Every guide to the cold email for a startup internship is written by the person sending it, or by a company selling email software. We sit on the other side. EX EPIC Academy reads applications for 78 open internship positions inside live ventures in Bali, and most of the notes that reach us are the same note with a different name at the bottom. This is what the inbox looks like from here, what gets deleted in five seconds, and the shape of the few emails that get a reply. ## The short answer Send it to one named person at a company under about 50 people. Keep it under 100 words. Open with one true, specific thing about them, give one link to something you built that a stranger can check, say what you would do in your first weeks, and end with a yes-or-no question. Follow up twice, a week apart, with something new each time. Most of your emails will still get nothing back, and that is the arithmetic working, not a verdict on you. ## Why a cold email beats the portal for startup internships ### What the data actually says about reply rates The best first-hand numbers come from a Dorm Room Fund investor who started with a blank resume. He sent 79 emails to founders of VC-backed startups, got 30 responses, met 11 of them and received one offer, a product internship at a Series A company. He reports a response rate around 40% that was the same before he had any relevant experience, and that the founder who hired him had read the student's Substack before the call and was already ready to hire. That is the optimistic end. The aggregate benchmarks are lower and more useful for planning. A cold email platform's modelled campaign puts 100 personalised emails at an 11.5% reply rate, 7% turning into conversations and 2% into offers, with companies under 30 employees replying at 15% against 4% for companies over 100, and a founder or CEO replying at 14% against 2% for an HR inbox. Those figures are vendor aggregates, not one student's send, so treat them as a floor to plan around. A third source gives the cleanest experiment. A writer who sent 14 emails to general info@ addresses got zero replies; the next batch of 11, sent to named people with two follow-ups each, got 4 replies and one internship offer. His conclusion: the difference was not the writing. It was who received it and whether he followed up. ### Roles that get created, not filled The portal puts you in a stack. The email puts you in a conversation with someone who can invent a role. The Dorm Room Fund author notes he has never been offered a role that already existed; every internship he got was created around him after a founder was impressed. A 22-year-old media graduate told Business Insider she sent about 30 traditional applications with no idea whether anyone saw them, then one cold email to a startup CEO got her hired as a business development intern. And on a Reddit thread where a final-year student with two deployed machine learning apps still could not land a single internship, the replies did not say apply harder. They said cold outreach and open source. If you are still building the list of companies to write to, start with where to find startup internships. ## What the person on the other end sees ### The five-second read Here is the honest mechanics of our inbox, and of any founder's. One guide estimates a founder gives an unknown sender about 15 seconds. In practice it is faster. We read on a phone, between two other things, and we are deciding one question: did this person write to us, or to fifty companies with the name swapped? The subject line and the first sentence answer that. Nothing below them gets read until they pass. ### The three openers we delete The first is the passion opener. "I am a passionate and driven student looking for an opportunity." An email-tool team put it bluntly: nobody cares, open with something about their company, not about yourself. We would add that "passionate" is the single most common word in our inbox, which makes it the least informative. The second is the vision opener. A founder's associate applicant to a YC-backed company sent the line "Your vision really resonates with me. Would love to connect and contribute to the mission" and got no response; his follow-up three days later worked, because it finally said something specific. Vision, mission, journey and resonate are the words that tell us the sender has not read anything we published. The third is the open ask. "Any opportunities or advice would be appreciated." That sentence hands the work back to the reader. The easiest response to an undefined request is no response. ### The one line that gets us to click A link to a thing. Not a description of a thing, a link to one: a deployed app with a real user, a repo with real commits, a teardown of our own onboarding, a short written piece. A first-year international student with no work experience landed an internship at a startup and later asked the co-founder why he got the interview. The answer was four words: "Your cold email was concise." Concise is possible only when there is a link doing the talking. The note we reply to has the thing you built, the link, one specific reason you want to be here, and one thing you would do in