To this day, every Sunday I get e-mail via a cron job that runs domain-check against a set of about three dozen domains (mine, friends', and those of institutions I care about) to tell me which of them are within 90 days of expiration (and if any are past expiration).
FYI, here's an example report sent using said cron job, that leverages Ben Okopnik's 'domain-check' Perl script: ---<begin>--- Date: Sun, 24 Dec 2017 07:12:02 -0800
