The order form now checks Full Control domains for existing email before you pay, and fills in your registrar for you.
If you bring your own domains, the order form now looks each one up while you type. A domain that already sends or receives email gets flagged right there, with the mail records we found, and you decide whether we should replace them before the order goes through. That question used to surface days into setup, after payment.
Two smaller changes in the same step:
The form reads your domains' nameservers and fills in the registrar dropdown when they all point at one place. Your own pick always wins, and you can change it any time.
The manual-setup details for GoDaddy, Namecheap, and Hostinger orders now sit in a single notice with the fee math up front, instead of three stacked boxes.
