01Friction map
Three things to fix first
Ranked the same way every paid audit ranks issues — by what a stranger notices first.
Proof — 0/10
No customer name, logo, usage number, or case study anywhere on the page.
Fix: Add 3 named proof elements under the hero — a live usage counter, a named early user with role, or a linked write-up.
CTA — 2/10
“Loading inbox information” — the only primary button above the fold ships disabled and empty (aria-busy="true", no visible label) in the fetched HTML; it depends on client-side JS to appear.
Fix: Server-render the button with its final label and enabled state, e.g. “Create a mailbox — no signup.”
Audience — 3/10
“Your temporary mailbox. In one click.” — the hero never names who the mailbox is for; “Developers” only appears as a nav link, not in the pitch.
Fix: Name the buyer in the hero, e.g. “Disposable email for developers testing signup flows and verification codes.”