your first week. If you do not have the thing yet, that is the real bottleneck, and our guide on how to build a portfolio with no experience is the place to start before you write a single email. ## Who to send it to ### Company size decides the recipient Whether the founder is the right target depends entirely on headcount. The same email-tool guide lays out the rule: at 1 to 10 employees the founder makes every hiring decision; at 11 to 30 the founder is still probably the right person; at 31 to 50 a department head or team lead is preferred; from 51 to 200 you want the hiring manager; and above 200 the CEO will never see it. It also reports a Nature hiring survey in which 43% of senior leaders said cold emails are an effective way for candidates to get noticed, and sets the expectation at 10 to 20% replies for well-targeted emails to companies under 30 people. Within a small startup, pick the person you would actually report to. A named engineer or first marketer beats careers@ every time. ### Finding the address A student-focused guide gives the practical pattern: most small companies use firstname@company.com, then firstname.lastname or initial plus last name if that bounces, and tools like Hunter, ContactOut and Clay exist to check. The same guide makes the structural point that explains why this works at all: a startup founder gets far fewer good, short, specific emails from competent people than you would guess, and hiring is near the top of their list of problems. Verify the address before you send. A bounce costs you the thread. ## The 90 word structure that gets replies ### Subject line Under 60 characters so it survives a phone screen, specific enough to prove you wrote it for them. A job-search blog's working formulas: "ML intern who built a citation classifier", "Sarah Chen suggested I reach out", "Built openbenchmarks.io, exploring Stripe internship". On its avoid list: "Internship Application", "Exploring opportunities" and "Passionate about [Company]". A good test is whether the subject line could be sent to any other company unchanged. If yes, rewrite it. ### Line by line Four lines, in this order, each doing one job. 1. Observation. One true, specific thing about their product, post or launch. Fifteen to twenty words. "I saw your product" beats "I admire your company". 2. Proof. What you can do, with one link or one number. Twenty to twenty five words. "I built a Chrome extension that 400 people use" is a fact someone can react to. "I have worked on several projects" is invisible. 3. Contribution. What you would do for them in the first weeks, named concretely. Fifteen to twenty words. 4. Ask. One question that takes one word to answer. Ten to fifteen words. "Are you taking interns this summer?" or "Worth a 15 minute call?" No attachment in the first email. Link your proof and offer a one-page resume if useful. Sign with your name and one link, not three. ### Pre-send checklist Under 100 words. Says who you are in the first line. Contains one true, specific thing about their company. Contains at least one number or one link about your own work. Has exactly one ask, phrased as a question. Goes to a named person. Contains no sentence you would be embarrassed to say out loud. Contains none of the three openers above. ## Three cold emails we would reply to (annotated) These are ours, written to the structure above. Swap the bracketed slots, but keep the length. ### The "I used your product" note > Subject: [Product] intern who found the CSV bug
Hi [Name], I am [Your name], a final-year [major] student at [University]. I have used [Product] for [task] since [month] and noticed [one specific observation, e.g. the export drops rows with commas in the name field]. I wrote a small script that fixes it on my side: [link]. I would like to intern on your [team] this [term] and could start with exactly that kind of edge case. Would you be open to an intern this [term]? Why it works: the observation proves you used the product, the link proves you can act on it, and the ask is a yes or no. Eighty one words. ### The "I built something in your space" note > Subject: Built a [project type] in your space
Hi [Name], I am [Your name], second-year [major] at [University]. I built [project], a [one-line description], here: [link]. It handles the same problem [Company] works on, [name the overlap]. [One number: users, rows, hours saved]. I am looking for a [term] internship where I would own a piece of [specific area] rather than watch one. Are you taking interns this [term]? Why it works: the link is in the first two lines, the overlap is named, and the sentence about owning a piece tells a small team what kind of person you are. Seventy five words. ### The "here is my first week" note to a program > Subject: AI track: what I would ship in week one
