The Political BIAS Emails Act of 2023 would prohibit major email service providers from automatically filtering emails from political campaigns into spam folders unless the account owner specifically requested that action. The bill defines covered email operators as those with more than 500 employees or annual revenue exceeding $5 billion, meaning major providers like Gmail, Outlook, and Yahoo would be affected. Email companies would be required to publish quarterly transparency reports showing how many political campaign emails were flagged as spam, broken down by party affiliation, and must respond within four days to political campaigns requesting information about their email delivery rates and best practices. The law would take effect three months after enactment, with transparency reporting beginning 120 days after the law passes. The Federal Trade Commission would enforce the requirements and treat violations as unfair or deceptive business practices.
