Getresponse Plugin

I'm currently using aMember v3.x and installed the Getresponse plugin.

I also use 1ShoppingCart which is integrated with amember.

I created a product in aMember and assigned a Getresponse campaign to it, so users would get an email after purchasing a product.

However, since the sequence of the sign up process is:

1. Fill out amember form
2. Enter payment info into 1 shoppingcart

The user gets the GetResponse email after completing the amember form, and before entering the payment. So if someone abandons the shopping cart, they still get the email.

Is there any way to delay the email to trigger sending after completing the shopping cart process?

Thanks
