Is your market big enough for cold outreach?
Do the napkin math: how many emails one customer takes, what that costs, and whether your market has enough people.
Cold outreach works best when two things are true: a customer is worth a lot to you, and there are enough of them to email. You can check both in half an hour.
Many outbound teams look for a market of around 100,000 reachable people and customers worth $10,000 or more. Those are guides, not rules. The napkin math below gives you your own answer.
Step 1: Write down what one customer is worth
Use the money you'd expect over their whole time with you, not the first invoice. A customer paying $300 a month for two years is worth $7,200.
Step 2: Guess your funnel, honestly
Fill in these four steps with your best guess. You'll replace them after your first test.
| Step | Example guess | Your guess |
|---|---|---|
| Emails that get a positive reply | 1 in 100 | |
| Positive replies that become a call | 1 in 3 | |
| Calls that become a customer | 1 in 4 | |
| Emails per customer | 100 × 3 × 4 = 1,200 |
Step 3: Work out what a customer costs to win
Multiply emails per customer by what each email costs. Data is a few cents. Sending tools and your time are most of the rest, so count those honestly.
A common aim is for a customer to be worth at least three times what they cost to win, and ten times is excellent.
Step 4: Count the people you can reach
Search for your buyer in ContactYard and read the total. It's free, and it counts people with an email on file.
Step 5: Divide the market by emails per customer
This tells you roughly how many customers the market can give you in a first pass.
Fictional example
- Market (reachable people)
- 12,000
- Emails per customer
- 1,200
- Customers from one pass
- 10
- Customer value
- $7,200
- Revenue from one pass
- $72,000
Ten customers might be enough to build on, or far too few. That depends on your costs and goals. The point is that you now know.
What if the number is too small?
- Widen the market. Add nearby titles or sizes, then check the quality of what comes in.
- Raise the value. Sell a larger package to the same people.
- Contact again later. You can email the same market every few months with a new angle.
- Use another channel. Small markets suit referrals and partnerships better.
Tip: Your guesses will be wrong. That's fine. A 500-email test replaces them with real numbers.
