Google Postmaster Tools on a Mac
Gmail sender reputation & spam-rate data (cloud) · Email Deliverability & Reputation
Google Postmaster Tools shows how Gmail sees your sending domain/IPs — domain & IP reputation, spam rate (the key <0.3% target), authentication pass rates (SPF/DKIM/DMARC), encryption and delivery errors. Verify your domain to see dashboards, or pull data via the Postmaster Tools API (service account). Essential for hitting the bulk-sender requirements; keep credentials in Keychain.
