95% of our customers are perfectly fine with email notifications going to all of their addresses on file, however when customers have automated invoice processing, it would be ideal to send "New Invoice Email" notifications to the invoice processing system and other emails to different email addresses.
Basically, we're wanting more customization on who receives specific notifications. For example, we want the Open Invoices and Past Due reminders to send to a different email from the one we have set for New Invoices.
I would envision that there's the default setting that sends to all like it does now, but it would be nice to have checkboxes for the email addresses on the account for each of the 5 types of communication.
It's totally a wish list item, but seems to have value with up-market customers (any customers that have automated invoice processing).
