Just got our last certificate renewal email ever.
For years we paid DigiCert $144/year for a wildcard. Click button, enter payment, download cert, install manually, set calendar reminder. Repeat forever.
All our products are now fully automated with CertKit. Let's Encrypt issues certs automatically, CertKit handles discovery and distribution. Zero human intervention, zero annual fees.
This email goes straight to the trash. We're done paying the certificate tax.
