Let's Encrypt to cease expiration notification emails in June 2025

Let's Encrypt announced it will stop sending expiration notification emails to subscribers on June 4, 2025. This decision comes as more subscribers have automated certificate renewal, and the organization is prioritizing privacy by eliminating the need to retain millions of email addresses. Cost and infrastructure complexity are also factors. Let's Encrypt is recommending using a third party service to users that want to keep receiving expiration notifications.
