A widely used certificate authority has announced a significant change: they are discontinuing automated email notifications regarding certificate expiry. This decision was made primarily to achieve substantial cost savings, as sending millions of emails annually represents a considerable expense.
Furthermore, the move aims to enhance user privacy. By no longer needing to store and manage email addresses for notification purposes, the organization reduces potential privacy risks. While this change impacts many users who relied on these reminders, it underscores the importance of using automated renewal methods, such as those built into most modern ACME clients. Users should ensure their renewal systems are correctly configured and potentially implement alternative monitoring tools to track certificate validity proactively.
