" unless you actually know the person. Just get to the point.
How long should an email be?
Short enough to respect people's time, long enough to be clear. Most work emails should be 50 to 125 words, around 3 to 5 paragraphs. If you're writing more than that, use bullet points or consider whether a quick call might work better. Remember, lots of people read email on their phones, so shorter is usually better.
Should I use formal or informal language in my emails?
It depends on who you're talking to. Go formal with senior leaders, clients, or people you don't know well. You can loosen up with teammates you work with every day. When you're not sure, start formal and then match whatever tone they use when they reply. Different industries have different styles too. A startup might be more casual than a law firm, and that's fine.
How do I know if I should send an email or use another form of communication?
Use email for things that aren't urgent and when you need a paper trail. Pick up the phone for urgent stuff, complicated discussions, or sensitive topics where tone really matters. Use chat for quick questions. Schedule a meeting when multiple people need to hash something out together. And here's a good rule: if your email is getting super long or you're struggling to explain something, just call instead.
What is the correct format for a professional email?
A professional email has seven elements: a specific subject line, a named greeting, an opening sentence that states your reason for writing, a short focused body, a clear call to action, an appropriate sign-off, and a full signature. Follow that structure and the rest of the writing becomes easier. The step-by-step guide above covers each element in detail.
