From the 1st January 2014 it has now become a mandatory requirement from the Internet Corporation for Assigned Name and Numbers (ICANN) that all registrars verify the WHOIS contact information held against new domain registrations, domain transfers and registrant contact modifications.
The domain names affected are top-level domains such as .com, .net, .biz, .org etc.
If you do not respond to a verification email the services associated with the domain i.e. website and/or emails will cease to work.
Emails will be sent from the registrar and will contain a verification link to confirm your email address. You have 15 days to verify your email address. If the email address is not verified within these 15 days the domain name will be suspended until the email address is verified.
The big problem...
If your domain name is old you may have used an email address when registering that is no longer valid. The correct procedure when changing an email address is to notify the registrar or supplier of your domain name so that they can update the email contact details.
If you have changed your email address and NOT notified the supplier there is a high possibility that the email address recorded against your domain is invalid. The registrar sends the verification email to the 'old' email address and may not receive a reply. After 15 days the domain gets suspended and your website and/or emails will stop working.
A quick check...
Using a WHOIS lookup such as http://www.domainwhitepages.com/ you can search for your domain and check the contact details recorded. Look for the email records shown, if they are incorrect, notify your supplier immediately.
