⚡ What Does This Actor Do?

Given a decision maker's name and company domain (or LinkedIn profile URL), this Actor discovers and verifies their direct corporate work email address using a 5-Layer Deliverability Waterfall:

1. DNS MX Record Resolution & Infrastructure Profiling: Resolves primary corporate mail exchangers and profiles security gateways (Google Workspace, Microsoft 365, Proofpoint, Mimecast).
2. Top 10 B2B Permutations & International Transliteration: Generates industry-standard corporate patterns (first.last, first, f.last, flast, first_last, etc.) with full Nordic/German umlaut transliteration (ö/ø $\rightarrow$ oe).
3. Multi-Hop SMTP Permutation Loop: Probes candidate email permutations in order of prevalence against destination mail exchangers to pinpoint the exact, live deliverable mailbox (e.g. discovering yrangan@hubspot.com over invalid yamini.rangan@hubspot.com).
4. Catch-All (Accept-All) Protection: Probes mail servers with random tokens to detect catch-all domains, preventing false 100% deliverability claims that damage sender reputation.
5. SEC EDGAR Regulatory Footprint: For enterprise security gateways that restrict direct SMTP probes (e.g. Proofpoint), the engine cross-references official US SEC EDGAR filings (Form 8-K, Form 4, 10-K, Form D) to corroborate active corporate officers.
6. Ready-to-Send Cold Email Copy: Produces personalized email subject lines and conversation hooks tailored to each verified contact.
