Size a pilot worth running

Three numbers make the pilot useful

Start with the market you can reach, the conversations you can handle and the cost of doing the work properly. Those three numbers give the pilot a useful shape. Two tempting shortcuts, a spare budget and a hoped-for meeting count, are worth checking against them before you commit.

A good pilot buys a decision. You should finish it knowing whether this audience responds to this offer and whether the resulting conversations deserve another run. Agree what would make that decision clear before you build the list.

One: know the size of the opportunity

Count companies that fit the offer, then inspect the records. Check the actual business and buyer behind each match. That gives you a market you can plan around and a better starting point for the research.

Imagine four thousand suitable companies, then four hundred. The smaller market gives you less room to learn through sending, so the first approach needs more preparation. With either size, treat a company's attention as something you want to earn and keep.

For a capacity example, take a daily ceiling of 15 cold emails per Google mailbox and 3 per Microsoft mailbox. A three-email sequence uses three sends per contact: five new contacts a day from one Google mailbox, or a hundred from twenty. Actual capacity depends on readiness, warmup and follow-ups due, so check those before using the example to plan a launch.

Two: make room for the conversations

Put someone behind the replies. We answer positive replies within thirty minutes during UK working hours, then hand qualified conversations over with the context. Your team owns the call and the close, which makes its available time part of the pilot's design.

Start with the diary. A founder who can take four useful conversations a week should plan around four; hoping to manage eight later creates work the business may struggle to use. Leave room for the follow-up that makes the initial interest valuable.

Your pilot should establish how your market responds to your offer. Track replies, interested buyers and qualified conversations separately, then use those results to decide what deserves a larger run. The useful figure is the one that helps you make your next decision.

Three: fund the work behind the reply

Delivery has a setup cost and a cost that grows with the accounts you approach. Give both room in the plan so you know what the pilot is paying for and what a larger run would involve.

Our earlier setup allowed at least twenty-one days for domain and mailbox preparation. Readiness is now checked against the current operation, and warmup keeps running alongside cold sending. A fortnight of campaign activity still needs the preparation in front of it, so plan that time into the engagement.

The work includes finding the right audience, writing the campaign, preparing the sending setup and handling replies. Doubling the account count changes the data and sending capacity you need. Scope the preparation and the inbox coverage together.

The in-house comparison is 35 to 45 thousand pounds in SDR salary, about 60 thousand in the first year including ramp and tooling. A pilot gives you evidence about the market before deciding how much permanent capacity to build around it.

Give the test its full calendar

With emails on days 0, 3 and 8, a contact added on the final sending day still has follow-ups ahead. Give the campaign a fortnight after its last sequence finishes to collect and assess later replies. The test should include the whole conversation window.

Track preparation and live sending separately. That lets you explain both the time needed to launch and the time the offer spent in front of buyers. Each answers a different planning question.

Keep the list fresh while the setup is prepared. At 2 to 3% monthly data decay, an eight-week wait can leave roughly 4 to 6% of the file needing another look. Recheck close to sending so the research reaches someone who still owns the job.

Build the plan in this order

1. Count the companies that fit the offer and record the market before setting volume.
2. Decide how many conversations your team can handle alongside its existing work.
3. Allow for preparation, sending and the reply window after the final sequence.
4. Use those three to set the sending plan.

Write down the result and review date that would justify continuing, changing direction or stopping. Then the pilot ends with a decision you can make together, backed by what the market actually did.
