First prospecting message: 15 examples based on a buying signal

What makes a good first prospecting message?

A good first message is 2 to 4 sentences long and does 3 things: it names the signal you spotted, links it to what you do, and asks one easy question. Nothing else. The reader should understand in 5 seconds why you are writing to them, and why now.

The signal does the heavy lifting. Someone who just commented on a post, posted a job ad or registered for a trade show has a topic on their mind. Your message is about that topic, not about you. If you need a refresher on what counts as a signal, start with our guide to B2B buying signals, with examples.

What structure should your opening line follow?

Use the same 3-step order every time. It works on LinkedIn, by email and on WhatsApp.

1. The signal you saw. One factual sentence: “Saw your comment about…”, “I noticed you're hiring a…”. Quote a specific detail. It proves you actually read it.
2. The link to what you do. One plain sentence tying the signal to a concrete result for them. No company introduction.
3. One easy question. Something they can answer in a line without committing to anything. It's about their situation, not about a call.

Here is the example we use on our own site. The signal: a business owner comments “We're looking for local suppliers, import lead times are killing us.” The message:

Saw your comment about import lead times: if a regional supplier could deliver within 72 hours, what would that change for you?

One sentence. The signal is quoted, the benefit has a number on it (72 hours), and the question gets them talking about their own problem. That's the template to copy.

How long should a first cold message be?

2 to 4 sentences, roughly 30 to 70 words. Any longer and it reads like a mass send, so people skim it. Any shorter and you tend to drop the link between the signal and your business, and the question falls flat.

Quick test: read it out loud. If it takes more than 15 seconds, cut. Remove the sentences about your company first, then the adjectives.

What kills replies in a first message?

5 mistakes sink reply rates, even when the signal is strong.

• The pitch. Describing your offer, your clients, your numbers. They didn't ask. Save it for when they reply.
• The attachment. A PDF brochure in a first message looks like advertising, and plenty of people won't open a file from a stranger.
• “I hope this email finds you well” / “I'm reaching out because…”. Empty openers that signal a sales message. Start with the signal instead.
• The booking link. Asking a stranger for 30 minutes is too early. Ask a question; the meeting comes later.
• Generic flattery. “Love your inspiring journey” proves nothing. A compliment only counts if it mentions a specific fact.

15 first message examples based on a buying signal

The signals below are made-up examples built to illustrate each case. The companies and people don't exist. Swap the brackets for your own details.

Signal: a comment on a post

1. The import lead times comment

• The signal (made-up example): the owner of a small manufacturer comments on a post: “We're looking for local suppliers, import lead times are killing us.”
• The message: “Saw your comment about import lead times: if a regional supplier could deliver within 72 hours, what would that change for you?”
• Why it works: it reuses their words, puts a number on the benefit and asks an open question about their situation.

2. The late invoices comment

• The signal (made-up example): an agency owner comments: “I spend every Friday chasing unpaid invoices.”
• The message: “You mentioned spending Fridays chasing invoices. Roughly how many are overdue right now?”
• Why it works: the question is concrete and can be answered with a number. It opens the conversation without selling anything.

3. The comment that asks a question

• The signal (made-up example): a sales director asks under a post: “Anyone have feedback on e-signatures for quotes?”
• The message: “You were asking about e-signatures for quotes. Is the sticking point the tool itself, or clients not signing?”
• Why it works: they asked a public question. You answer with a question that helps them pin down what they need.

Signal: a job ad

4. The sales job ad

• The signal (made-up example): a services company posts a job for a “field sales rep, South West region”.
• The message: “Saw you're hiring a field sales rep for the South West. Until they're on board, how are you keeping the diary full?”
• Why it works: hiring shows a growth goal. The message targets the gap between today and the new hire's start date.

5. The admin job ad

• The signal (made-up example): an accounting firm is hiring an “admin assistant to process supplier invoices”.
• The message: “Your ad mentions processing supplier invoices. Roughly how many do you handle a month?”
• Why it works: the job ad describes a task. Your question sizes the volume, which quickly tells you if your solution fits.

Signal: a new office or a new site

6. The office move

• The signal (made-up example): a company posts: “We're moving into our new Manchester office next month.”
• The message: “Congrats on the new Manchester office. Are phones and network already sorted, or still in progress?”
• Why it works: a move creates a to-do list. The question offers 2 simple answers.

7. The second branch

• The signal (made-up example): an estate agency announces a second branch in Bristol.
• The message: “Saw you're opening in Bristol. To get known in the area, are you leaning towards local or online?”
• Why it works: the signal says “we need to fill this new location”. You help them think out loud.

Signal: a trade show

8. The exhibitor

• The signal (made-up example): a small company appears on the exhibitor list of a trade show in its sector.
• The message: “I see you're exhibiting at [show] in March. Have you worked out how you'll follow up the contacts from the stand?”
• Why it works: exhibitors pay to generate contacts. The question hits the moment many contacts get lost: after the show.

