Google introduces new security rules for Gmail business accounts

Google celebrates Gmail's 20th birthday with new security tools for business accounts. New spam protection rules, effective April 2024, require bulk senders to authenticate emails, maintain a 0.3% spam rate, and offer one-click unsubscribe options. Non-compliance may lead to rejected emails or spam folder placement. Google advises senders to address issues during a temporary error phase before full rejection begins in April.
