Checker feedback, guide corrections, questions: email hello@preflightpress.com. If a guide's numbers disagree with what KDP shows in your account, tell us — specifications change, and corrections with a source are always welcome.

A deeper check of your book: the paid deep-check service (full cover/interior/metadata audit with a written fix list) is booked through the Fiverr listing linked from the checker page, so payment and delivery stay inside Fiverr's protection.

Please do not email manuscript files unless we ask for them — the free checker runs entirely in your browser precisely so your files never have to travel.
