Why users leave
The free diagnosis shows the top complaint. The full brief has every cluster, the build ideas and the buyers.
Tracker warns only after send that plain-text emails are untracked, so important emails go out without tracking.
“As soon as I hit send it said "This email is in plain text mode so it will not be tracked". NOW my email is already sent!! It should have told me that before.”

How to read this
Sources: the product's public listing and reviews, its published price, and public forum threads. Revenue is an estimate unless marked verified by the founder; the formula and its inputs are on the full x-ray. Complaints are grouped by a language model and each quote is a verbatim excerpt, linked to the original review. Build difficulty is a model's reading of the listing and the complaints, not a measurement. Figures are a snapshot of Nov 1, 2026. Corrections: corrections.
