Cold Outreach: A Plan for Your First 100 Prospects

Cold outreach is the first contact you make with a business that has never heard of you, by letter, email, LinkedIn or phone. For an agency it works best as a small, planned campaign. This guide gives a plan for your first 100 prospects. It covers who to pick, what to send on which day and what to expect.

What is cold outreach?

Cold outreach is contacting someone who has no relationship with you, to start a conversation. "Cold" describes the relationship. It says nothing about the tone.

Job seekers use the term too, for writing to people they would like to work with. The idea is the same. This guide is about selling.

Four channels carry most of it.

The letter sits in a less crowded place than email. In the ANA's Response Rate Report 2021, 38% of the marketers surveyed used direct mail and 82% used email (ANA). That survey spans several industries and is a few years old, so take it as direction.

What cold outreach strategy fits an agency?

A cold outreach strategy is three decisions, made before anything goes out.

1. Who. Businesses whose websites show a problem you can fix.
2. What you say. One finding from their own site, in the first line.
3. In what order. A letter first, then email, then LinkedIn.

The first decision carries the most weight. We scored 20,000 Dutch company websites and sent 3,570 cold emails to three groups. The businesses with the weakest 20% of sites replied positively about 3.2 times as often as a random sample of the rest. The full test is in our write-up.

An agency has an advantage here that most sellers lack. The need is visible before you write. Open the website and you know whether there is a reason to get in touch.

How do you choose the first 100 prospects?

Look at 500 businesses in one trade and keep the 100 with the weakest websites.

The ratio comes from our study, where the prospects were the 20% of websites with the most problems. 100 is 20% of 500.

1. Pick one trade in one area. Roofers in Tulsa County, or dentists across the Phoenix metro. If the area holds fewer than 500, widen the area before you add a second trade.
2. Collect the 500. For each one you need the business name, the owner's name, a postal address, an email address and the website.
3. Check each website. Our list of nine signs a business needs a new site gives you the checks.
4. Keep the weakest 100. Write down one finding for each, in a sentence the owner could verify in ten seconds.

By hand, step 3 is the slow part. Our October 2026 study estimates a manual review at about 8 minutes a site. At that pace, 500 sites take 4,000 minutes, or about 67 hours.

There are two ways to cut that down. Start with one batch of 25, which means 125 sites and about 17 hours. Or let software do the scoring. Leadodo's AI, Twip, scores every website in a search out of 100 across 10 domains, and sites that score below 40 form the shortlist. See how the score works.

What does the 40-day plan look like?

Four batches of 25 start 7 working days apart, and each batch follows the same sequence. Every day in this plan is a working day, and the last step of the last batch falls on day 40.

The sequence is the one your Outbound Machine runs in Leadodo. Six steps over 19 working days. A posted letter arrives on day 1, emails follow on days 4, 7 and 11, and LinkedIn on days 15 and 19. Day 15 is a connection request with a message. When the person accepts, a second message follows.

Weekends are not counted, so no step falls on one. On the calendar, 40 working days are 8 weeks.

Batches beat one big send for three reasons. You can answer every reply the same day. You learn from batch 1 before batch 4 goes out. And your email volume stays low. The busiest days are 11, 18 and 25, when one batch's third email and the next batch's first fall together. That is 50 emails.

Here is the whole plan in totals. At most you would send 100 letters, 300 emails and 200 LinkedIn steps, which is 600 contacts. In practice it is fewer. The sequence stops for a business the moment it replies, and the second LinkedIn message follows when the person accepts the request. Through your Outbound Machine, a posted letter in the US costs about 86 cents, for one page in black and white, sent First Class. That covers printing, postage and the envelope, so 100 letters come to about $86.

Two rules hold throughout. A reply stops the sequence. A no ends it on every channel. Review is your choice. You can review every letter and message before it goes, review a sample such as the first 100, or let your Outbound Machine send without review. For a first campaign, our advice is to read them all. Our guide to the sales cadence explains why each step sits on its day.

Cold outreach examples for each channel

Each example names the business, states one finding the owner can check and asks for one small thing. The roofer below, Redline Roofing at redlineroofing.example, is made up, and so is the phone number.

The letter, day 1.

Dear Mr. Carter,

I looked up Redline Roofing on my phone on Monday, the way a homeowner with a leak would. The "Free estimate" form would not send. I tried twice.

Storm season is when that form matters most. Right now it turns people away.

I build websites for trades in Tulsa, and I'd like to show you the fix and two other changes. You can reach me on 555-0117. I'll also email you early next week.

The email, day 4.

Subject: My letter about Redline's estimate form

Hi Mr. Carter,

A letter from me should have reached you a few days ago. It was about the "Free estimate" form on redlineroofing.example, which does not send from a phone.

I recorded 90 seconds of it failing. May I send you the video?

[Your name, studio name and postal address]

Reply "stop" and I won't write again.

The message with the LinkedIn connection request, day 15.

Mr. Carter, I wrote to you about the estimate form on Redline's site. I won't pitch here. I'd be glad to connect in case the website comes up later this year.

The letter does the explaining. The email makes replying easy. The LinkedIn message only puts a face to the name. Our guide to why the letter goes first covers the letter in full.

What should you expect from 100 prospects?

About two positive replies, if your results matched our test. They may not, and nobody can promise you a number.

Here are the three groups from our October 2026 email test, with the arithmetic for 100 prospects.

Read those figures with their limits. The test covered Dutch companies. It tested email only, so it says nothing about letters or LinkedIn. And the gap between the last two rows was not statistically significant (p = 0.238). We cannot tell you what the letter adds, and we will not guess.

So treat the first 100 as a test of your list and your message. A client from it is a bonus.

What do you do after the first 100?

Count five things, then change one.

Be careful with small differences. In our test, 3,570 emails were not enough to show that the specific email beat the generic one. With 100 prospects, two replies against three tells you nothing about wording. Change one large thing for the next 100, such as the trade or the area.

When a business does reply, answer the same day and offer two times for a short call. Our guide to appointment setting covers that step, and outbound sales covers the wider process.

Questions

Is cold outreach legal in the US?

For email, yes, when each message meets the CAN-SPAM Act. The FTC's guide asks for a valid postal address and a way to opt out, honored within 10 business days, and it makes no exception for email sent to businesses (FTC). Calls and texts have their own rules, which this guide does not cover. This is not legal advice.

How many times should you contact a cold prospect?

Up to six times over 19 working days in this plan. That is one letter, three emails and two LinkedIn steps. Stop the moment the business replies, and stop for good when the answer is no.

Does cold outreach still work?

It works when the list is right, and at modest rates. In our test, businesses with the weakest websites replied positively about 3.2 times as often as a random sample of the rest. Even then, the best group replied positively 2.35% of the time. Plan for steady, small numbers.

What is the difference between cold outreach and warm outreach?

Cold outreach goes to someone with no prior contact with you. Warm outreach goes to someone who knows you, such as a referral, a past client or a business that has replied. One reply turns a cold prospect into a warm one, and from there a person takes over.

How long does cold outreach take to show results?

One full sequence takes 19 working days. The plan on this page reaches 100 prospects in 40 working days, which is 8 weeks. Judge the list after that, because replies can follow any of the six steps.
