> On the cron case, what are your thoughts on the email notifications? In what ways are the useful or useless? I'm not an expert in this stuff.

I really dislike it. It’s probably the biggest pain point in cron IMO.

1. At the age of DKIM, DMARC and SPF, setting up a working MSA on every server that runs cron can be a real pain. Not always, it depends on the exact situation, but it can be.

2. The biggest issue is that it sends a mail whenever the cron job outputs anything, even if it is successful (exit code 0). This is batshit insane.

3. Nowadays, mail only notification are a bit limitating anyway.
