Cold emailing means writing to someone who has not advertised an opening, or who has advertised one without a clear application route, and asking to be considered. Done well, it reaches internships that never appear on job boards. Done badly, it is spam that nobody reads. This guide covers when cold outreach is worth your time, how to find the right person, and three templates you can adapt.
When cold emailing actually works
Cold email works best where hiring is informal and the person reading your message is also the person who decides. That usually means:
- Early-stage startups, where a founder or team lead may hire an intern the week a need appears. Browse startup internships to see which kinds of firms hire interns and what they ask for.
- Small firms and agencies: CA firms, design studios, marketing agencies, law chambers and consultancies.
- Research labs and professors at universities and institutes, for summer or semester research work. Listed research internships are a good benchmark for what labs expect.
City matters less than you think: a design studio in Mumbai or a lab in Pune may happily take a remote intern for a defined task. It works poorly at large companies with structured campus and off-campus processes. There, apply through the official route and use our off-campus drive guide instead.
Finding the right person to write to
A well-written email to a generic inbox rarely gets read. Aim for the person who runs the team you want to join.
- Start from the company website: the About, Team, Contact and Careers pages. Many small firms list a hiring or careers address on their careers page.
- Check the firm's page on our company directory and any open roles listed there, including jobs by company.
- For labs, the faculty profile page on the institute website usually lists research interests and an official contact route.
- If no individual contact is published, use the official careers or general address and address the email to the relevant team lead by role.
Only use contact details the organisation has published for this purpose. Never guess or scrape personal addresses.
Before you write, spend ten minutes on their actual work: the last few blog posts, the product pages, the campaigns they ran or the papers the lab published this year. You need one specific, honest observation for the first line. If the firm has posted similar roles before, for example digital marketing internships or design internships, read those descriptions to learn which tools and tasks they value, and mirror that language in your proof section. Run your resume through the ATS checker as well, because a small firm may still forward it into a formal system.
Subject lines that get opened
The subject line should say who you are and what you want in under ten words.
- Content intern for [Month] – 2nd-year BA student, samples attached
- Data analysis internship request – Python + Excel, [City]
- Research internship: interest in [specific topic] – [Your college]
- Following up: design internship, portfolio link inside
Avoid vague subjects such as "Request" or "Internship", and never use all capitals.
The five-part structure
| Part | Length | What it does |
|---|---|---|
| 1. Hook | 1 sentence | Shows you know what they do: a product, project or paper |
| 2. Who you are | 1–2 sentences | Course, year, college, city |
| 3. Proof | 2–3 sentences | One relevant project with a link and an outcome |
| 4. The ask | 1–2 sentences | Role, dates, remote or in-office, hours per week |
| 5. Close | 1 sentence | Easy next step and thanks |
Keep the whole email under 150 words. If you have no project yet, build a small one first using our learning hub; a cold email without proof rarely works. Attach a one-page resume as a PDF named with your full name, and put your key link in the body, not only in the attachment. The resume builder exports a clean PDF.
Three templates with placeholders
Template 1: startup or small firm
Subject: Marketing internship for [Month] – [Course], [City]
Hi [name], I have been following [company]'s [product/campaign] and liked how [one specific observation]. I am a [year] [course] student at [college] in [city].

I would like to intern with your marketing team for [8/12] weeks from [date], [remote/in-office], [hours] hours a week. Could we have a 10-minute call this week or next? Thank you for reading. [Your name], [your email], [portfolio link]
Template 2: research lab or professor

Follow-up timing and tracking
- Send the first email on a weekday morning.
- Follow up once after five to seven working days, replying in the same thread.
- If there is still no reply after a second week, move on. Two messages in total is the limit.
- Track every email in the same sheet you use for applications. Our 30-day job search plan has a tracker layout.
Send cold emails in small batches of five to ten a day, each personalised. Fifty identical emails in one evening are easy to spot and hurt your chances.
What not to do
- Do not send the same text to everyone with only the company name changed.
- Do not write "I will do any work". Name the team and the task.
- Do not attach five files. One resume, plus a link.
- Do not ask for a stipend figure in the first email; that comes once there is interest. Our stipend negotiation guide covers that conversation.
- Do not pay anyone who replies asking for a registration or training fee. Read our list of internship scam red flags.
Keep applying to listed roles alongside cold outreach. Open internships, remote internships and content writing internships are good places to start while you wait for replies.
Frequently asked questions
Is it okay to cold email a company for an internship?
Yes, especially startups, small firms and research labs where hiring is informal. Keep the email short, specific and polite, use only contact details the organisation has published, and follow up no more than once.
How long should a cold email for an internship be?
Under 150 words is a good limit. The reader should understand who you are, one piece of proof and what you are asking for without scrolling.
When should I follow up if there is no reply?
Wait five to seven working days and reply in the same thread with one new piece of information, such as a recent project. If there is still no response after another week, move on.
Should I attach my resume to a cold email?
Yes, attach a one-page PDF resume named with your full name, and also put your most relevant link in the body of the email so the reader can check your work without opening the attachment.
