How does FreshAddress have such a large email database?
We source our proprietary data through 1) our own consumer email change of address website, and 2) licenses with hundreds of consumer websites such as mortgage sites, travel sites, gaming sites, free email sites, etc. All FreshAddress data is 100% opted-in (volunteered) information, with date/time/source stamp. In addition to our own proprietary data, we source supplemental data from our carefully-screened data partners.
