You will receive notices when your domain is due for renewal. Our policy is to send them at 7,3 and one day's notice. Obviously, if the domain is renewed then notices will be stopped
NOTE: You MUST renew your domain name at least 7 days before it expires. If you leave it past the expiry date, the domain will be locked down and you will not be able to access your site.
If your domain has expired past 30 days it will go into REDEMPTION mode. Once it switches to this you will have to wait 60 days before the domain is free to register once again.
