Automated email response to customers

[Sublimity]

1) Project Details: (be as specific as possible):

I've searched the net and have yet to find a suitable programme/software that would fulfil my requirements.

Basically, I need some form of automated software/programme that upon purchase will send out a confirmation email (confirming received payment, estimated delivery time etc) and then also a following email (which requires authorisation from myself/automated authorisation for verified buyers) that forwards on a unique information to that specific customer.

So, to put this into a hypothetical context; I have a mobile phone website, that sells top-up cards online. I would like this process to be instantaneous to verified (previous) customers. However, for first time buyers I would like this to require me to accept authorisation of delivery, which would then on future purchases be instantaneous to that buyer.

The automated emails I would require are:
Confirmation of payment - to all customers instantaneously
Email containing the top-up code. Sent out instantaneously to verified buyers, but requires a one time authorisation for first time buyers.

The email containing the code would need software/programme that has an inventory of unused codes that can be sent out one-by-one to customers and can easily be updated.

2) Payment Amount: Estimates?

3) Payment method/ details (Paypal, check? Timeline?): Paypal

I hope this makes sense, any questions please feel free to ask. Also, please elaborate exactly how your proposal will work and how easily it is to maintain and update.

Thanks in advance!
