.supply is about average for the internet. Across 6,997 graded .supply domains, 73.1% score an F — roughly in line with the 73.8% global average. 2.8% earn a B or better. Most .supply domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-07-29.
How do .supply domains score?
Aggregate grade distribution across all graded .supply domains — we never publish an individual business's grade. As of 2026-07-29.

Does .supply make a domain secure?
No — and that's the most important thing to know. A domain's grade is decided by how it is configured (SPF, DMARC, HTTPS, DNS), not by its ending. Choosing .supply doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .supply domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .supply safe?
On average, .supply is about average for the internet: 73.1% of its 6,997 graded domains score an F as of 2026-07-29, against a 73.8% global average. Most domains on every ending are exposed — the ending shifts the odds, not your own domain's grade.
How secure are .supply domains?
26.9% of .supply domains score above an F and 2.8% earn a B or better. The rest fail the basic externally observable protections, most importantly enforced SPF and DMARC, so they can be impersonated in email.
Does choosing .supply make my domain secure?
No. A domain's grade comes from how it is configured — SPF, DMARC, HTTPS, DNS — not from its ending. A well-configured domain earns an A on any ending; an unconfigured one sits at F on .supply too.
What does "grade F" mean for a .supply domain?
It fails the basic protections we can observe from outside — above all, it has no enforced SPF and DMARC, so its email can be forged and its customers targeted with convincing fakes.
