Hi, I combined many cron notifications into one email to save money, reduce noise, prevent being blocked, and not overload your inbox.

There are several use cases for FastCron. Some have a large number of cronjobs, and some run cronjobs frequently (up to every 5 seconds). Having separate email notifications for each cronjob failure/success is not practical and helpful for both senders and receivers.

Anyway, I don't combine Slack notifications, so give it a try.

I hope this helps.
