With Uplup, you can easily whitelist or block users in your contest. Why would you need to do this? If a user is marked as spam, but they’re a legitimate entry (a false-positive spam block), you can add them to the Whitelist Users list. This will make it so they bypass the spam filters. Conversely, if you want to block a user, you can add them to the Block Users list.
Step 1.Navigate to Account Settings > Whitelist & Block Users.
Step 2.
From here, you can add user emails to either the Whitelist Users or Block Users list. Click the save button when you’re done!
Note: this will will apply to all campaigns within your brand.
