<span class="s1">In an era where email remains one of the most widely used tools for personal and business communications, Outlook is stepping up its commitment to protect inboxes and preserve trust in the digital ecosystem. Today, we\u2019re announcing new requirements
and best practices designed to strengthen email authentication for domains sending more than 5,000 emails per day. </span></p>

<span class="s1">These new requirements will enforce stricter standards by including mandatory SPF, DKIM, DMARC settings. Outlook is pushing the broader industry toward best practices and safeguarding the millions of individuals and small businesses that rely
on us every day. These measures will help reduce spoofing, phishing, and spam activity, empowering legitimate senders with stronger brand protection and better deliverability. </span></p>

<span class="s1">Outlook has always prioritized user safety and reliability; we\u2019re proud to further invest in this solution that will keep our customers safe and reinforce the best practices across the industry. We believe that by raising the bar for large
senders, we can inspire lasting change that benefits everyone. </span></p>
