Task 4 support · every assumption exposed as a slider
Sizing sandbox
The SOW asks for estimated revenue from new streams. Estimates are only as honest as their assumptions, so ours are sliders. Baselines come from USPS-published figures (72.9M Informed Delivery users, 45.1B impressions, 58.6% open rate); the adjustable parameters are the things nobody can know before fieldwork, set here to conservative defaults. Everything computes in your browser; nothing is recorded.
Informed Delivery campaign fees
campaigns priced per year
per year, illustrative
Baseline: 1,025,694 campaigns completed cumulatively through Mar 2025, priced at $0 today. RISC-WP-21-005 says ROI measurement must precede pricing; the adoption slider models mailers who churn when fees arrive.
Digest sponsorship (CPM basis)
impressions monetized
per year, illustrative
Baseline: 45.1B impressions Apr 2024-Mar 2025 (USPS Year in Review). CPM defaults to the low end of display norms; sell-through reflects how much inventory USPS would actually offer.
Premium package-management tier
paying subscribers
per year, illustrative
Anchored to UPS My Choice Premium at $19.99/yr. No public attach-rate benchmark exists; the conversion slider is the honest uncertainty.
Reimbursed identity proofing (PSRA lane)
proofing events
per year, illustrative
Cost-recovery utilization rather than profit: PSRA section 3703 requires reimbursement of at least 100% of attributable costs. Login.gov in-person verification at post offices is the live precedent.
These are planning illustrations for a white paper, not forecasts. In the deliverable each estimate carries its statutory pathway (including the 39 U.S.C. 3641 revenue caps where they bind), its precedent, and a stated confidence band, and the OIG’s internal channel data (research questions 1-3) would replace public proxies wherever it is stronger.
