I'll update this if I find more. For now, this seems to be a partial solution. It's a Gmail add on (except I don't use Gmail) that adds reminders. The options when setting reminders include cancelling it if someone replies, and to remind everyone in the thread. If you combine those two, it seems like — if you use Gmail's web client and have $23/month you're dying to get rid of — a decent way to add the feature. Source: over 1 year ago
Statuscake.com if you just need a simple up/down monitor. Source: almost 2 years ago
I've had a great time with statuscake.com for my personal and friends sites. They've even improved custom status pages to include an automatically signed certificate too, so you can make a site like status.yourdomain.com... Test TCP connection, specific HTTP/HTTPS query etc. 5 minute intervals for free, more with paid plans. Source: about 2 years ago
