Debounced Google Workspace Construction Leads

I’m looking for a steady stream of highly accurate commercial-construction leads that I can plug straight into Google Workspace. My top priority is lead accuracy, and every record must already be debounced so I don’t waste sends on bad email addresses. Here’s what I need delivered: • Only commercial projects—no residential or industrial mixed in. • For each lead, include the decision-maker’s name, role (CEO, Owner, AP, AR, Project Manager, CFO, President), direct email, and direct phone if available. • The data should arrive in a shared Google Sheet (or pushed via Google Apps Script to a Workspace database) with your debouncing results clearly flagged so I can see pass/fail status at a glance. Acceptance criteria • Bounce rate stays below 2 % on my first campaign send. • All emails conform to CAN-SPAM best practices—no scraped generic admin@ or info@ addresses. • At least 90 % of leads show matching company and project details when spot-checked against public records or Dodge/ConstructConnect listings. If you already use tools such as NeverBounce, ZeroBounce, or BriteVerify, let me know—otherwise outline your validation workflow. I’ll start with a small batch to verify quality and scale up quickly once the numbers prove out.
