Build the result

List cost is not the price of raw leads. It is the price of usable leads after verification, invalids, catch-alls, and policy decisions.

Lead countRaw records planned for verification before dedupe, suppression, and policy filtering.Monthly list volumeUsed to estimate recurring spend and decide whether tiered vendor pricing matters.Expected invalid rateEnter a percentage. The estimator should clamp rates from 0 to 100 and show the assumption clearly.Expected catch-all rateEnter a percentage for risky or unverifiable addresses that may still accept mail.Expected duplicate or suppressed rateOptional quality assumption for records removed before or after verification.Raw lead cost per recordOptional. Enables all-in cost per usable lead instead of verification-only cost.Verification policyControls which addresses count as usable and which should be suppressed or segmented.Catch-all risk toleranceUsed for the recommendation, not as a promise that catch-all addresses are safe.Vendor pricing assumptionsPricing is user-maintained. The product should avoid claiming live vendor prices unless an admin-maintained source exists.Comparison modeKeeps the UI clear when the user has one vendor, several vendors, or no confirmed pricing.Sensitivity rangeControls the invalid-rate scenarios shown in the sensitivity table.Request list quality audit follow-upShows a B2BOutreach.io audit CTA after the estimate when quality risk is material.

Step 1

Collect lead count, monthly volume, invalid rate, catch-all rate, vendor pricing assumptions, and verification policy.

Step 2

Validate numeric fields, clamp percentage inputs from 0 to 100, and require at least one pricing assumption before producing a cost result.

Step 3

Calculate raw records, duplicate or suppressed records, verification volume, invalid leads, catch-all leads, valid leads, and policy-approved usable leads.

Result workspace
