Was Click-N-Ship use already visible before the Stamps.com lapse?
Yes. During the paid-tenure window, 7.2% of users who later lapsed had also used Click-N-Ship, versus 2.8% of retained users. The later lapse rate was 19.5 percentage points higher for the 121 dual users, or about 1.45 times the rate for the 2,263 Stamps.com-only users.
Did Click-N-Ship activity continue after the Stamps.com lapse?
Click-N-Ship appeared after the tenure window for 5.2% of users who lapsed and 2.9% of retained users. Only 19 users first showed a Click-N-Ship receipt after the Stamps.com receipt gap, so this small count is uncertain.
Does the overlap show that Click-N-Ship caused the lapse?
No. Dual users may differ in shipping volume, tenure, or price sensitivity. The result shows that outside usage preceded and identified a group with a higher observed lapse rate; it does not establish that the free USPS tool caused those users to stop paying Stamps.com.
Assumptions & Methodologies
We analyzed 2,384 established U.S. e-receipt panelists with a Stamps.com receipt from July 2024–June 2025 and continued panel eligibility. Dual users also had a clean USPS Click-N-Ship receipt in that window. Lapse meant no Stamps.com receipt from July 2025–August 2026. The dual-user group contained 121 users, including 76 observed lapses, so its exact rate is an estimate. Partial receipt capture can inflate both lapse rates; the analysis interprets the between-group contrast, not confirmed cancellation or causality. Noisy Pirate Ship and Pitney Bowes text matches were excluded.
