It is very important to keep your contact information up-to-date at all times so that you receive important notifications about your domain name from your registrar. These notifications are typically sent via email, and if your email is not updated, you may not receive important notifications that are designed for your protection. For example, your registrar will notify you of changes to your account and domain name registrations so that you can confirm the changes. If your email information is not up-to-date, unauthorized changes could be made to your account without your knowledge.
