1. What Is a Cold Email and Does It Work?
A cold email is an unsolicited email you send to someone at a company you want to work at — without an open position being advertised. You're reaching out directly, introducing yourself, and asking if there's an opportunity.
Does it work? Yes — especially in India's startup and product company ecosystem. Many small-to-mid size tech companies in Kerala, Bangalore, Hyderabad, and Pune hire interns through referrals and direct outreach, not job boards. If you wait for a posting on Internshala or LinkedIn, you're competing with 500 applicants. A well-written cold email to the right person often has a response rate of 20–40%.
Most engineering students never send cold emails because it feels uncomfortable. That means the ones who do immediately stand out. Initiative is rare — and every company values it. A student who researches a company and writes a thoughtful email is already ahead of 95% of applicants.
2. Research Before You Write
The biggest mistake students make is sending the same generic email to 50 companies. Recipients can tell immediately, and they delete it. Spend 10 minutes researching before you write a single word.
Find the Right Person to Email
- For startups (under 50 people): email the Founder or Co-Founder directly — they make internship decisions
- For mid-size companies: email the Engineering Manager or Head of Engineering
- For large companies: email an HR/Talent Acquisition person who handles student programs
- Find them on LinkedIn — search "[Company Name] + CTO / Engineering Manager / HR"
What to Know Before Writing
- What does the company actually build or sell?
- What tech stack do they use? (check job postings even if not for interns)
- Have they posted anything interesting recently? (blog, LinkedIn post, product launch)
- Do you have any skill that directly applies to what they do?
3. The Subject Line
The subject line determines whether your email gets opened. Most students write terrible subject lines like "Internship Request" or "Seeking Opportunity." These get ignored.
The Formula That Works
ECE Intern — [One specific thing about them] — [Your College]
Good Examples
- "ECE Intern — Saw your ESP32 fleet management demo — NIT Calicut"
- "Software Intern — Interested in your AI agriculture project — College of Engineering Trivandrum"
- "Robotics Intern — Built a PID line follower, love your automation work — CUSAT"
What NOT to Write
- "Internship Request" — too generic, immediately filtered
- "Seeking Valuable Opportunity" — sounds like a form letter
- "I am writing to express my interest..." — never use this in a subject
- "Urgent: Internship Application" — the urgency is yours, not theirs
4. The 4-Part Email Structure
A cold email should be short — under 150 words in the body. Here's the structure:
- Opening — Why this company specifically (1–2 sentences). Mention something real and specific. This proves you're not sending a mass email.
- Who you are — Most relevant thing only (2 sentences). Year, branch, college, and the one thing most relevant to their work — a project, a skill, or a relevant course.
- The Ask — Specific and honest (1 sentence). Don't say "any opportunity." Say "a 4–6 week internship in your embedded systems team this May."
- Close — One clear next step (1 sentence). Ask for a 15-minute call, or mention you've attached your resume. Don't leave it open-ended.
5. The Complete Template
Subject: ECE Intern — [Something specific about them] — [Your College] Hi [First Name], [Opening: One specific thing you noticed about their work] I came across [Company Name]'s work on [specific project/product/post] and found it genuinely interesting — especially [one detail that connects to your skills or interests]. [Who you are: 2 sentences max] I'm [Your Name], a [Year] year ECE student at [College Name], [City]. I've been working with [Arduino/ESP32/Python/etc.] and recently completed [one relevant project in one line]. [The Ask: Be specific] I'm looking for a [4–6 week] internship in [May–June / any period] and would love to contribute to [something specific they work on]. [Close: One clear action] Would you be open to a 15-minute call to explore if there's a fit? I've attached my resume and a link to my GitHub below. Best regards, [Your Name] [College] | [Branch] | Batch [Year] GitHub: github.com/yourusername Phone: +91 XXXXXXXXXX
Do not attach your resume in the first email unless asked. Mention it's available if they'd like to see it. Attachments from unknown senders often go to spam, and it signals you haven't read basic email etiquette. Paste your GitHub and LinkedIn links in the signature instead.
6. Following Up
Most people who don't reply aren't ignoring you — they're busy and your email got buried. One follow-up email, sent 5–7 days later, is professional and expected.
Subject: Re: [same subject line as before] Hi [First Name], Just following up on my email from [date]. Completely understand if this isn't the right time — wanted to check in case it got buried. Happy to send more information or have a brief call if that's easier. Thanks, [Your Name]
Send exactly one follow-up. If there's no response after two emails, move on — following up a third time will only make a negative impression.
7. Common Mistakes to Avoid
- Emailing info@ or contact@ — these go to a general inbox, rarely to anyone who makes decisions. Find a real person's email on LinkedIn.
- Generic opening lines — "I am a student interested in your company" tells them nothing. Be specific.
- Writing too long — if your email is more than 200 words, cut it. Nobody reads long emails from strangers.
- Spelling the company name wrong — check. Then check again. This mistake kills your credibility instantly.
- Begging language — "Please give me a chance" or "I desperately need this" creates the wrong dynamic. Be professional and confident.
- No specific ask — "If there are any opportunities" is too vague. Say exactly what you want and when.
- Sending from a personal email like coolboy123@gmail.com — use your college email or a professional Gmail (firstname.lastname@gmail.com).
