Every page is also served as markdown at its URL plus .md. A prospecting plan in two computations: how many accounts are worth working, and how much pipeline a quarterly target needs. Labeled example inputs. Prospecting is finding and contacting people who could buy before they ask. Plans for it tend to be either vague or a pile of activity targets, so this post builds one from two calculations: the size of the market you can work, and the pipeline your target requires. The company is fictional (Ledgerlane, selling accounts-payable software), and its inputs are examples for illustration, not benchmarks. ## Start from the profile, not the list A prospecting list is only as good as the profile behind it. Write down the industries, company sizes, geographies and roles that match your best deals so far, plus the signals that suggest a need. If you have no deals yet, use the problems you solve and the people who feel them. Our glossary entries on the ideal customer profile and total addressable market define both terms. ## Step one: how many accounts are worth working For a United States market, the Census Bureau publishes County Business Patterns, an annual series of establishment counts by industry, employment size and geography. It covers establishments with paid employees and excludes some industries, so check the coverage notes on the About page before you rely on a figure. Say a lookup for Ledgerlane's industry and region returns 2,400 establishments (an invented input). Ledgerlane's software suits 40% of them, it expects to win 5% of those, and a customer is worth $18,000 a year. The market size function returns the figures below. Example market size for Ledgerlane (inputs invented for illustration) | Layer | Companies | Yearly value | | --- | --- | --- | | Total market | 2,400 | $43.2 million | | Serviceable market (40% fit) | 960 | $17.28 million | | Obtainable market (5% win share) | 48 | $864,000 | ## Step two: how much pipeline the target needs Ledgerlane wants $600,000 of new business this quarter. At a 25% win rate by value, the pipeline needed is 4 times the target, or $2,400,000. The pipeline coverage function compares that with what is already open. Example pipeline coverage for a quarterly target of $600,000 at a 25% win rate (inputs invented) | Scenario | Open pipeline | Coverage | Pipeline needed | Gap | New opportunities of $18,000 to close the gap | | --- | --- | --- | --- | --- | --- | | Pipeline already open: well covered | $2,400,000 | 4 times | $2,400,000 | $0 | 0 | | Pipeline already open: thin | $900,000 | 1.5 times | $2,400,000 | $1,500,000 | 84 | ## Turn the gap into daily work In the thin scenario Ledgerlane needs 84 new opportunities this quarter. Divide by your own rates, working backwards: opportunities from meetings held, meetings held from meetings booked, meetings booked from replies, replies from delivered messages. The steps are the same ones in our lead generation guide, and the pipeline coverage calculator does the first division for you. Then check the result against capacity. If the number of contacts it implies is more than your team can reach with care, the choices are a longer timeline, a higher deal value, a better win rate, or more people. Writing the constraint down early beats discovering it in week ten. ## Rules to build in from the start These are the points we checked at the sources below on 2026-10-19. - The FTC says CAN-SPAM applies to business-to-business email, requires a physical postal address and a working way to opt out, and sets penalties of up to $53,088 for each separate violating email. - Google asks senders of more than 5,000 messages a day to Gmail to authenticate with SPF, DKIM and DMARC and keep the reported spam rate below 0.30%. - The FTC question and answer page says most calls to a business to solicit sales from that business are exempt from the Do Not Call provisions, and also points to separate FCC rules. ## Where ColdMeetings fits ColdMeetings is software plus an API: domains and DNS records, mailboxes, list import and verification, sequences, replies, meeting booking and a compliance layer. It runs the email part of a prospecting plan. You still choose the profile, write the message and take the meetings, and nothing here guarantees a result. ## Questions ### How big should a prospect list be? Size it from your target: compute the pipeline needed, then the opportunities, meetings and contacts that implies at your own rates. The example above shows the first steps. ## Where to go next - [Pipeline coverage calculator](https://coldmeetings.com/tools/pipeline-coverage.md) - [Market size calculator](https://coldmeetings.com/tools/market-size.md) - [Ideal customer profile, defined](https://coldmeetings.com/glossary/ideal-customer-profile.md) - [Total addressable market, defined](https://coldmeetings.com/glossary/total-addressable-market.md) ## Sources - [US Census Bureau: County Business Patterns](https://www.census.gov/programs-surveys/cbp.html), read 2026-10-19 - [US Census Bureau: About County Business Patterns](https://www.census.gov/programs-surveys/cbp/about.html), read 2026-10-19 - [FTC: CAN-SPAM Act, a compliance guide for business](https://www.ftc.gov/business-guidance/resources/can-spam-act-compliance-guide-business), read 2026-10-19 - [Google: Email sender guidelines](https://support.google.com/a/answer/81126), read 2026-10-19 - [FTC: Q&A for telemarketers and sellers about the Do Not Call provisions of the Telemarketing Sales Rule](https://www.ftc.gov/business-guidance/resources/qa-telemarketers-sellers-about-dnc-provisions-tsr), read 2026-10-19 ## Related - [Lead generation explained with a funnel](https://coldmeetings.com/blog/what-is-lead-generation.md) - [B2B lead generation channels, compared](https://coldmeetings.com/blog/b2b-lead-generation-channels.md) - [Demand generation and its pipeline math](https://coldmeetings.com/blog/demand-generation.md)
