50K US AR/AP/CFO Emails Needed

I need a fresh, accuracy-checked list of 50,000 U.S. companies with direct business emails for the key finance contacts—Accounts Receivable, Controller, Accounts Payable, and CFO.

Scope
• Sources must be legitimate company websites registered in the United States.
• Every email has to be verified (zero hard bounces). Please run your usual validation tools—NeverBounce, ZeroBounce, Hunter, etc.—before delivery.
• One line per contact in a clean CSV: Company Name, Website, Contact Name (if available), Position Title, Verified Email, Phone Number (optional), State/City, Industry.
• No duplicates across roles or domains.

Acceptance Criteria
1. 50,000 unique, deliverable emails.
2. Overall bounce rate under 2 % on a random 1 k-sample test.
3. Spot checks must show the requested finance titles; generic “info@” or “sales@” addresses will be rejected.

If you already have a compliant database, let me know how recent it is and the steps you took to verify it. Otherwise, outline your collection methodology and estimated turnaround.
