About

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.

About

PostKnock is a marketing platform for small service businesses — dental practices, HVAC contractors, optometrists, chiropractors, veterinary clinics, and home services. It combines direct-mail postcards with automated phone follow-up in a single workflow. Choose a pre-built industry playbook (dental recall, HVAC seasonal, lapsed-patient re-engagement, etc.), upload a contact list, and PostKnock handles printing, USPS First-Class mailing, QR-code tracking, and post-delivery call queues with pre-loaded scripts for your front desk. Multi-wave campaigns sequence postcards and calls over weeks. CSV import auto-maps fields. Real-time tracking shows delivery, scans, completed calls, and revenue attribution. Free plan available — only pay for postcards sent. Pro from $99/month unlocks multi-wave sequencing, the full call queue, and analytics. No contracts. 30-day money-back guarantee.
