Who would want to steal suppression lists?
There are many unsavory “Emailers” out there that would love to get their hands on your suppression files, primarily because those files are validated addresses and guaranteed deliverability (to a real person). What better guarantee of reaching an email recipient than one who has specifically requested NOT to receive email to a specific address? Not to mention the tangible “black market” value on a suppressed email addresswhich ranges from $25 – $35 per address. Multiply that dollar figure by the enormous amounts of commercial emails sent daily… Let’s just say that’s A LOT of people (internally and externally) that would want to steal suppression files.