Hi [Name], I am [Your name] from [city]. I read that your interns are placed inside live ventures and present what shipped every Friday. I built [project] for [a real user, e.g. a tutoring centre], live here: [link], and the second version added [feature] after their feedback. In my first week I would [one concrete deliverable for one of your ventures]. Is the [track] track still taking applicants for [cohort]? Why it works: it references something true about the program rather than its "vision", it shows a built thing with a second iteration, and it names a week-one deliverable. This is, almost word for word, the structure of the notes that move to the top of our pile. ## Follow-up: where most of the replies come from The leaderr.io writer's finding is the one to internalise: most replies come from the follow-up, not the first message. The benchmark data agrees, reporting a 49% lift in reply rate from the first follow-up, and a modelled first offer arriving 16 days after the first email, after a CTO replied within three hours, a 20-minute call the next day and a short take-home task. The schedule that works: day 1 the email, day 5 a two-sentence bump with one new detail, day 12 a new angle such as a launch they just shipped or a feature you added, then stop. Reply in the same thread so the original subject carries over. Keep each follow-up shorter than the last and add something: a fix you shipped, a sketch of how an intern could deliver one thing in a month. Two follow-ups is the limit for a cold thread, after which silence is your answer for this season. Two outliers are worth knowing so you do not misread them. Tristan Walker, an MBA student with no startup background, emailed the Foursquare founder eight more times before getting a reply, started by signing up merchants for free, and became the company's VP of Business Development. The same post tells how Alessa Massa spent four hours mocking up her resume as a Morning Brew newsletter and became the company's 13th employee. Eight follow-ups is not the method. The method is that both of them did a piece of work before asking for anything. Once a conversation is open, the rules change. The startupmap.one case shows a candidate who kept a YC-backed company warm through two months of near silence with short, pressure-free check-ins that each had a reason to exist, and who finally got the truth with a five-word question, "where's your head at right now". Every check-in got a warm reply, and the process ended with an invitation to fly out for a trial. ## What happens after the reply Take the call, even if it is ten minutes. Open with the demo and run it live. Expect a small scoped task before any offer; small teams hire on a sample of work, not on an interview performance. If the reply is "not hiring right now", ask for a short project or a call anyway, because a human read your email, which is further than most get. If the program you are writing to is ours, know what the reply leads to. EX EPIC Academy places interns in operational roles at ventures such as Zero X in waste to energy, Gemino AI in automation and LIV Urban Sanctuary in wellness, for four to six months on site in Canggu, Bali, unpaid with potential for a full time transition. The cohort is students from 26 nations working on 15 live projects, with no grades and no exams, inside a parent group that reports 250 plus operators trained and deployed through the Academy. Unpaid is a real cost, which is why we wrote separately about whether a startup unpaid internship is worth it, and about the outcome question itself in are startup internships worth it. If you are weighing destinations as well as formats, our guide to an AI internship abroad covers what a real one looks like, and if the AI track is the one you want, read how to get an AI internship with no experience before you write to us. Then write the email. One named person, one link, one ask. You ship or you don't, and the email is the first thing you ship. ## FAQ ### How long should a cold email for a startup internship be? Under 100 words and five sentences or fewer, readable on a phone without scrolling. The benchmark data puts emails under 100 words at a 12% reply rate against 6% for emails over 200 words, so every extra paragraph roughly halves your odds. ### Should I attach my resume to a cold email for an internship? Not in the first email. An unsolicited attachment adds friction and pattern-matches to spam. Link your proof in the body and offer to send a one-page resume. When they say yes, send one that leads with the same proof you mentioned. ### Is it OK to cold email a startup that is not hiring interns? Yes, and it is often the better target. A company with no posted role has no stack of applicants, and a small team can create a role around a person who impresses them. The Dorm Room Fund investor quoted above was never offered a role that already existed. ### How many cold emails do I need to send to get a startup internship? Plan on 20 to 30 well-researched emails over two to three weeks, each with two follow-ups, and judge the batch rather than any single email. Benchmarks put 100 personalised emails at 8 to 12 replies and 1 to 3 offers over six to eight weeks; the best first-hand campaign got one offer from 79 emails. ### What is the best day and time to send a cold email to a founder? Benchmarks favour Tuesday to Thursday between 8 and 10 AM in the recipient's time zone, at 13% replies against 7% for Monday or Friday afternoons. Timing is the weakest variable on the list. Who you send to, how short it is and whether you follow up matter far more.
