To have a process be remembered, make it monthly or quarterly.
This is vastly more powerful than you need to simply call a shell script which generates SMTP email to your noc@companyname.com address, but can serve the purpose:

You can use this for all sorts of things like maintenance notifications, automated emails to a facilities group on N schedule to change air conditioning filters, whatever needs to occur on a specific recurring time schedule.
The same rule applies to any email address that you use to purchase and renew domains and other critical services. If renewal emails are being sent to someone who doesn't work there anymore, something is very wrong.
Has the advantage that a failure might not be so disastrous either.
Also, get a registrar with an API and use a script to figure out how long a domain is valid. Alarm through your monitoring system when you hit the too close for comfort time frame.
You can scrape whois as well but that seems fragile.
Even as a small company we have a number of regular infrastructure reviews. Most of the time we just go through the review, find nothing has changed unexpectedly and no new ideas need bringing to the table, we sign off to say all looks well, and the prices takes very little time. Some of this is automated: scripts collate and report information for signoff and we humans verify the result and take actions as needed (in some cases the action needed is to update the script(s)). This may seem wasteful, but a couple of people spending a couple of hours total per month on such checks can save some nasty surprises in future.
Domain status checks is one of the things that gets reviewed.
