To cold email a CEO, write four sentences: why them, what you do, why it matters at their size, and one question. Send it from a real address with an honest subject line, follow up once, and stop. Do it only when the CEO is the person who decides. At a 40-person company that is usually true. At a 4,000-person company it almost never is, and your email belongs with a direct report.
Elena sells route-planning software to pest-control companies. Her best-fit customer is a company with 8 to 20 trucks, where the owner still builds the Friday schedule by hand. This article follows how she would write to the CEO of a 40-person company in Raleigh, and what she does differently for a national chain.
Match the CEO to the size of the company
A rule of thumb, from how decisions tend to get made rather than from a study: below about 10 people the owner makes every call. From 10 to 100, the CEO still approves anything that touches revenue, hiring or a monthly bill they would notice. From 100 to 300, the CEO decides on a few strategic vendors and hands the rest to a department head. Above that, the CEO owns the whole company's direction and will not choose your scheduling tool, your payroll service or your marketing agency.
So the question is not "can I reach the CEO?" but "does this person sign off on what I sell?" If you sell something the founder personally feels, such as missed calls, empty schedules or slow payments, the CEO of a small company is right. If you sell a tool for one team inside a large company, start lower. The principle behind this is spelled out in how to find decision makers at a company.
Find the name and a deliverable address
At small companies the CEO's name is on the About page, the state business filing or the owner reply on Google reviews. At mid-size ones, check the team page, a press release or a podcast guest page. Do not write to "ceo@" unless that is the only address you can verify, because it usually lands with someone else.
For the address, look for the pattern in other staff emails on the site (first@company.com, first.last@company.com), then verify before you send. A bounce on the first email to a CEO is a bad start and a mark on your sender reputation. How to find a business owner's email address covers the steps. Rocketship's plans include a monthly allowance of contact credits for exactly this: adding a person costs 1 credit, and a verified phone and email costs 5, charged only when found.
What a CEO keeps and what they delete
An executive reads cold email on a phone between other things. Three things get an email deleted in the first two seconds: a long introduction about your company, an attachment, and a claim they have no way to check ("the leading platform"). Three things get it read to the end: a detail about their business that you could only know by looking, plain words, and a question they can answer in one line.
Avoid anything that pretends to be something else. A subject line starting with "Re:" or "Fwd:" on a first email, or "Quick question" followed by a pitch, runs against the honesty rule in the US CAN-SPAM Act and also annoys the reader. Write an accurate subject, such as "Routes at Greenline Pest," include your name, business, mailing address and a way to opt out, and honor any "no."
A four-sentence email, with a sample
Sentence one says why this person. Sentence two says who you are and what you do, in one line. Sentence three says why it matters at their size. Sentence four asks one question that is easy to answer, ideally one that lets them point you elsewhere.
Subject: Routes at Greenline Pest
Hi Tom,
I saw Greenline opened the Durham branch in April. I'm Elena, and I sell route-planning software to pest-control companies. Owners at your size tell me the same thing: the Friday schedule gets rebuilt by hand every week. Is routing something you handle yourself, or does your operations manager?

Reply "stop" and I won't write again.
Notice what is missing: no claim about saving a percentage of anything, no attached brochure, no request for a call. Ask for the call after you get an answer. If you have a real result from a customer, put it in sentence three, in plain numbers. If you do not, leave it out; an invented number is worse than none. For more on greeting choices, see the salutation for a cold email.
The assistant or chief of staff who reads it first
At companies above a few dozen people, someone else often reads the CEO's inbox. Write so that person can handle it in ten seconds. The first sentence should name something they can verify (the new branch, a news item). The last sentence should be routable: "Is this yours, or does someone else handle routing?" invites a forward. Do not ask the assistant to "get me fifteen minutes with Tom." That reads as a request for access, and it puts them in a bad spot.
Follow up once, in the same thread
Wait five to seven days, then reply to your own email. Keep it short and add one new thing:
Tom, one more note in case my first got buried. Greenline added two trucks since I wrote, so the Friday schedule probably got harder. If routing is handled, no need to reply. Otherwise, who's the right person?
That is two emails total. The mechanics of replying in the same thread are in how to send a follow-up email in the same thread. If you hear nothing after the second one, do not send a third to the CEO.
When to write to their direct report instead
Go one level down in four cases. The company is over about 200 people. What you sell serves one function (marketing, operations, IT, finance). The CEO or an assistant replied with a name. Or you have followed up once and heard nothing.
Elena's national chain has 4,000 employees. Its CEO will not choose route software. She writes to the regional operations director:
Hi Nadia, I'm writing about route planning for the Carolinas branches. I'm not sure whether that sits with you or with the branch managers. If it's yours, I have one question about how you handle schedule changes on busy days. If not, who owns it?
She does not use the CEO as a lever, and she does not say she emailed the CEO first. "I wrote to your boss" puts the director on the defensive. It is also honest to say nothing about it, since this is a different email about a different question. More on reaching the person below the top is in how to get meetings with decision makers and how to cold email the owner instead of the gatekeeper.
Four facts to keep for each CEO email
Keep four things per CEO: the date you sent, the date of the follow-up, whether a reply came from the CEO or someone else, and the name you were pointed to. A reply from an assistant saying "send to Nadia" is a win. You now have a warm introduction without having asked for one.
Writing to the right person takes time that a business owner does not always have. Rocketship finds the buyers by name, emails them from your own Gmail, follows up, and books the meeting on its own. Plans that get you customers start at $24.99 a month (Launch), and every monthly plan starts with a 7-day free trial, card required. See what the AI workers do.
