What SendThisFax is
SendThisFax is a paid web and API fax service operated from Paris. Users upload a PDF, enter a recipient fax number, pay, and receive delivery confirmation by email; registration is not required. PDFs may be up to 50 MB and 1,000 pages, but password-protected files are rejected. The service checks destination availability before payment and supports faxing across Europe, North America, and beyond. Most faxes arrive within minutes, with automatic retries when a line is busy. If delivery fails, a full refund is issued automatically, usually appearing within 5–10 business days. The listed Pay per fax plan costs €5 a month as a one-time payment, covers up to five pages, and charges €0.50 per extra page; local VAT may apply. SendThisFax also offers REST API submissions, prepaid-credit API-key sending, and an MCP endpoint for Claude Code, Codex, and other MCP clients. HTTPS, EU hosting, GDPR support, and encrypted transmission are stated. Uploaded documents are deleted after delivery or permanent failure.
