The domain(s) listed below are expiring with your existing registrar in the number of days indicated. This is a reminder to renew your registration to ensure your domains remain active.
I mean, I have my domain already registered in Germany through my provider. Do I need to do anything now? or should I ignore these emails?
Which are the domains? And who sent those emails? Cloudflare?
Assuming this was a Cloudflare email and if your domains are not registered with them but with another provider, they’ll be solely of informative nature and - as long as you keep track of your expiring domain - you’ll be good.
Yes, that domain is not registered with Cloudflare, so they won’t have any influence on the renewal. Just make sure you renew with your registrar and you’ll be fine.
