It is an ICANN message, a global unit responsible for controlling global domain addresses (of the type .com, .net ..). It requires verification of the subscriber's identity by confirming the e-mail address assigned to the domain.
If a domain is blocked by an ICANN message, check the e-mail address that was provided during domain registration and find the e-mail sent from email@example.com, and then click on the activation link in it.
Once approved, the page will be unlocked.
If you do not have such an e-mail on your mailbox and you are sure that you are checking the correct mailbox - write to the Service Office - we will ask the register to re-send the message.
