Building on top of the Blacklist/Whitelist Email Domains feature we rolled out a few weeks ago, we've now added the ability to Blacklist/White IP Addresses too.
Blacklist: The blacklist option is to be used to block specific IP Addresses from entering your campaign, and allow all other IP Addresses to enter.
Whitelist: The whitelist option is to be used to allow specific IP Addresses to enter your campaign, and block all other IP Addresses from entering. For example, if you are running a company wide promotion and you only want employees entering while at work, then you would input your company IP Address into the whitelist. The campaign would then only be accessible to those on that IP Address.
