Here's the bash snippet:

LETSENCRYPT_CERTS=("mydomain.com")
    for CERT in "${LETSENCRYPT_CERTS[@]}"; do
      CERT_STATUS=`ssl-cert-check -c /etc/letsencrypt/live/$CERT/cert.pem | tail -n+4 | awk {'print $6'}`
      echo "  $CERT"
      if [ $CERT_STATUS -le "1" ]; then
        echo "  CERTIFICATE NEEDS RENEWAL!"
        slack "SSL certificate for $CERT needs renewal!"
      else
        echo "  CERTIFICATE OK!"
      fi
    done
