Blacklist Profiles\Lashback's Bblacklist
LashBack's unsubscribe blacklist (""UBL"") is a unique, real-time blacklist of IP addresses which have sent email to addresses harvested from suppression files. There are approximately one million IPs on the UBL and it is updated on an hourly basis.
The listings are determined objectively and systematically. Only IPs that send email to specially-created, LashBack owned-and-monitored email addresses (unsubscribe probes) -- that are used only on suppression lists -- are blacklisted.
LashBack has been monitoring unsubscribe compliance for more than a decade and this effort has resulted in, what we believe to be, the world’s largest unsubscribe intelligence database.
