Email Writing Best Practices

The structure of an effective email in English follows a simple formula:

Let's break down each element:

1. Use a Professional Email Address

Your email address creates a first impression.

For business emails, use a simple, professional address like:

• firstname.lastname@company.com
• firstname_lastname@company.com

Avoid informal handles like:

• cooldude123@anymail.com
• babygirl@cutemail.com

Using your real name lends credibility, while informal addresses seem unprofessional.

For academics, use your official school email when emailing teachers, admissions staff, or classmates for assignments.

2. Write a Clear, Specific Subject Line

The subject line is your email's headline—it must catch attention fast.

Use a specific, benefit-driven subject line like:

• Request for English fluency program dates
• Question about scholarship application

Avoid vague subjects like:

• Urgent
• Important question
• Follow up

Studies show concise, benefit-focused subject lines have higher open rates (Experian, 2024).

Subject lines under 50 characters also display fully on mobile devices.

3. Use the Proper Greeting

Who you are emailing determines the greeting you use.

For formal emails:

• Dear Mr./Ms. [Last Name]
• Dear [Title] [Last Name] (e.g. Dear Professor Smith)

For informal emails:

• Hi [First Name]

• Hello [First Name]

• Avoid "Hey" or "Yo" for professional correspondence.

Match the formality of your greeting to the recipient and situation. Err on the formal side if unsure.

4. Craft a Focused, Scannable Body

The body contains your message. To maximize clarity:

• Highlight key requests in bold.
• Use bulleted lists for multi-step instructions.
• Keep paragraphs short—3-4 sentences.
• Use line breaks between ideas.

This scannable format makes your content easy to digest.

5. Close with a Clear Call to Action

End your email by summarizing next steps:

• Thank the recipient
• Recap any requests
• Provide contact information

This drives the action you want, like:

"Thank you for considering my application. I look forward to your response regarding the next interview steps. Please let me know if you need any additional information from my side."

6. Add an Appropriate Signature

A professional signature includes:

• Your full name
• Job title/role
• Company name
• Contact information

Formatting your signature like this:

John Smith Marketing Assistant ABC Company john.smith@abccompany.com (123) 456-7890

Adds context so recipients can easily contact you.

Add an Appropriate Signature

Common Email Writing Mistakes to Avoid

Even fluent English speakers make mistakes writing emails. Here are some key errors to avoid:

1. Using Vague Subject Lines

Subject lines like "Urgent" or "Important Question" give no context, reducing open rates.

Fix it: Always include keywords and specifics in your subject line:

Bad: Urgent

Good: Question about English fluency program deadline

2. Missing Greetings or Signatures

Skipping greetings and signatures seems casual—but looks unprofessional.

Fix it: Even quick replies merit a greeting and signature for relationship-building.

3. Writing Overly Long Emails

Long blocks of text feel overwhelming.

Fix it: Break content into concise paragraphs of 3-4 sentences. Use bulleted lists to simplify instructions.

4. Embedding Unclear Requests

Burying asks within long paragraphs is confusing.

Fix it: Clarify all requests up front in bolded sentences.

5. Using the Wrong Tone

Informal tone might seem friendly, but isn't always appropriate professionally.

Fix it: Mirror the recipient's tone, or err on the formal side if unsure.

6. Neglecting Proofreading

Typos and grammar errors appear unprofessional.

Fix it: Re-read every message before sending. Let important emails sit overnight before proofing again.

Advanced Tips from Experts

Take your email writing to the next level with these pro techniques:

Use "You" Focused Language

Emphasizing "you" makes messages feel personal and engaging. For example:

"I've attached the report you requested. Let me know if you need anything else from my side to finish your analysis."

Subtle changes like this connect directly with recipients.

Match Tone to Situation

Adjust your tone to fit different contexts:

• Formal emails: Use complete sentences. Avoid contractions like "can't"—spell them out instead.

• Informal emails: Express personality. Contractions and emojis add human warmth when appropriate.

• Urgent emails: Get to the main request quickly. Use concise language and stick to high priority items.

• Relationship-building: Don't be afraid to ask non-work questions, like "Hope you had a nice weekend!"

Personalize Templates

Reuse email templates to save time, but avoid sending duplicate messages:

• Swap out placeholder names for real ones
• Change greeting based on relationship
• Update specifics like dates or locations

Even small personalization touches build rapport.

Go Mobile

Optimize your emails for mobile screens:

• Use clear, bold formatting
• Keep lines under 60–70 characters
• Link to documents rather than attaching them

Over 50% of emails are opened on mobile devices (Litmus, 2025). Formatting for mobility makes you accessible.
