Why Email Etiquette Matters in Business

In today's workplace, email is the most ubiquitous communication medium. Over 281 billion emails are sent per day, and that number keeps rising.

With email playing such a vital role, it's crucial to get your email etiquette right. Consider these statistics:

• 61% of professionals say poor email writing undermines a sender's credibility (WriteExpress, 2022).

• 45% of emails are opened based solely on the subject line according to Campaign Monitor. Strong subject lines boost open rates.

• Emails with improper tone or etiquette can damage business relationships, according to a Robert Half survey.

The bottom line? Honing your email etiquette, structure, and clarity will ensure your messages resonate for the right reasons. Let's learn how.

Anatomy of a Professional Email: Key Elements

A well-crafted professional email includes the following core components:

Anatomy of a Professional Email

Subject Line

The subject line appears in the recipient's inbox and determines if your email gets opened. Craft a clear, compelling subject line that:

• Clearly states the email's purpose in 6-10 words. E.g. "Meeting Request: Q3 Brainstorm Session".

• Contains keywords relevant to the content.

• Creates curiosity with words like "Re:" or "Update on...".

Greeting

The greeting sets the tone for your email. Use a formal greeting with the recipient's name and avoid casual phrases like "Hey":

Formal:

• "Dear Ms. Lee,"
• "Hello Mr. Johnson,"

Semi-formal (for familiar recipients):

• "Hi Jane,"
• "Good morning Nate,"

Body

The body contains the bulk of your content. To enhance readability:

• Use clear paragraph breaks to divide up sections.

• Highlight key info in bold but don't overuse (no more than 1 bold word/phrase per paragraph).

• Use bulleted lists for easy scanning.

Closing

End your email with an appropriate closing that matches the tone of your greeting. Some examples:

• "Best regards,"
• "Sincerely,",
• "Thank you,"

Follow with your name on the next line.

Signature

A professional signature includes your name, job title, company, phone number, email address, and website.

Keep the design clean and avoid large images or quotes.

How to Craft the Perfect Professional Email in 5 Steps

Now let's walk through the email writing process from start to finish:

How to Craft the Perfect Professional Email in 5 Steps

1. Set Your Purpose

Before writing, clarify exactly what you want to accomplish with the email.

Do you want to:

• Request a meeting?
• Follow up on a previous discussion?
• Share an update on a project?

Defining a clear purpose upfront leads to greater clarity for the reader.

2. Create a Descriptive Subject Line

Spend time crafting your subject line—as mentioned, this impacts whether the email gets opened.

Include:

• A clear summary of the topic in 6-10 words. E.g. "Request for Q4 Budget Review Meeting"

• Relevant keywords. E.g. "December Team Newsletter Update"

• Intriguing phrases like "Re:" or "Follow Up:" if applicable.

3. Structure Your Content

Organize the body clearly and logically to help readers digest your message:

• Open by directly stating your purpose/request. Get to the point right away.

• Elaborate on key details, with spacing and bullet points to segment info.

• Call to action—what do you want the recipient to do? Include next steps, if any.

4. Proofread Thoroughly

Before hitting send, double check for:

• Spelling and grammar errors—these undermine professionalism.

• Formatting inconsistencies like inconsistent bolding or odd spacing.

• Unclear sentences that need rephrasing for clarity.

Ideally, have someone else proofread as well.

5. Follow Up Politely

If you don't get a response within 1-2 days, send a friendly follow-up email re-stating your request or query.

It's easy for emails to get lost, so don't assume the lack of reply is anything personal! Persistence and politeness pay off.

FAQs About Professional Email Writing

Q: How long should a professional email be?

A: Ideally, keep professional emails concise at 3-5 paragraphs long (under 300 words).

State your purpose upfront, provide relevant details to support your request or message, and include a clear call to action. Avoid long-winded emails that bury the key info.

Q: Should professional emails include emojis or abbreviations like LOL?

A: Generally, avoid using informal language like emojis, text slang (LOL, BRB) or excessive exclamation points in work emails. These can undermine your professionalism.

However, occasional use of a smiley face or thumbs up emoji is acceptable in emails to colleagues you are familiar with, as long as the overall tone remains polite and appropriate. But avoid overusing emojis.

Q: How do I write an email signature on mobile?

A: On mobile devices, type your full name at the bottom of the email to indicate it is from you. You can set up an email signature in your mobile email account settings that automatically includes your contact details.

On the iPhone Mail app, go to Settings > Signatures to create one. On Gmail for Android, go to General Settings > Mobile Signature.

Q: What is the proper email closing and signature format?

A: A proper email closing includes a closing phrase like "Best regards," on one line, then skip a line before your name. For a full signature, put your name and title on line one, your company details on line two, then phone, email, and website details on lines three and four.

Example:

Best regards,

[Your name] [Job title] [Company name] [Phone number] [Email address] [Website]
