Very useful project! The great thing about email is that it's proactively pushed to all your devices, and the client keeps track of what you've already looked at. You're given powerful tools like labels and folders to organize the alerts and filter them as you see fit. Years ago I built a little REST API for sending emails to myself. The main advantage is that you don't have to bother setting up a mail server. I still use it constantly for personal projects. It's just the quickest way for me to make my webapp tell me about new user registrations, or for some random Google Apps Script I wrote to let me know about an unexpected condition, or for me to create a bash script that tells me when my VPS is running out of disk space. I've even written scripts to monitor election results or check websites for vaccine availability. I never did much to promote it, but anyone's welcome to use it as well (website: varmail.me). While I have had almost no downtime, I wouldn't rely on it for something that needs a particular SLA :). Edit: I forgot to mention another tiny feature that I use all the time. The API lets you specify an idempotence key that will prevent the email from being sent if it's already been used. It's very useful to be able to only send an email the first time a user takes a certain action, or to set it to time()/86400 and only get one disk space reminder email per day. I've found a lot of uses for that.
