Email Etiquette vs. Netiquette

Before we dive into the golden rules, it’s helpful to distinguish email etiquette from the broader concept of netiquette (internet etiquette). While netiquette covers general online behavior—forums, social media, chat—email etiquette focuses specifically on the conventions and expectations of professional email communication.

Netiquette includes things like respectful forum posts, not spamming chat rooms, and using emoticons responsibly.
Email Etiquette zeroes in on structuring messages, tone, formatting, and timing for workplace or client correspondence.

Think of netiquette as the umbrella, and email etiquette as the tailored suit you wear when you send that all‑important business email.

10 Golden Rules of Email Etiquette

Here are ten non‑negotiable rules—backed by experts at Forbes —that will ensure your emails always make the right impression.

1. Craft a Clear, Specific Subject Line

A vague subject like “Update” or “Question” buries your email. Instead:

Good: “Q2 Budget Proposal Attached for Review”

Tip: Keep it under 7 words and include the main action (e.g., “Proposal,” “Follow‑Up,” “Request”).

2. Use an Appropriate Greeting and Salutation

Jumping straight into the message feels abrupt. Always open with:

“Hi [Name],” — casual but professional
“Hello [Team/Department],” — for group emails
“Dear [Dr./Ms./Mr. LastName],” — when extra formality is required

Insight: I once received “Hey!” from a C‑level exec and immediately questioned the email’s legitimacy—tone matters!

3. Mind Your Grammar, Spelling & Punctuation

Typos and misplaced commas undermine credibility. Follow proper email punctuation:

Use periods to end complete thoughts.
Avoid run‑on sentences.
Don’t overuse exclamation points or emojis in professional contexts.

4. Keep Content Concise and Scannable

The average professional spends just 15 seconds reading an email. Structure your message to help them:

Short paragraphs (3–4 lines)
Bullet points for multiple items
Bold only key phrases

5. Maintain a Respectful, Professional Tone

Email isn’t casual chat. Avoid:

ALL CAPS (it feels like shouting)
Slang or jargon your recipient may not know
Negative words like “obviously” or “unfortunately” when unnecessary

6. Respond in a Timely Manner

In a corporate setting, 48 hours is often the maximum acceptable response time. If you need more time:

“Thank you for your email. I’m gathering the necessary details and will update you by Thursday.”

7. Format for Readability

Use a legible font (Arial, Calibri, or the default system font).
Stick to standard font sizes (10–12pt).
Include a professional signature with your name, title, and contact info.

8. Proofread Before Hitting “Send”

Always do a final check—read your email aloud or use tools like Grammarly to catch errors you might miss.

9. Avoid “Reply All” Unless Essential

Unnecessary “Reply All” responses clutter inboxes and frustrate teams. Only include everyone if their input or awareness is truly needed.

10. Use a Professional Email Address

Your email address is part of your personal brand. Avoid nicknames or years; choose a format like:

firstname.lastname@yourdomain.com
