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. As an organization that values privacy, removing this requirement is important to us.
I think it’s a good idea, everyone should be automating this anyway.
Providing expiration notifications costs Let’s Encrypt tens of thousands of dollars per year
Not doubting them, but I don’t understand how that’s possible.
Storing the email addresses and expiration dates takes an irrelevant amount of storage space, even if they had billions of cutomers.
Sending the emails should also not cost thousands, even if a significant amount of customers regularly let their certificates expire (which hopefull isn’t the case).
So where are the tens of thousands of yearly costs coming from?
