Reaching out regarding the end of support for expiration notification emails.
From the documentation it is clear that notifications are sent out on a best effort, 20 days and 7 days before a certificate expires.
While I am exploring some options for certificate expiration notifications, I wanted to clarify if Let's Encrypt sends a notification when a certificate has already expired (haven't had any issues with expired certificates so far, so I'm not really sure) and if so, will this be deprecated too?
Providing expiration notification emails means that we have to retain millions of email addresses connected to issuance records. As an organization that values privacy, removing this requirement is important to us.
I guess not, as they are want to abandon email address - issuance record
