Task 3 preview · SOW 3.c · capped at 20% of budget by the SOW
UX friction register
The SOW asks for a broad heuristic review of what prevents customers from completing revenue-generating tasks, explicitly not usability testing and not a 508 assessment. This register is the shape of that deliverable: findings scored by severity and revenue exposure. Every entry below is already grounded in a documented source; fieldwork re-runs each walkthrough end to end with screen evidence.
Baymard checkout benchmarks
70.22% average cart abandonment across 50 published studies. Leading checkout-stage causes: extra costs (40%), slow delivery (20%), security concerns (19%), forced account creation (18%), long or complicated checkout (17%). Average US checkout carries 23.48 form elements against a 12 to 14 optimal.
Nielsen's ten heuristics
The scoring rubric for each walkthrough step: visibility of status, match to the real world, user control, consistency, error prevention, recognition over recall, flexibility, minimalist design, error recovery, help.
Comparative walkthroughs
Each revenue task is completed on USPS channels AND the competitor equivalent, so every finding states a concrete contrast in steps, fields, and identity gates rather than an opinion.
Buy a shipping label (Click-N-Ship)
usps.com, desktop + mobile webFindings documentedA third party out-competes USPS at selling USPS postage
S4 · Revenue-blockingPirate Ship sells the same USPS postage free of fees with Commercial Pricing and Priority Mail Cubic passed through, claiming up to 87% off retail and $705M cumulative shipper savings since 2014. USPS extended commercial rates to Click-N-Ship only in July 2024.
Revenue exposure: Every label bought off-channel surrenders the customer relationship, the data, and the cross-sell; intermediaries have begun taxing USPS spend directly (EasyPost 3% fee, June 2026).
Anchor: Baymard: extra costs + complicated checkout
Account required before a price is shown for label purchase
S3 · MajorClick-N-Ship requires a usps.com account and sign-in to reach label purchase; competitor flows (Pirate Ship, UPS basic) quote and sell with lighter gates.
Revenue exposure: Applies Baymard's 18% forced-account abandonment factor to the front door of USPS's flagship digital revenue product.
Anchor: Baymard: forced account creation (18% of abandonment)
Small-seller workflow gaps push volume to intermediaries
S3 · MajorDocumented seller complaints after the 2023-2025 redesign: 10-label batch cap, no marketplace integrations, no automation; loyalty program terminated June 2023.
Revenue exposure: The SMB segment most likely to pay for convenience is the segment the current flow serves least.
Anchor: Nielsen: flexibility and efficiency of use
Counterfeit-label fraud erodes trust in the online channel
S2 · MinorOIG management alerts valued at $485.9M (Oct 2025) and $92.6M (Apr 2026) identify counterfeit-label vulnerabilities across Click-N-Ship, third-party vendors, and retail.
Revenue exposure: Fraud pressure concentrates in exactly the channels the white paper covers; every hardening step must be scored against the friction it adds.
Anchor: Nielsen: help users recognize and recover from errors
Enroll in Informed Delivery
usps.com + Informed Delivery appFindings documentedA structural enrollment ceiling caps the channel's own growth
S3 · MajorEnrollment requires an eligible ZIP and a uniquely coded mailbox; USPS's own page tells residents of some apartment buildings to 'check back later.' National saturation is 34.7% of eligible delivery points (Mar 2025).
Revenue exposure: The ceiling binds the very asset (72.9M users, 45.1B impressions) that any advertising or premium-tier monetization would be built on.
Anchor: Nielsen: error prevention / system status
Identity-proofing friction is the price of a fraud history
S3 · MajorPre-2019 knowledge-based signup was exploited for mail theft; USPS tightened to phone or in-person verification. Online-proofing failure rates are not published anywhere.
Revenue exposure: Unmeasured drop-off at the gate of the largest consumer digital asset; the study should instrument it, since no public figure exists.
Anchor: Nielsen: user control balanced against security
Engagement is high but drifting
S2 · MinorDaily Digest open rate averaged 58.6% (Apr 2024-Mar 2025) but dipped to 54.8% in Q1 FY25; USPS reports NPS 75 and 94% satisfaction.
Revenue exposure: Open-rate decay directly discounts the impression base any campaign-fee model would price against.
Anchor: Comparative benchmark
File a change of address online
usps.com (MoversGuide)Findings documentedThe digital channel costs $1.25 while the counter is free
S3 · MajorOnline COA charges a $1.25 card-based identity-verification fee (raised from $1.10); in-person filing is free. Fraud-driven, per OIG 22-058-R22.
Revenue exposure: Inverted channel economics: USPS taxes its cheapest channel. Roughly $22M/yr collected, while the OIG found the control ineffective at stopping fraudulent COAs ($21.8M impact).
Anchor: Baymard: extra costs (40% of abandonment)
Lookalike sites monetize USPS's own navigation gap
S3 · MajorOIG 22-058-R22: third-party lookalike sites charged $20 to $89.95 and completed over 1M change-of-address requests; USPIS warns of scam sites charging up to $40.
Revenue exposure: Customers pay strangers up to 70x USPS's fee for a task usps.com makes hard to find and trust. MoverSource proved COA attention is monetizable ($51.9M net income, FY2011).
Anchor: Nielsen: match between system and the real world
Complete any purchase in the USPS Mobile App
USPS Mobile (iOS / Android)Findings documentedThe highest-rated carrier app cannot complete a purchase
S4 · Revenue-blockingUSPS Mobile rates 4.8 on iOS (1.7M ratings), best of the three national carriers, but recurring review themes note it is tracking-only: label purchase and most services bounce to the mobile website.
Revenue exposure: USPS earned the audience and the rating, then hands off every revenue moment to a web flow with a fresh login. The 6M+ FY2025 downloads monetize nothing in-app.
Anchor: Nielsen: consistency; flexibility
Maintenance downtime and preview mismatches drain the daily habit
S2 · MinorRecurring review themes: maintenance windows, Informed Delivery previews not matching what arrives, removal of the evening next-day preview, no in-app missing-mail recourse.
Revenue exposure: The daily-habit surface is the natural home for premium features; reliability complaints undercut willingness to pay.
Anchor: Nielsen: visibility of system status
Buy stamps and merchandise (Postal Store)
usps.com storeFull walkthrough in fieldworkThe store's own scorecard regressed in FY2025
S2 · Minorusps.com CX survey scored 73.62 in FY2025 against a 76.95 target, down from 75.53 in FY2024; one of five touchpoints that missed target. ACSI has USPS trailing UPS (77), FedEx (79), and Amazon (81) at 71-72.
Revenue exposure: Full checkout walkthrough with form-element count against Baymard's 12-14 optimal is a fieldwork item; the scorecard already says the trend is wrong.
Anchor: USPS corporate performance data
Where Task 3 concentrates
USPS holds the category's biggest audience and its best-rated app, then routes nearly every revenue moment through its highest-friction flows. The four severity-4 and severity-3 clusters above are where the white paper's Task 3 note would concentrate.
