There are several customers in our account that we need to block or outright ban from purchasing again.
Is there a way to do this in Nanacast?
Yes, Nanacast supports banning and blocking people from purchasing or signing up to free memberships. You can use the Blacklist feature for this.
From the main menu under Manage >> Blacklist, then click New Blacklist Phrase.
You can block by email address, IP address, or name for all offers, or by state/province for your affiliate program.
