Our verdict on Send FAX Mail API
Send FAX Mail API is a JSON REST API for adding fax transmission to business software. It supports outbound fax submission, delivery-status retrieval, fax listing, dedicated-number lookup, scoped bearer keys, idempotent requests, and signed webhook events. The product also supports receiving faxes, fax-to-email delivery, dedicated fax numbers, and online faxing, making it a fit for developers building fax workflows for healthcare practices, law firms, finance teams, and other businesses.
The paid plans separate general faxing from API access. Starter costs $12.99 per month and includes sending and receiving faxes, fax-to-email delivery, and fax history and downloads. Professional costs $39.99 per month and adds HIPAA compliance, a self-serve BAA, document signing before sending, and priority delivery. Business costs $79.99 per month and adds the public API, webhooks, audit logs, team roles and permissions, and priority support. Enterprise costs $169.99 per month and adds signed webhooks, dedicated support, and custom integrations. A 7-day free trial is available, while the published plans show 600 included pages.
For developers, the API's strongest area is operational control: POST-based fax submission, status and page-count retrieval, pagination, scoped keys, idempotency, scheduled sending, and events for delivered, failed, and received faxes. That combination suits applications where timing and delivery visibility matter. The tradeoff is a narrow platform footprint and plan gating: the API is available on Business and Enterprise, while lower tiers focus on web-based faxing. Choose Send FAX Mail when scheduled sending and webhook-driven workflows are central; consider another option when broader platform or integration coverage is the priority.
