Let's Encrypt Drops Automated Certificate Expiration Emails

Let's Encrypt, the non-profit providing free wildcard SSL certificates, will cease sending automated expiration emails starting June 4, 2025. This change, however, is likely beneficial. Reasons cited include widespread automation of certificate renewal by users, the significant cost (tens of thousands of dollars annually) and infrastructure complexity of sending these emails, and importantly, enhanced user privacy by eliminating the need to store millions of email addresses. Let's Encrypt suggests using alternatives like Red Sift Certificates Lite for free certificate expiration monitoring.
