How to write the first message to a B2B prospect

A proven structure for a first B2B email or message: subject line, reason for reaching out, relevance and a small ask. With illustrative examples and mistakes to avoid.

Most first sales messages get deleted in two seconds, and almost always for the same reason: they talk about the sender, not the reader. This guide explains the structure of a first B2B message that actually gets replies, with illustrative examples and the most common mistakes.

Why first messages fail

  • Generic: they could go to any company by swapping the name. Readers notice instantly.
  • Self-centered: three paragraphs about “us” and none about the recipient.
  • No reason: they never explain why you are writing to this company right now.
  • They ask for too much: a one-hour meeting with someone who has never heard of you.

The anatomy of a first message that works

1. Subject line: specific, no fluff

Not “Partnership proposal” or “Business opportunity”. What works is the real topic of the message in a few words (“Idea for your new Riverside warehouse”, “Question about your packaging line”).

2. First sentence: the reason for reaching out

The most important sentence in the message. It proves you did your homework: mention something real and recent about their company — an expansion, a job posting, a news story, something on their website. It is the difference between “I got scraped into a list” and “this person knows who we are”.

3. The bridge: why that brings you in

Connect their situation to the problem you solve, in one or two sentences and in their language, not yours. No service lists, no credentials: just the link between what is happening to them and what you do.

4. The close: one small ask

Do not ask for an hour: ask for 15 minutes, or simply for a reply (“worth a quick note on how we would approach it?”). The smaller the commitment, the easier the yes.

Illustrative example

Subject: Your expansion at the Cove industrial park

Hi Maria, I saw you are expanding your facilities at the Cove — congratulations. We work with warehouses your size at exactly that stage: when space grows and stock control starts falling behind. Worth 15 minutes to show you how we solved it in a similar case? If you are not the right person, I would appreciate a redirect.

Best, [name and company]

Invented example for illustration purposes. Note the mechanics: real reason → bridge to the problem → small ask → graceful exit. Under 90 words.

Mistakes that cancel everything else

  • Attaching catalogs or decks to a first contact: nobody opens them and they trip spam filters.
  • Lying or overclaiming (“we are the leaders”, “guaranteed results”): trust is destroyed before it starts.
  • Pressuring (“when can we call you today?”): a first message opens a door, it does not close a sale.
  • No follow-up: many replies come on the second or third touch; giving up after one wastes the work done.

The message only works with the right recipient

An excellent message to the wrong company is still a wasted message. Half the result lies in choosing who you write to: companies that fit what you sell, with some reason to buy now. That is what our guide on finding potential customers in your area is about.

Frequently asked questions

How long should a first prospecting email be?

Between 60 and 120 words. It should be readable in full in a phone preview. If you need more space to explain yourself, the message is trying to do too much.

How many follow-ups are reasonable?

Two or three, spaced several days apart, each adding something new (a fact, an example, a different angle). If there is still no reply, leave the door open and come back in a few months with a fresh reason.

Is email, phone or LinkedIn better?

It depends on your industry and the person. Email lets people think and forward; phone accelerates in direct-dealing sectors; LinkedIn works with profiles active on the network. What matters is the content of the message, not the channel: the same empty text fails on all three.

Can I use templates?

As a structure, yes; as final copy, no. A template gives you the skeleton (reason, relevance, small ask), but the reason for reaching out and the reference to their company must be real and specific to each recipient.
