FAXAGE vs Sinch Fax API

FAXAGE provides Internet faxing through email, a website, mobile apps, and an API. The web interface sends and receives faxes, with received documents downloadable as PDFs; incoming faxes can also arrive by email as PDFs. Email-to-fax sends to machines in the United States and Canada. Mobile apps import files from iCloud Drive, Google Drive, and Dropbox, then share through Slack, Skype, WhatsApp, and Trello. Its API handles sending and receiving, DID provisioning and control, call-detail records, real-time status, notifications, user management, and audit-log retrieval. Security features include TLS/SSL, PGP, AES-encrypted PDF passwords, per-user controls, and system auditing. FAXAGE says its in-scope facilities and platforms have HITRUST Certification and can support HIPAA, SOX, and GLB requirements. Plans are billed monthly per line, starting with Lite at $3.49 a month plus a 5.00 USD setup fee and 0.05 USD overage per minute. Accounts include unlimited users, authorized email addresses, and online fax storage.

Sinch Fax API is a cloud service for sending and receiving faxes through a REST API. It supports delivery tracking and webhooks for incoming or completed faxes, with Basic or OAuth 2 authentication. If storage is enabled, fax logs and media remain available for 13 months before deletion. Listed formats include DOC, DOCX, PDF, TIF, JPG, TXT, PNG, URLs, and HTML. A customer portal shows fax status and send or receive times, and provides controls for users, groups, roles, and permissions. Sinch describes intelligent routing and automatic retries for failed transmissions, and says its U.S. fax-processing network has 99.999% uptime and redundant infrastructure. Customers can select local or toll-free numbers or bring their own; the infrastructure is described as scalable for high volumes. The service supports stated HIPAA, SOC 2, and GDPR compliance needs and secure transmission for healthcare data. A free Sinch Build Dashboard account is required to start, and signup includes a free virtual number for testing. Pay-as-you-go costs $0.05.
