Since its inception, Let’s Encrypt has been sending expiration notification emails to subscribers that have provided an email address to us. We will be ending this service on June 4, 2025. The decision to end this service is the result of the following factors:
Over the past 10 years more and more of our subscribers have been able to put reliable automation into place for certificate renewal.
Providing expiration notification emails means that we have to retain millions of email addresses connected to issuance records.
I mean, they sound like inherit operating costs and requirements to me and I don’t think an email anyone can randomly generate is that big of a privacy risk.
That being said the multiple Emails I get do nothing but clutter up my inbox, I consider the most important part of generating a certificate to be automating it.
