Even though the certs are 90 days, the script renews the cert 30 days before it is due to expire. Typically you will run the script once per week via crontab, so you'll get emailed once a day with a message saying either it has renewed the cert, or it isn't ready for renewal. IMO Let's Encrypt is the best way to manage an SSL cert these days.
