Critical Change Alert

Let's Encrypt Stopped Sending Expiration Notification Emails

As of June 4, 2025, Let's Encrypt ended their expiration notification service that millions of websites relied on. If you were depending on their email alerts, you're now flying blind when certificates are about to expire.

⚠️ What This Means:

  • • No more email reminders from Let's Encrypt
  • • Certificates can expire without warning
  • • Automatic renewal failures go unnoticed
  • • Website outages become more likely

✅ Certimon Fills the Gap:

  • • Real-time Telegram notifications
  • • Custom reminder periods (30, 7, 1 days)
  • • Works with ALL certificate providers
  • • 100% free, unlimited domains

Plus: Certificate validity periods are getting shorter too! By 2029, SSL certificates will only last 47 days, making monitoring even more critical.
