Instead of using Facebook connect with pop ups and Twitter connect (asking to authorize app) you can choose to have "Email Only" as the entry method into your campaign. 

To make it more secure you can "Require users to solve a CAPTCHA"

To choose email only to enter, follow these steps:

  • Login to Wishpond
  • Go to Campaigns
  • Click your Campaign
  • Create your campaign
  • In step 2 choose your entry method as "Email Only"
  • Click "next" at the bottom to save & publish
