CloudSponge is a Contact Picker for all major address books. It allows your users to share their address books without ever needing to remember, type, or upload emails manually.

CloudSponge has been around since 2009 perfecting a product that will help companies get the most out of their existing word-of-mouth sharing feature.

We’ve come a long way from the copy and paste game. We know that once a customer has to leave a site to gather that information, they could leave forever. With the Contact Picker, users have straight access to their entire address books. Sharing contacts becomes a simple click. With straight access to their address books, users are going to share more. That means more site visitors, more referrals, more sales, better open rates, and lower customer acquisition costs.
