> Let's Encrypt stopped its certificate expiration email notification service a while ago, and I hadn't found a replacement yet.

This sounds like an easy problem to identify root cause for.

I think I received about 15 'we're disabling email notifications soon' emails over the past several months - one of which was interesting, but none were needed, as I'd originally set this up, per documentation, to auto-renew every 30 days.

Perhaps create a calendar reminder for the short term?
