Summary
Yahoo and Google's enforcement of new email sender guidelines involves a phased approach, starting with monitoring and 'soft failures' like spam placement, then escalating to deferrals, increased rejection rates, and eventual blocking. Key to compliance is robust email authentication (SPF, DKIM, DMARC), maintaining low spam rates, and providing easy one-click unsubscribe options. Senders are urged to proactively monitor their sender reputation using tools like Google Postmaster Tools, as declining scores signal deliverability issues. While allowlists aren't a primary enforcement tool, following best practices enhances deliverability chances. The enforcement strongly favors senders with a DMARC policy in place to ensure legitimate email delivery and prevent phishing.

What the experts say
3 expert opinions
Yahoo and Google's enforcement of new email sender guidelines will involve a tiered approach, starting with deferrals, spam foldering, and increasing rejection rates for non-compliant senders. Emphasis will be placed on email authentication (SPF, DKIM, DMARC), with poorly authenticated senders and those with high spam rates facing deliverability issues, including filtering to the spam folder or complete blocking. Direct notification or individualized support is unlikely, requiring senders to proactively monitor and adjust their practices.
