Sorry for the confusion; in fact, we do send notice of pending payments for eCheck-funded payments if we receive IPN from PayPal notifying us of that. We depend on IPN to receive order notification from PayPal, so if they don't send us IPN for a given order (e.g., if PayPal disabled IPN for your account), we have no way of knowing that order was actually placed to begin with, let alone whether its payment status is Pending or Completed.
If you are having to manually approve Pending payments in PayPal, please see this help page for further instructions to help automate that:

If you receive a Suspected Fraud notification from us, that indicates we received IPN for an order where the amount paid does not match the current price in Seller Admin for the item(s) ordered, so in that case we do NOT process the order and instead send you the order data in a Suspected Fraud email, so you can decide how to handle the situation.
