结束对过期通知电子邮件的支持

发布于 1 月 22 日

Summary: Let's Encrypt has been sending expiration notification emails since its start and will end this service on June 4, 2025. Reasons for ending include subscribers' ability to automate certificate renewal, privacy concerns (retaining email addresses), cost (tens of thousands per year), and complexity in infrastructure. For those who want to continue receiving notifications, a third-party service like [Red Sift Certificates Lite] (formerly Hardenize) is recommended. It's free for up to 250 certificates, and more monitoring options are available. Let's Encrypt will minimize retained email addresses but allows users to opt in for other emails about technical updates and news. Users can sign up for email lists.
