Email Contact Importing for E-Commerce Websites

Your registration list could grow from a few to a few hundred.

Grow your attendance and get attendees to refer their friends, family, and colleagues by giving them access to their contacts while on your website. CloudSponge is the simplest way to get users send incentives to their friends to register for events, facilitate deeper connections with other users in their address book, and build community faster.

Gain access to more potential attendees. Email address books contain an average of 350 email contacts.


Immediately integrate with over 30 popular email providers like Google, Outlook, and Yahoo.


Keep users who want to refer friends or colleagues to events from leaving your site to look up their friends’ email addresses. Our widget keeps them in their browser, on your site, focused on selecting friends for referrals.


Your users’ data is safe: We purge every email address that passes through our system after it’s delivered to our client. So far we’ve wiped over 4 billion (with a B) email addresses.

How Event Companies Use CloudSponge
