Personal touch, for sure.
I'd rather wait for manual account verification and phone verification from the hosting provider, as we do to our own clients. "Hey there Bob, this is Joe from [company name] and we're just reviewing your account details and confirming your phone number on file. Your account should now be active and you will be receiving an email soon with the details. While I have you on the phone, do you have any questions regarding your account?"
That'll woo new customers and let them know you're on top of your business. We go further than that, but thats something anyone and everyone CAN do yet most do not.
