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.
I just realized I have no idea who pays for Let’s Encrypt. I just run the server commands, automate it, and move on.
Let’s Encrypt is run by a non-profit (Internet Security Research Group), they list their major sponsors and funders on their website.
Notable mention of Mozilla being a Platinum sponsor.
