You are usually warned by email a lot of times before it ever happens. Make sure you receive them on devices and an email address you actually pay attention to.

I also put an entry in my calendar a month before every renewal. The funny part is you need an email address already to register a domain, at least during a bootstrapping phase. I have several domains across 2 registrars with renewals at different time of the year.
