Email Bounce Back Addresses from Collections Emails

Hi,

Do we have any way to understand the number of Collections emails that bounce back when we're attempting to send out delinquency notices?  I'd like to be able to update the billing delivery preference for customers that we know don't have an active email address on file with us (ex. change billing preference from email to paper for these folks to ensure they receive invoices each month).

Appreciate your help on this.

Thanks,
