5-Minute Growth Hack

Installing our widget takes about 5-minutes. Just paste our snippet in the page and tell us the HTML ID of the “To:” field and you’re done.

We’ll insert a comma-delimited list of email addresses that your users select straight from their address books.

There’s no excuse for making your users manually type or copy/paste their friends’ email addresses anymore.

Get Started

300+ Contacts Per User
The average number of email addresses in one address book is over 300. Need we say more?

Approved Integrations
OAuth2 integrations for popular address books sources, like Gmail, Yahoo Mail, Outlook.com, AOL and many others.

White Labeled
Don’t like the way our widget looks? Then use your own stylesheet and replace our branding with your own.

Integrating CloudSponge was a snap. It makes it easy for our users to invite their friends and family to join Kiva.
