Hi, As a Let’s Encrypt Subscriber, you benefit from access to free, automated TLS certificates. One way we have supported Subscribers is by sending expiration notification emails when it’s time to renew a certificate. We’re writing to inform you that we intend to discontinue sending expiration notification emails. You can learn more in this blog post: https://letsencrypt.org/2025/01/22/Ending-Expiration-Emails Here are some actions you can take today: Automate with an ACME Client that supports Automated Renewal Information (ARI). ARI enables us to automatically renew your certificates ahead of schedule should the need arise: https://letsencrypt.org/2024/04/25/guide-to-integrating-ari-into-existing-a… Sign up for a third-party monitoring service that may provide expiration emails. We can recommend Red Sift Certificates Lite, which provides free expiration emails for up to 250 active certificates: https://redsift.com/pulse-platform/certificates-lite Opt in to emails. While we are deprecating expiration notification emails, you can opt in to continue to receive other emails. We’ll keep you informed about technical updates, and other news about Let’s Encrypt and our parent nonprofit, ISRG, based on the preferences you choose: https://letsencrypt.org/opt-in/ If you are receiving this email in error, unsubscribe at: http://delivery.letsencrypt.org/track/unsub.php?u=30850198&id=0f064cc97… All the best, Let’s Encrypt
