Free outbound tools
Five tools built on the same dataset as our benchmarks: 389,890 prospects, 15,018 meetings, 41 client programmes. No sign-up, no email, nothing stored. Everything runs in your browser.
Most free sales calculators are lead-capture forms with arithmetic attached, and the rates they apply were invented by whoever built the page. These use measured rates from campaigns we ran and can defend line by line, and where a number is an estimate rather than a measurement we say so on the page.
The two worth starting with are the reply rate calculator if you already have a campaign running, and the ICP fit scorer if you do not. Targeting explained more of the variance in our tests than any copy decision, so it is the cheaper place to look first.
LinkedIn message generator
Three first messages in the format that replied at 44.5 percent: two and a half sentences, question-led, 240 to 420 characters, no pitch.
Reply rate calculator
Enter your sends, replies and meetings. Get the benchmark for your exact persona, company size and region, plus the fixes ranked by measured effect.
ICP fit scorer
Score a segment out of 100 before you build the list, with expected reply rate, meeting rate and deal size.
Voice note script generator
A 25 to 40 second script with timing marks and delivery notes. Voice at step two lifted meetings from 4.1 to 5.0 percent.
Outbound ROI calculator
Meetings, pipeline, closed revenue, cost per meeting and payback, using measured rates rather than an assumption.
Where the numbers come from
Every rate in these tools comes from 41 live client programmes across 17 clients between 2018 and 2026, measured to the point a meeting was accepted in the client's calendar. Prospects were split at random inside each account so industry, geography, seniority and company size are held constant on both sides of every test, and no test was called below 2,000 prospects per arm.
The full method, all fifteen controlled tests and the breakdowns by persona, company size and region are published on the 2026 outbound benchmarks page, free and without a form.
