Why Email Matters

47%of emails are opened or ignored based on subject line alone

2.5 minaverage time spent on an email response

86%of professionals prefer email for business communication

3xhigher response rates with personalized subject lines

In both academic and professional settings, email remains the primary mode of formal communication. A well-written email can open doors, while a careless one can close them forever.

This guide covers everything from basic etiquette rules to advanced techniques for cold outreach, follow-ups, and workplace communication. By the end, you'll write emails that get read, get responses, and get results.

Key Takeaways

Your subject line determines if your email gets opened—make it count
Keep emails short and scannable—busy people skim, not read
Always proofread before sending—typos destroy credibility
Include a clear call-to-action—what do you want them to do?
Follow up strategically—persistence pays, pestering doesn't
Match your tone to the recipient and context

1. Email Fundamentals

Before diving into templates and techniques, get these basics right:

Professional Email Address

Use: [email protected] or [email protected]
Avoid: [email protected], [email protected]
If your name is taken, use initials or add a professional suffix (e.g., [email protected])

Email Signature

Create a professional signature that includes:

Your full name
Current role/major (e.g., "Computer Science, IIT Delhi")
Phone number (optional)
LinkedIn profile URL
Portfolio website (if applicable)

Example Signature:

Best regards,
Rahul Sharma
B.Tech Computer Science, IIT Delhi (2024)
linkedin.com/in/rahulsharma | +91 98765 43210

Reply Etiquette

Reply within 24 hours for professional emails
Use "Reply All" only when everyone needs the information
Keep the thread if context is needed, start fresh if not

2. Powerful Subject Lines

Your subject line is the gatekeeper. A boring subject means your email may never be opened.

Subject Line Best Practices

Be specific: "Application for SDE Intern - Rahul Sharma, IIT Delhi"
Keep it short: Under 50 characters displays fully on mobile
Include key info: Role, your name, college
Create urgency when appropriate: "Quick question about..."

Subject Line Formulas

For Applications

"Application for [Role] - [Your Name], [College]"

For Follow-Ups

"Following up: [Original Subject]"

For Networking

"[Mutual Connection] suggested I reach out"

For Cold Outreach

"Quick question about [specific topic at their company]"

For Thank You Emails

"Thank you - [Role] Interview"

Subject Lines to Avoid

❌ "Hi" (tells nothing)
❌ "Query" (too vague)
❌ "URGENT!!!" (looks spammy)
❌ "Please read this" (desperate)
❌ Blank subject (goes to spam)

3. Email Structure

Every professional email should follow this structure:

1. Greeting (1 line)

"Dear [Name]," or "Hi [Name]," depending on formality

2. Opening (1-2 sentences)

Who you are and why you're writing. Get to the point immediately.

3. Body (2-3 short paragraphs)

Main content with specific details. Use bullet points for readability.

4. Call-to-Action (1 sentence)

What do you want them to do? Be specific and make it easy to respond.

5. Closing (1-2 sentences)

Express gratitude, offer to provide more info, sign off professionally.

Pro Tip: If your email is longer than 5 sentences, consider if it should be a call instead. Long emails don't get read.

4. Tone and Formality

Match your tone to the recipient and the situation:

Situation	Greeting	Sign-off
Very Formal	"Dear Mr./Ms. [Last Name],"	"Respectfully,"
Formal (most business)	"Dear [First Name],"	"Best regards,"
Semi-Formal	"Hi [First Name],"	"Best," or "Thanks,"
Casual (colleagues)	"Hey [First Name],"	"Cheers," or "Thanks!"

Tone Tips

When in doubt, be more formal rather than less
Match the recipient's tone after they reply
Avoid ALL CAPS (reads as shouting)
Use exclamation marks sparingly (one per email max)
Be warm but professional—cold emails feel robotic

5. Templates for Every Situation

6. Follow-Up Strategy

Most emails don't get responses the first time. Strategic follow-ups are essential.

When to Follow Up

Applications: 5-7 business days after applying
After interview: Send thank you within 24 hours
Networking requests: 5-7 business days
Cold emails: 3-5 business days

[Brief 1-line reminder of your original request]

Follow-Up Rules

Maximum 2-3 follow-ups total
Space them 5-7 days apart
Keep each follow-up shorter than the previous
Add value if possible (new info, relevant article)
Know when to stop—no response after 3 attempts = move on

7. Cold Email Best Practices

Cold emails to people you don't know require special care:

Cold Email Formula (AIDA)

Attention: Hook with something specific about them
Interest: Show you've done research
Desire: Explain why you're reaching out (what's in it for them)
Action: Clear, easy ask

Tips for Higher Response Rates

Personalize the first line (mention their work, article, tweet)
Keep it under 150 words
Make the ask small (15-min call, vs hour-long meeting)
Send Tuesday-Thursday mornings for best open rates
Use their first name, not "Dear Sir/Madam"

Pro Tip: The best cold emails feel like warm emails. Find a genuine connection—mutual contact, shared interest, their public work—and lead with that.

8. Workplace Email Etiquette

Once you're in a professional environment, additional rules apply:

Reply All Etiquette

Only use when everyone genuinely needs the information
Never reply all for "Thanks" or "Got it"
Be mindful of long CC lists

CC and BCC

CC: People who need to be informed but not take action
BCC: Hiding recipients from each other (use sparingly)
Don't CC someone's boss to "escalate" without warning them first

Response Time

Acknowledge receipt within 24 hours, even if full response will take longer
"Thanks for sending—I'll review and get back to you by [date]"
Set expectations if you need more time

Internal vs External

Internal: Can be more casual, depending on company culture
External: Always err on the side of formality

9. Common Mistakes

❌ Vague subject lines

"Hi," "Query," "Help" tell the recipient nothing about content.

❌ Too long

People don't read long emails. Be concise.

❌ Typos and grammar errors

Shows carelessness. Always proofread.

❌ Wrong recipient name

Nothing says "copy-paste" like addressing someone by the wrong name.

❌ No call-to-action

If you don't ask for something specific, you won't get it.

❌ Sending angry emails

Never send an email when emotional. Draft it, wait a day, then revise.

❌ Forgetting attachments

Mention attachments in the first line so you don't forget.

Use short paragraphs (2-3 sentences max)
Avoid attachments when possible (link to cloud storage)
Make phone numbers and links clickable
Test how your signature looks on mobile

12. FAQs

When should I follow up on an email?

Wait 3-5 business days for normal inquiries, 5-7 days for job applications. Don't follow up more than 2-3 times total.

Should I use emojis in professional emails?

Avoid in first contact with professionals. Once you have rapport, occasional emojis may be okay depending on workplace culture.

What if I sent an email with a typo?

If it's minor, let it go. If it's significant (wrong name, wrong company), send a brief apology and correction.

Should I use "Dear Sir/Madam"?

Avoid if possible. Take 2 minutes to find the person's name. If truly unknown, use "Dear Hiring Team" or "Hello."

How long should a professional email be?

5-7 sentences is ideal. If longer is necessary, use bullet points and clear formatting so it's scannable.

Is it okay to send emails late at night?

Generally avoid—it may set unrealistic expectations. Use scheduling tools to send during business hours.

Email Like a Professional

Every email you send is a reflection of your professionalism, attention to detail, and communication skills. In a world of instant messaging, a well-crafted email stands out.

Take the extra minute to structure your thoughts, proofread your message, and consider how it will be received. It's a small investment that pays dividends throughout your career.
