Guide

How to write a first email to a business you don't know.

The emails that get answered are short, specific and about the reader. Here is a four-part structure that works for almost any business, with examples.

About 5 minutes to read. Updated September 2026.

The four parts

  1. One true fact about themSomething real from their website or news: they added Saturday hours, they are hiring, their gala is in April. It shows you looked, and it is the reason for writing.
  2. A picture of the winOne sentence on what would be better for them. Not your features: their Monday morning, their tax season, their event running smoothly.
  3. Who you are and what they getYour name, your business, and what you do for businesses like theirs, in one or two sentences.
  4. One easy questionGive them two small options, such as a trial or a quote, a call or a one-page overview. Either answer moves things forward.

An example

Here is the structure in a real-looking email from a cleaning company to a dental practice. The names are made up.

Example emailFrom Luis, Clearview Commercial CleaningTo Priya Shah, Practice Manager, Lakeside Family DentalSubject Mondays after your Saturday hours

Hi Priya,

Lakeside is open on Saturdays now.

Picture Monday mornings starting with every operatory already cleaned and restocked after the weekend, without anyone on your staff staying late.

I'm Luis with Clearview Commercial Cleaning. We clean dental and medical offices after hours, with the same two-person crew each visit so they learn your space.

Would a free walkthrough next week work, or would a written quote be easier?

Luis

It is under 100 words. Every sentence is about Priya's practice or a direct answer to "who is this and what do they want."

Subject lines

Keep the subject short, plain and specific to them: "Printing for the spring gala," "Before busy season," "Lunch for the Friday team meeting?" It should read like a note from a person, and it must honestly reflect what the email is about.

Avoid all caps, exclamation marks, "quick question" and anything that pretends to be a reply or a previous conversation.

What to leave out

The follow-up

If there is no answer after three or four working days, send one short follow-up in the same thread. Add something new: a sample, a price, a relevant detail. Then stop. If someone replies to say no, or asks you to stop, stop for good.

The rules every email has to follow

In the United States, emails to businesses fall under the CAN-SPAM Act. At minimum: say who you are, use an honest subject line, include your real postal address, and give people a clear way to opt out that you honor quickly. Our guide to cold email and the law covers the details.

DemandSwarm writes every email in this four-part structure, from what each business's own website says, and checks that every fact is real before it goes out.
Questions

Quick answers.

How long should a cold email to a business be?

Short enough to read in under 30 seconds, usually under 120 words. Four parts: a true fact about them, the win, who you are, and one easy question.

Should I include a link to my website?

In a first email to someone who does not know you, usually not. Links add little and can hurt delivery. Offer to send more, and include it when they reply.

Should I mention price in the first email?

Usually not. Price lands better once someone is interested. The exception is when a low, simple price is the main reason to reply.
