I get emails from LE when my certs are about to expire. I'm honestly not sure how they do it (based on the email address, I'm guessing that they pulled the email they are using from WHOIS), but it's not something I went out of the way to set up.
I really like it, because it lets me know when I need to go in and kick certbot.
Usually you run Let's Encrypt with something like EFF's certbot, and then you certainly get lots of help to have up-to-date certificates, as long as you installed it in a way so it automatically runs (via cron or whatever you use).
