Spitballing an idea....

I wonder if you might consider setting up a HTML page with live system info on the PI...

...and then use a free monitoring tool like uptime robot to get your emails:

Mike,

I've done something similar with detecting when my well pump comes on.
The email part was pretty straight forward because Linux has a number of
command line email clients.

I used:
  mutt - email client
  postfix - email server
  paclink-unix - winlink support

For the AC detection circuit I used a Linrose B2150A3 Amber Neon Pilot light as
an Opto-isolated AC Voltage Sensor. Some links below for reference:

I would run the RPi from 12 Volts using some buck regulator.
