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.
True. And there’s also a ton of devices around which don’t trust LetsEncrypt either. There’s always edge cases. For example, take a bit older photocopier and it’s more than likely that it doesn’t trust on anything on this planet anymore and there’s no easy way to update CA lists even if the hardware itself is still perfectly functional.
That doesn’t mean that your self-signed CA, in itself, would be technically any less secure than the most expensive Verisign certificate you can find. And yes, there’s a ton of details and nuances here and there, but I’m not going to go trough every technical detail about how certificates work. I’m not an expert on that field by any stretch even if I do know a thing or two and there’s plenty of material online to dig deep into the topic if you want to.

I’m good. I know very well there are uses cases for a self signed cert. LE is still far more practical for 99% of use cases, even internally.
