When a new customer registers I want them to be automatically assigned to a group which is not linked to a payment plan as this will be their initial free plan group for 2000 emails per month. I have 3 paid plans at $10, $20 and $50 per month. I have set up the free plan group not linked to a payment plan but cant work out of I can have new customers automatically assigned to the free plan group. Is this possible or is there a better way. I don't want the customer to have to go through Paypal to register for the free group.
