BillionVerifyGoogle Sheets

Two-way property repair management system with Google Sheets & Drive

Pull contacts, verify each address with BillionVerify, and continue to Google Sheets — only deliverable addresses get through.

Why verify before the send

Sending to invalid, risky, catch-all, or disposable addresses spikes your bounce rate and erodes sender reputation. A verification gate before the Google Sheets step removes that risk automatically — only deliverable addresses continue, the rest are flagged.

The workflow

BillionVerify — verification sits right before the send.
