Kulea is all about sending out targeting communications to good quality customer/prospect data. That's what we do, and we're sure that's what you want to do to.
To help you in this mission, we auto-suppress (archive) any contacts that return a hard bounce back when you email them.
A hard bounce back generally means that the person is no longer available at the email address you've contacted them on (maybe they've left the business, maybe the business no longer exists!). By auto-suppressing these emails, we prevent you sending out communications to invalid addresses that may potentially damage your sender reputation with email service providers such as Google or Yahoo.
