I got that email. I read the extremely badly worded email as you have to activate it.
Godaddy own 123-reg ? News to me.
I have 100+ domains with them I swore I would never use Godaddy after their anti net neutrality support.
We are Gsuite so look at Google Domains today.
Another thing that annoys me about 123 is i'm on direct debit but they put renewals in my basket when I buy new domains via my company credit card.
