Professional Email Structure

  1. 1

    Subject line — be specific

    The subject line determines whether your email gets opened. Be specific: "Meeting request — Thursday 2pm" beats "Meeting". "Invoice #4521 — payment query" beats "Question". Avoid vague subjects like "Hi", "Following up" or leaving it blank.

  2. 2

    Greeting

    Match the formality to the relationship. First contact or formal: "Dear Mr/Ms [Last name]," or "Dear [First name],". Established colleague: "Hi [First name]," works fine. Avoid "Hey", "To Whom It May Concern" (too cold and impersonal), or no greeting at all.

  3. 3

    Opening line — state your purpose

    Get to the point in the first sentence. "I am writing to enquire about..." or "I wanted to follow up on our conversation about..." Avoid padding like "I hope this email finds you well" in professional contexts — most people find it empty.

  4. 4

    Body — one main point, short paragraphs

    Keep paragraphs to 2–3 sentences. If you have multiple points, use numbered or bulleted lists — they are far easier to read and respond to than dense paragraphs. Put the most important information first, not last.

  5. 5

    Clear call to action

    End with a specific request: "Could you please confirm by Friday?" or "Let me know if you have any questions." Vague endings like "Let me know your thoughts" make it unclear what you want the recipient to do next.

  6. 6

    Sign-off

    Formal: "Yours sincerely," (if you know the name) or "Yours faithfully," (if you used "Dear Sir/Madam"). Standard professional: "Kind regards," or "Best regards,". Casual colleague: "Thanks," or "Cheers," is fine. Always include your full name and contact details in your signature.

Common professional email mistakesReplying to all when only the sender needs to know. Forgetting the attachment after mentioning it. Sending before proofreading. Using all caps (reads as shouting). Putting multiple unrelated topics in one email — send separate emails instead.
Before you hit sendRe-read the email once as the recipient. Is it clear what you want? Have you answered all their questions? Is the tone appropriate? Is the right person in To vs CC? Most email regrets come from sending too quickly.

Response Time

Professional standard is to reply within 24 hours on working days. If you cannot give a full response, acknowledge receipt: "Thanks for your email — I will get back to you with full details by Thursday."

Frequently Asked Questions

CC (carbon copy) sends a visible copy to additional recipients — everyone can see who was CC'd. BCC (blind carbon copy) sends a copy without other recipients knowing. Use BCC when emailing a group to protect privacy, or to copy yourself for record-keeping without the recipient knowing.
Wait at least 2 working days, then forward your original email with a brief note: "Hi [name], just wanted to follow up on my email below — let me know if you need any further information." Keep the tone neutral and assume they are busy, not ignoring you.
Generally no in formal business contexts, especially first contact or with senior people. In established casual working relationships a single emoji can be fine. When in doubt, leave them out.
