Yeah, NameCheap is pretty flaky with the warning emails. I once had their WhoisGuard service expire (it was on a different renewal phase from the actual domain, for some reason), and I never received any warnings about the service expiring until they sent an email to notify me that the WHOIS records had been automatically updated. I've since added a monthly calendar reminder to log in to all registrars and verify all services are still enabled and correctly configured with plenty of time left.
