Let’s Encrypt Expiry Bot Alternative for Certificate Expiry Notifications
If you searched for “Let’s Encrypt expiry bot”, “expiry.letsencrypt.org alternative”, or “Let’s Encrypt certificate expiry notification”, Certimon fills the gap with free Telegram alerts before SSL certificates expire.
What changed with Let’s Encrypt expiration notifications?
Let’s Encrypt used to send expiration notification emails to subscribers who provided an email address. In January 2025, Let’s Encrypt announced that this service would end on June 4, 2025.
That means teams who relied on Let’s Encrypt expiration emails need their own certificate monitoring. If renewal automation fails, an expired certificate can still take a production site offline even when you use ACME or Certbot.
