Which software brands can be spoofed in email?
SaaS vendors live and die on customer trust - a single spoofed 'reset your password' email from a fake version of your vendor can poison the whole customer base's perception. Most modern SaaS platforms enforce DMARC strictly; legacy enterprise software vendors lag.
Spoofable
0 (0%)
No DMARC, or DMARC at p=none. Anyone can send from these domains.
Partial protection
6 (30%)
DMARC at p=quarantine, or p=reject with pct<100. Spoofed mail may slip through.
Not practically spoofable
14 (70%)
DMARC p=reject pct=100 + SPF -all or DKIM. Spoofed mail rejected at SMTP.

What does "spoofable" actually mean?
A domain is spoofable when a third party can send mail FROM addresses at that domain (e.g. [email protected]) and have it land in inboxes. The mechanism that prevents this is DMARC enforcement combined with SPF and DKIM. Without all three, receivers have no policy to apply against unauthorised senders.
