Transparency is core to how we operate. Here is exactly how SIndbox Intel finds, verifies, and maintains the B2B email data that powers your outreach.
100% of our data originates from publicly available, ethically sourced channels.
We aggregate publicly available professional data from company websites, professional networks, job boards, SEC filings, press releases, and public directories. No scraping of private data — ever.
Our ML engine identifies email naming conventions for each organization (e.g., first.last@, f.last@, firstlast@). We analyze patterns across millions of companies to predict the most likely address format.
Every candidate address passes through 7 verification layers: syntax check, DNS lookup, MX record validation, SMTP handshake, catch-all detection, disposable domain filtering, and deliverability scoring.
Each email receives a confidence score from 0 to 100 based on verification results, pattern strength, source corroboration, and historical deliverability data. You always know how much to trust a result.
Email addresses are not static. People change jobs, companies rebrand, and servers change. Our system continuously re-validates stored data to ensure freshness and flag stale addresses.
We process data in accordance with the EU General Data Protection Regulation. Users have full rights to access, correct, and delete their data.
Our data practices comply with the California Consumer Privacy Act, giving users transparency and control over personal information.
Our infrastructure and processes are audited under SOC 2 Type II standards for security, availability, and confidentiality.
We never sell individual personal data. Our business model is subscription-based, not data brokerage.
We benchmark our accuracy weekly against industry standards and publish results transparently. If you ever receive an inaccurate result, our team investigates the root cause and feeds it back into our engine to prevent recurrence.