9. The visitor who says so

• The signal (made-up example): a buyer posts: “I'll be at [show] on Thursday, looking for lighter packaging options.”
• The message: “You're after lighter packaging at Thursday's show. Is the main goal shipping costs, or weight for your customers?”
• Why it works: they said what they're looking for. The message reuses it and asks them to narrow it down, which sets up a meeting on the day.

Signal: a new role

10. The new director

• The signal (made-up example): someone announces they've started as head of operations at a retail chain.
• The message: “Congrats on the new operations role. In your first 90 days, which project do you want to tackle first?”
• Why it works: new managers often review tools and suppliers. The question lets them name their priority.

11. The new owner

• The signal (made-up example): a business owner writes that they've just bought a 15-person company and want to “review everything”.
• The message: “You mentioned reviewing everything after the takeover. On [your topic], are you starting from scratch or keeping what's there for now?”
• Why it works: a new owner makes lots of decisions quickly. A simple either/or question takes 5 seconds to answer.

Signal: a “looking for a supplier” post

12. The public request

• The signal (made-up example): a business owner posts: “Looking for someone to rebuild our website, tight budget, needs to be live before summer.”
• The message: “Saw your post about rebuilding the site before summer. If you had to choose, which matters more: the deadline or the budget?”
• Why it works: they've already described the need. You don't repeat your offer, you help them rank their criteria.

13. The request for a recommendation

• The signal (made-up example): in a business group, a founder asks: “Can anyone recommend a payroll provider? We're about to hit 20 staff.”
• The message: “You were looking for payroll help as you hit 20 staff. What's the bigger headache today: the time it takes or the mistakes?”
• Why it works: quoting the 20-staff detail shows you read it. The question gets to the real problem.

Signal: a new line of business or a new offer

14. The new activity

• The signal (made-up example): a building firm adds energy-efficiency retrofits to its activities, visible in a public company filing.
• The message: “I noticed you've added energy-efficiency retrofits. Do you already have your first jobs lined up, or are you still looking for the first clients?”
• Why it works: a new activity means new needs: clients, tools, training. The question shows where they are.

15. The new offer

• The signal (made-up example): a consultancy announces a new service for small manufacturers.
• The message: “Saw the launch of your service for small manufacturers. Are you mainly selling it to your existing network or to new clients?”
• Why it works: a launch creates a need for visibility. The question shows you get the challenge without spelling it out for them.

Notice what they have in common: none of these 15 lines introduces the seller. The link to your business shows up in the choice of question, not in a description of your offer.

How should you adapt the message to each channel?

The structure stays the same. Only the format and length change.

LinkedIn. The signal often started there, so the context is clear to the reader. For the full method and the limits to respect, see our signal-based LinkedIn prospecting method.

Email. Rules differ by country. In France, the data protection authority (CNIL) says B2B email prospecting is allowed when the message relates to the recipient's job, and the person must be able to opt out easily (CNIL guidance, in French). In the UK and US, check your local rules. In practice: a message tied to their role, a clear sender identity, and a line such as “If this isn't relevant, just say so and I won't write again.” This is not legal advice.

WhatsApp. Only use it if the number is a business number made public by the person or company (website, email signature, business page), and the context is clear. Keep it very short and polite, and stop at the first “no thanks”. Example:

Hi, Julian from [company], I found your number on your website. Saw your post about delivery times: are you still looking for a haulier for the North West?

Should you follow up, and how?

Yes, once, 4 to 7 days after the first message, and with something new. A follow-up that just says “Did you see my message?” adds nothing. Add a useful detail or make replying even easier.

• Follow-up with a yes/no question: “Coming back to the import lead times. A simple yes or no is fine: is it a priority for you this quarter?”
• Follow-up with something useful: “About your field sales role: I have a list of 5 interview questions our clients use for this kind of hire. Want me to send it?”
• Follow-up that offers a way out: “I don't want to clutter your inbox. If payroll is sorted, let me know and I'll leave it there.”

If there's still no reply after that, stop. Note the contact and wait for a new signal. A new signal gives you a real reason to write again weeks later, without pushing.

Bad message vs good message: what's the actual difference?

How do you write these messages quickly, every week?

Build a set of 5 templates, one for each type of signal you see most often. For each new lead, keep the structure and only change the signal detail and the question.

1. Write down the signal word for word, with the date.
2. Pick the template for that type of signal.
3. Swap in the quoted detail and adjust the question to your business.
4. Check: 4 sentences max, no pitch, one question.
5. Set a follow-up date 4 to 7 days later.

The slow part is still finding the signals. If you don't have time for that, our guide to finding B2B clients when you have no time to prospect walks through the options.
