Although CUPS has a method for sending emails about certain situations
(e.g. job aborted), this isn't one of those situations.

However, you could write a small application to periodically check for
the 'marker-supply' state reasons, marker-supply-low-warning and
marker-supply-empty-error.

In Python it can be checked like:

import cups
c=cups.Connection ()
for printer in c.getPrinters ():
    for reason in printer.get ('printer-state-reasons', []):
        if reason.startswith ('marker-supply'):
            # This printer is low on ink/toner
            break
