What Does It Do?

The DocuSend API allows you to add a menu option or button to “Send US Mail” to your software, making it as simple and efficient as sending an email.

Despite the push for paperless delivery, more than 70% of all transactional communications (bills and statements) last year were delivered by postal mail. That’s over 16 billion documents. Recent data breaches and internet security concerns are reinforcing the consumer’s preference to choose software that offers document senders more distribution choices.Read more.
