The Inbox Test: Why 43% of Your Emails Never Arrive (And the $0 Fix That Changes Everything)

Your invoices, quotes, and customer replies might be vanishing before they ever reach an inbox — and you'd never get a single error message warning you. In 2026, Gmail and Yahoo's sender rules went from polite suggestion to hard enforcement, and most small business owners have no idea they're already failing the test. In this episode we follow one furniture maker who lost a $3,000 job to his own email, then walk through the exact free, afternoon-long fix: checking your DMARC record, publishing one with reporting, auditing SPF against the 10-lookup limit, verifying DKIM, and turning on Google Postmaster Tools. We break down what SPF, DKIM, and DMARC actually do in plain English, why the 0.10% spam complaint rate matters, and how the 0.30% threshold can lock you out for seven days.
