Ending Support for Expiration Notification Emails
letsencrypt.org
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 think it’s a good idea, everyone should be automating this anyway.

    If they send 2 emails per subdomain per year, that could easily be 10s of millions which would make the cost per email measured in thousandths of a cent. And I could see the number of subdomains being larger by a factor of 10, maybe more.

    Another angle: someone with IT experience needs to manage the system that seems emails, and other engineers need to integrate other systems with the email reminder system. The time spent on engineering could easily add up to thousands per year, if not tens of thousands.

    I’m guessing their figure is based on both running costs and engineering costs.
