One integration. Dozens of address books.
CloudSponge allows your users to share without ever needing
to remember, type, or upload emails manually.
Instantly integrate with dozens of address books
We support Gmail, Outlook.com, Yahoo and dozens more.
Absurdly easy install
Deploy in minutes, not weeks.
100% maintenance-free for you
Dedicated monitoring and support since 2010.
Secure, private, and fully compliant
Audited and approved to stringent standards.
Because everybody hates manually adding their contacts.
None of the top referral, e-card, e-vite, or fundraising platforms make users type in emails or mess with CSV files.
Add our Address Book Widget to your recipient form and allow users to search, select and share contacts without leaving your website.Try It With My Address Book
Risk-free: your contacts will not be saved or emailed.
Because building it yourself doesn’t make any sense.
You could invest hours learning dozens of APIs and CSV formats, digging through docs, and chewing through spaghetti code…
…then play “integration whack-a-mole” every time something breaks.
Or, deploy our Address Book Widget today, go to market faster, and focus on building what users want – without ever worrying about address book integrations again.
How often do we make fixes and updates? See for yourself in our changelog.
If we were to build and maintain this technology on our own, it would likely cost us roughly 30 to 50 times the cost of using CloudSponge.
Because the ROI is massive
Here’s what happens when users don’t have to type, remember, or manually upload addresses to import their contacts…
Because security and privacy are too important to risk.
Your customers and their contacts are critical to your business. We take that extremely seriously.
That’s why contacts are never saved to disk.
And why we’ve implemented stringent physical, operational, and software security measures that have passed dozens of audits.Review Our Security Measures
