The short answer

Keep it under 80 words. Open with one specific, true thing about them (a launch, a job post, something they wrote), connect it to one problem you solve, add a single line of credibility if you have it, and end with an easy question they can answer in one word, not a request for a 30-minute call. Send it to people you've actually researched, a few a day, and follow up two or three times with something useful. Use AI to do the research and the first draft, then edit every message by hand so it sounds like you.

When I ran sales teams, we tracked reply rates on every kind of message we sent. The pattern never changed: long messages about us got ignored, and short messages about them got answers. The best reps weren't better writers. They just did five minutes of homework on each person and said one thing that proved it.

Cold outreach has a bad name because most of it is lazy. Someone pastes the same paragraph into 500 inboxes and wonders why nobody bites. You don't need to do that, and you don't need to be pushy. You need a structure, a short list of the right people, and the discipline to keep each message small.

What makes someone reply to a stranger?

Three things, in this order:

  1. It's obviously written to them. The first line could only have been sent to this person. That's what gets the rest read.
  2. It names a problem they recognize. Not your services, their problem, in words they'd use themselves.
  3. Replying is easy. A one-word answer is enough. Nobody has to open their calendar or make a decision.

Notice what's not on the list: your background, your process, your rates, or how passionate you are. All of that matters later. In a first message, it's just more words standing between them and the reply button.

What is the best structure for a cold message?

Use four short parts. Each one is a sentence, sometimes two:

  1. Notice. One specific, true thing about them: a new hire, a launch, a post they wrote, a review their customers left, a job they're advertising.
  2. Connect. Why that made you think of a problem that usually comes with it.
  3. Credibility (optional). One line on what you do or who you've done it for. Skip it if it feels like bragging.
  4. Ask. A small, low-pressure question.

Here's what that looks like for a bookkeeper writing to a small agency owner:

“Hi Sam, I saw you're hiring two more designers this quarter. Congrats. Agencies growing that fast usually find invoicing and contractor payments start eating the owner's Fridays. I take that off agency owners' plates, usually within the first month. Is that a headache for you yet, or still under control?”

That's 62 words. It proves you looked, it names a problem Sam probably has, and it ends with a question Sam can answer from a phone between meetings.

What should you never put in a cold message?

  • “I hope this message finds you well.” It tells them the rest is a template.
  • Your life story. Years of experience, certifications and your journey can wait until they're curious.
  • A list of services. One problem is a conversation. Six services is a brochure.
  • Fake familiarity. “I love what you're doing!” with nothing specific behind it reads as flattery.
  • A big ask. “Do you have 30 minutes this week?” asks a stranger for something valuable before you've earned it.
  • Attachments and links in the first message. They look like spam, and some inboxes treat them that way.
  • Anything you can't back up. If you say you noticed something, it has to be true and current.

Who should you send cold messages to?

The message matters less than who receives it. A great message to the wrong person still gets no reply. Before you write anything, get clear on two things: the kind of client you help, and a sign that tells you someone needs help right now. Those signs are called triggers, and they're the secret to cold outreach that feels timely instead of random:

  • They just posted a job for a role you could cover part time.
  • They launched something new: a program, a product, a location.
  • They raised prices, hired fast, or announced a big client.
  • They posted about being overwhelmed, behind or stuck.
  • Their reviews mention slow replies or a messy process you fix.

Build a short list of 20 to 30 people who fit and show a trigger. That's enough for a few weeks of outreach. If you haven't worked through your warm network yet, start there first, because people who already know you reply far more often than strangers do.

Should you use email or LinkedIn?

Use the channel your clients actually check. LinkedIn suits business owners, executives and corporate buyers. Connection notes have a tight character limit, so keep it to a sentence or two there. Email works when you can find a business address and have a clear, specific reason to write. Coaches and creators often answer Instagram or Facebook messages faster than email. Pick one or two channels and do them well rather than spreading thin across five.

For email, keep the subject line under six words and make it about them: “Your new design hires” beats “Partnership opportunity.” And only write to business addresses with a genuine, relevant reason to get in touch.

How many cold messages should you send?

