Let's Encrypt stopped warning you. We didn't.

Those "your certificate expires soon" emails ended on 4 June 2025. Get them back, and better.

What changed

Let's Encrypt ended its expiration notification emails on 4 June 2025 and deleted the stored addresses (sources: letsencrypt.org/2025/01/22/ending-expiration-emails, letsencrypt.org/2025/06/26/expiration-notification-service-has-ended.html). If Certbot fails now, nobody tells you.

Your new safety net

Add your domains. We warn you at 30, 14, 7, 3 and 1 day, and the moment a cert breaks. Email, Slack or Teams. Every alert says why renewal failed and how to fix it, like a rate limit, a failed HTTP-01 challenge or a missing DNS record.
