Knowing how to write a professional email is one of those skills that becomes useful almost immediately, whether you’re applying for a job, following up after an interview, or reaching out to someone new in your field. It doesn’t need to be complicated, but there are a few things worth getting right from the start.
Why it matters
Emails create a first impression before you’ve met anyone in person. A well-written email signals that you’re organised, respectful of the other person’s time, and serious about what you’re asking. A poorly written one can undermine an otherwise strong application or inquiry before it’s even considered.
The good news is the basics are straightforward once you know them.
Start with a clear subject line
Your subject line is the first thing the recipient sees, and it often determines whether your email gets opened promptly or left for later. Keep it specific and relevant. “Application for Marketing Assistant role – Alex Taylor” tells the reader exactly what they’re opening. “Hi” or a blank subject line does not.
A good subject line is also searchable, so think about the keywords someone would use to find your email later.
Use an appropriate greeting
How you open an email sets the tone for everything that follows. If you know the person’s name, use it: “Dear Ms Nguyen” or “Hi James” both work depending on the context. If you’re unsure of someone’s name, check the organisation’s website or LinkedIn before defaulting to “To Whom It May Concern.” A little research goes a long way and shows initiative.
If the role or title is unclear, “Dear Hiring Manager” is a safe, professional fallback for job applications.
Get to the point early
State why you’re emailing in the first paragraph. Recruiters and busy professionals don’t have time to read through several sentences of preamble before finding out what you actually want. Something like “I’m writing to apply for the graphic design internship advertised on your website” is clear, direct, and respectful of their time.
If you’re following up on a previous conversation, briefly reference it so the recipient has context without needing to search their inbox.
Match your tone to the situation
Not every professional email needs to be stiff and formal. The right tone depends on who you’re writing to and why. A cold email to a senior executive warrants more formality than a reply to a friendly recruiter who signed off with “Cheers.”
A useful rule of thumb: mirror the level of formality the other person uses when they write back. Until then, err on the side of being slightly more formal rather than less. Avoid slang, abbreviations, and anything you’d only say in a text message.
Include the right details
If your email involves specific information, such as dates, times, documents, or questions, make sure they’re clearly laid out. Don’t bury a deadline in the middle of a paragraph, and if you’re attaching something, mention it explicitly in the body of the email rather than leaving the recipient to notice it themselves.
Check that any attachments are actually attached and named clearly before you hit send.
Close and sign off well
End with a short, polite closing line before your sign-off. Something like “Thank you for your time” or “I look forward to hearing from you” works well. Then choose a sign-off that fits the context: “Kind regards” and “Thanks” are both fine; “Cheers” is fine once you know someone; “Love” is not.
Your email signature should include your full name, phone number, and any relevant professional links such as a LinkedIn profile or portfolio. If you’re still at school or university, you can include that too. Keep it clean and simple.
Common mistakes to avoid
Even a well-structured email can fall flat if you overlook the basics:
- Sending without proofreading. Typos and grammar errors are easy to miss and easy to avoid.
- Using your personal email address. If you have a student or professional address, use it.
- Replying to the wrong thread or forgetting to update the subject line when the topic changes.
- Following up too soon. If you haven’t heard back, a week is generally a reasonable wait before sending a polite follow-up.
