I understand your domain name is suspended because you forgot to acknowledge your details in an email sent to you. Please correct me if I misunderstood.
When you register a domain with AWS for the first time, ICANN requires that you get confirmation that the email address for the registrant contact is valid.If you don't click the link in the email in the allocated amount of time, ICANN requires that AWS suspends the domain.
Please verify on the following link  to check if you followed the correct steps to resend the confirmation email for your domain registration.
Your domain is suspended so therefore it becomes unavailable on the internet.You can use either of the following methods to determine whether your domain has been suspended:
On the Registered domains page of the Route 53 console, find the domain name in the Alerts table at the bottom of the page. If the value of the Status column is clientHold, the domain has been suspended. Send a WHOIS query for the domain. If the value of Domain Status is clientHold, the domain has been suspended. The WHOIS command is available in many operating systems, or you can use the Whois third party site .
To make a domain available on the internet again, you must get it unsuspended and cannot be done on the domain zone setting.
For further assistance on getting your domain unsuspended, you can contact AWS Support 
I hope this was helpful.
