01 · Investigation Brief
Investigation Brief
sav.sendio.net is a functional subdomain used by Sendio Technologies to perform automated email sender verification. The domain redirects to the company's main product page and shows no signs of malicious behavior or deceptive commercial practices.
Technical Purpose and Evidence
The subdomain sav.sendio.net serves as part of Sendio's Sender Address Verification (SAV) system, which automatically sends verification emails to challenge unknown senders and confirm they are legitimate before allowing messages into the recipient's inbox.
When accessed directly, the domain redirects to http://www.sendio.com/solutions/opt-inbox/, which is expected behavior for a technical verification endpoint not designed for direct user navigation.
Commercial Context and Operator Identity
Sendio Technologies operates as a legitimate provider of enterprise email security solutions, offering products including Opt-Inbox and Email Security Gateway. The site contains standard commercial CTAs such as 'Request Quote' and 'Contact Sales' links directing to sales@sendio.com.
The registrable domain sendio.com is over 23 years old (8568 days), providing strong legitimacy signals consistent with an established enterprise software vendor rather than a newly created malicious domain.
Why the score is 92
The score combines saved deterministic evidence with the grounded analysis available for this report. Coverage remains separate so missing sources cannot be mistaken for clean results.

The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.
