Well... im sure many of us aren't new to running servers and already have centralized logging. Most modern server OS have email alerting, I think it's even part of systemd at this point. Otherwise syslog and other common centralized logging systems are so important we all already run them.

rsyslog, vector, grafana, openobserve the list goes on :)

for example proxmox and truenas have "first-class" email alerting as well usually enabled through setup.