Fewer than you think. For most solo businesses, five to ten researched messages a day, three or four days a week, keeps a pipeline healthy. That's 15 to 40 a week. Sending 200 generic messages feels productive, but you'll get fewer replies than 20 good ones and you risk your email domain and LinkedIn account being flagged.

Track three numbers each week: messages sent, replies, and calls booked. If replies are low, fix the first line. If replies are good but calls aren't happening, fix the ask and your follow-up.

How do you follow up a cold message?

Most replies come after the first message, not from it. Plan two or three follow-ups, each one giving something rather than asking: a quick idea for their situation, a useful resource, or a short story about a similar client. Space them out over three or four weeks, then close the loop politely and move on. I wrote a whole article on how to follow up when someone stops replying, with timings and what to say.

How can AI help you write cold messages?

AI is a great research assistant and a decent first-draft writer. It's a terrible final editor, because left alone it writes like everyone else. Use it in three steps. First, teach it how you write, once:

1

Teach AI your voice

Prompt

Here are three messages I've written that sound like me: [paste an email to a client, a post and a casual message]. Describe my writing style in six short rules covering tone, sentence length, words I use often, words I never use, how I open and how I close. Then rewrite this message in my style so I can check you've got it: "Hi, I hope this message finds you well. I wanted to reach out to see if you might be interested in my services."

Save those six rules and paste them into every outreach prompt. Next, let AI find the one thing worth mentioning. Paste in what's public: their website's about page, a few recent posts, a job ad.

2

Find the hook

Prompt

I help [type of client] with [result you deliver]. Here is public information about a prospect, [name], [role] at [company]: [paste website text, recent posts or a job ad]. Step 1: List three specific, recent things about them that I could mention in a first message, with where each one came from. Step 2: For each, name the problem it most likely creates that I could help with. Step 3: Tell me which one is the strongest reason to reach out now, and why. Only use facts from what I pasted. If something isn't clear, say so instead of guessing.

Then draft the message, with tight limits so it can't ramble:

3

Draft the first message

Prompt

My voice rules: [paste]. Write a first message to [name] using this structure: one sentence noticing [the hook you chose], one sentence connecting it to [the problem], one optional line about what I do, and a low-pressure question they can answer in one word. Under 80 words. No flattery, no exclamation marks, no "I hope this finds you well," no request for a call, no links. Give me two versions: one short enough for a LinkedIn connection note (under 200 characters), and one for email with a subject line under six words that's about them, not me.

Now edit. Read it out loud and cut any sentence you wouldn't say to their face. Check every fact against the source. If you can't tell whether a message was written by you or a machine, neither can they, so change something until you can.

What do you do when they reply?

Answer quickly and keep it human. If they say yes, it's a problem, suggest a short call and send your booking link with two specific times. If they say it's not a priority right now, thank them, ask if you can check back in a few months, and put a date in your tracker. If they say no, thank them and move on. A kind “no problem at all” often turns into a referral later. When the call is booked, here's how to run a discovery call that turns into a paying client.

Frequently asked questions

How long should a cold message be?

Under 80 words for email, and a sentence or two (under 200 characters) for a LinkedIn connection note. Three or four short sentences is enough: something specific about them, the problem it usually creates, an optional line about what you do, and an easy question.

What is a good first line for a cold message?

A specific, true and recent fact about the person, such as a job they posted, something they launched or a post they wrote. It proves the message was written for them, which is what gets the rest of it read. Avoid openers like “I hope this finds you well.”

Should you ask for a call in your first cold message?

Usually not. Asking a stranger for 30 minutes is a big request before you've given them a reason. Ask a small question they can answer in one word instead, such as whether the problem you named is a headache for them yet. Suggest a call once they reply.

How many cold messages should a freelancer send each week?

For most solo businesses, five to ten researched messages a day, three or four days a week, which is 15 to 40 a week. A smaller number of well-researched messages gets more replies than hundreds of generic ones and keeps your email and LinkedIn accounts in good standing.

How many times should you follow up a cold message?

Two or three times over three to four weeks, each time offering something useful such as an idea, a resource or a short client story, then send a polite closing message and move on.

Is it okay to use AI to write cold emails?

Yes, as long as you use it for research and first drafts and then edit by hand. Give it your own writing rules so it sounds like you, only let it use facts you've checked, and read every message out loud before you send it.
