Drop a live, interactive ROI calculator into any cold email as a single link. Your prospect drags their own numbers — team size, deal value, current reply rate — and watches their own upside compute in real time. A PDF one-pager makes your claim; a LiveProof link makes them prove it to themselves.

It's Folderly's median relative deliverability lift across audited senders, used here as an illustrative default for the demo. In the product you set your own assumption per link — the calculator is yours to model, not a fixed claim.
Folderly is the B2B email-deliverability product I run. LiveProof is the cold-email-native member of the same wave — and the deliverability layer (so your link lands in the inbox, not spam) is built in. The co-brand is pending Folderly leadership sign-off.
Every time a prospect drags a slider, LiveProof records it against that link — who opened it, which inputs they moved, and the upside they computed. You see a ranked list of warm hand-raisers in your dashboard. No form to fill out before they engage.
Yes — it's a single hosted page, no plugin or download. It renders live on desktop and mobile. Deliverability is handled by Folderly so the email carrying the link reaches the inbox in the first place.
$39/month, flat, unlimited calculator links. 14-day refund. Or join the LiveProof beta and we'll send you a sample link plus the lead-capture spec.
