Let's Encrypt Ends Expiration Email Notifications

Let’s Encrypt stopped sending certificate expiration notification emails on June 4, 2025.

The service was ended because most users now use automated renewal, and to reduce privacy risks, costs, and system complexity.

Third-party services like Red Sift Certificates Lite are recommended for free expiration monitoring.

All stored ACME API email addresses have been deleted, and future provided addresses will only go to a general ISRG mailing list unlinked to issuance data.

Users can sign up for ISRG email lists to stay informed about Let’s Encrypt and ISRG updates.
