As you're probably not going to read the full terms here are some of the things that I gather after reading them.
You need to provide them with a credit card or debit card you have 11 months to publish the website if you fail to do so it doesn't appear you'll be charged for the first year of domain name registration provided you turn off auto renewal.
Some other things I'm aware of based on what I've read elsewhere.
You do not get access to the ability to change DNS records however according to what I've read online you can have them add these records on your behalf by filing support tickets.
There is no email hosting attached to the domain name while you could use Mailchimp to set up a mailing list with this domain name ou don't get access to any email hosting. For email you could use Zoho Mail's forever free plan and have support set up the relevant DNS records.
Status of transferring the domain name currently unknown per ICANN policy the domain name has to stay where it is for at least the first 60 days and at this stage it's unclear if you can request a EPP Code for transfer without incurring any cost for the first year at least.
Mailchimp is a Tucows reseller for the domain name registration itself.
So it's till 31/5. Can somebody confirm they managed to redirect that domain to their server or hosting outside Mailchimp?
Also, what does it mean to "publish a Mailchimp website"?
Thanks, OP - great effort!
