Dont want default setup email to be sent out.

I have my own account setup email which is much nicer than the one that comes with HC.
I do not want for HC to email to the customer anything when the account is setup.
If I stop HC delivery service that will also stop all trouble ticket email delivery or quota delivery.
How can I accomplish this ?

I think if you remove the related email template you will achieve the goal.

UPDATE - now you can disable welcome email from Reseller > My Server > IIS Settings.
