Hard boundaries
Account, inbound, geography, and compliance.
These distinctions rule out more options than a small price difference does.
- Account
- Just One Fax: no login or dashboard. GotFreeFax: No account for free or premium pay-per-fax; an account is used for prepaid credits.
- Inbound
- Just One Fax: no receiving number. GotFreeFax: The free and premium sending options do not include a private inbound number; a shared public receiving number exists and is explicitly unsuitable for personal or sensitive documents.
- International
- Just One Fax: U.S. destinations only. GotFreeFax: Free and listed premium tiers cover the U.S. and Canada; a separate service reaches 200+ countries at country-specific rates.
- Compliance
- Just One Fax: no HIPAA claim or BAA. GotFreeFax: GotFreeFax does not state a HIPAA or BAA commitment for these options, and its shared public receiving number should not be used for sensitive documents.
