I built five free outbound calculators from eight years of our own campaign data

I run outbound programmes for a living and got tired of every benchmark online being a vendor survey or a number someone invented in 2019 and everyone has recycled since.

So we published ours: 389,890 prospects, 15,018 meetings, 41 client programmes between 2018 and 2026, and fifteen controlled A/B tests where prospects were split at random inside each account so industry, geography, seniority and company size stay constant on both sides.

Then I built five calculators on top of it. No signup, no email, nothing stored, everything runs in your browser:

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.
Message generator. Builds a first message in the format that replied at 44.5%: two and a half sentences, question-led, 240 to 420 characters, no pitch.
Voice note script generator. 25 to 40 seconds with timing marks.
ROI calculator. Meetings, pipeline, cost per meeting, payback.

Three findings that surprised me most, in case you never click:

Targeting beat copy by a mile. The same sequence got 13.0% replies on a job-title list and 51.9% on a list where we'd verified per person that the problem was actually theirs.

Answering a reply within 24 hours converted at 21.4%. After 48 hours, 3.6%.

Seniority buys a reply, not a meeting. Directors replied more and booked half as many meetings as the level below them.

Disclosure: I run Prospectio, which is a LinkedIn and email outreach tool. The data and the calculators are free and ungated, and you can use any of it without touching the product.
