certs.email is a simple tool for automated SSL/TLS certificates monitoring.
Enter your domain names and email address and we'll send you:
Certificate renewal may seem a solved problem, but we still sometimes see website downtime caused by expired certificates, usually because of broken automation or lack of monitoring.
With Let's Encrypt discontinuing the expiration notifications, we decided to build a simple tool to help people monitor their certificates. We focus on a simple user experience: no account creation is needed!
Yes! certs.email is free and open source and allows up to 20 domains per email address.
certs.email is made by the creators of DMARCwise,
a DMARC monitoring product used by thousands of companies.
Your email address is safe and is used only to send you the notifications. Read our privacy policy here.
This project is also open source on GitHub.
If this service only sent expiration notifications, you may at some point wonder if it's working at all. This is why by default we also send you a notification when we detect a new certificate for any of your domains, and one status report (heartbeat) every 2 weeks.
This way, you can be sure that certs.email is actively monitoring your domains, that notifications are still working and that we can reach you correctly (email is all but perfect!).
If you don't find these additional notifications useful, you can disable them from the settings link you can find in any email we send you.
We check your domains every 6 hours.
No, we currently only take the first public IPv4 address returned by the DNS lookup for the domain.
