DocuSend
Remotely send your documents directly to the United States Postal Service through our cloud-based mailroom. DocuSend works with any accounting, billing, or CRM software that produces PDF documents containing a valid mailing address. Users can upload directly, or developers can integrate our REST API to offer a "Send Mail" button in their software, either as a reseller or for internal direct connectivity. There are enormous economic advantages for any business or organization that needs to safely print and mail documents on demand. We also offer an automated email service called DocuLink that lets you know which users open the document links sent and makes it easy to follow up with a hard copy if needed. We are sure that one of our features will improve your mailing experience: DocuSend, DocuLink or the Print-To-Mail Rest API will streamline the manual and time-consuming print, mail and email process.
