Renewal Notification Policy
With respect to domain name registration services, it is now a requirement by
ICANN to email renewal notifications approximately 90 days, 60 days, 30 days, 14 days and 7 days before the expiration of a domain name.
If you have auto-renew switched on and have valid credit card details on your account then you can ignore the domain renewal reminders as the domains will automatically be renewed on the due date.
