Since Dec 2016, ICANN is implementing a new policy on the domain information.
Every time, when any changes made on domain registrant information (e.g. first name, last name, organization, and/or email), it will trigger a IRTP validation.
For IRTP validation, domain registry will send 2 approval emails. One to existing registrant contact email, another one to new registrant contact email.
Inside the 2 confirmation emails, there is a confirmation link in each email.
Both existing registrant contact and new registrant contact click on the link, and confirm the change.
Email Subject: Change of Registrant request for email-solution.net – (Current/New) Registrant. Action Required.
For details, please refer to https://www.icann.org/resources/pages/transfer-policy-2016-06-01-en , section: Inter-Registrant Transfer (Change of Registrant)
