Sometimes you may  receive an email with one of the following subjects:

“WHOIS Data Confirmation for yourdomainname.com”

“Important Notice: Please Verify Contact Data for your Domain Name(s)”

Those reminders are sent in order to keep your domain information up to date. It is important to keep the information of your domain up to date, because this will identify that you are the owner of the domain. That is why we always recommend you to keep your information up to date. Those email reminders are sent by ICANN (The Internet Corporation for Assigned Names and Numbers) on behalf of TMDHosting and they are standart practice for every registrar and registrant. If the information for your domain is accurate and it does not need to be changed, you should not do anything.
