Frequently Asked Questions
Straightforward answers about sending and receiving faxes, plans and refunds, your account, security, and Faxify MCP.
A fax can fail for many reasons. Common causes include:
•
A bad or busy connection to the recipient
•
Wrong or incomplete fax number
•
Recipient line busy, not answering, or dropping the call
•
Line noise or mismatch between fax systems
•
Oversized files or formats we cannot send reliably
•
On physical fax machines: paper jams or full memory
Faxify only sends to numbers in the United States and Canada.
Check the number, wait 15-60 minutes or try again in the evening when fax traffic is often lower, and use the in-app Scanner for paper originals. Online fax can be more reliable than a traditional machine when the network is congested.
Wait and resend after about 15 minutes or an hour, or try again in the evening when lines are often less busy.
If it keeps failing, ask the recipient to check their fax machine or number.
Yes. Open the App Store on your Mac, search for Faxify, install it, and open it like any other Mac app.
Some PDF or image files may not attach. For paper pages, use the in-app Scanner - it usually works best.
For files on your device, convert them to a standard PDF or image with another app if needed, then add them again in Faxify.
Yes. Buy a one-time Fax Pass: $2.99 for a single fax of up to 25 pages, or $4.99 for a single fax of up to 100 pages. A pass never expires and is only spent when your fax is delivered — if it cannot be delivered, the pass comes back. One pass sends one fax; unused pages do not carry over.
You can also send up to 5 pages per month on the free tier (with ads) without subscribing. Fax Passes are available in the Faxify web app and in the iOS and Android apps.

Publish that number on a card or website, often with a local area code when available

Otherwise, about one month after you are on the free tier or go back to free when a paid subscription ends or is canceled.
Yes. In the app, open Settings, use Report an Issue, and ask us to delete all drafts and faxes. Your account and billing history stay on file.

Faxify is online fax for the United States and Canada. Send and receive from iPhone, iPad, Mac, Android, a browser at app.faxify.com, or optionally from AI tools using Faxify MCP. You do not need a fax machine or phone line - only the internet. Attach PDFs, scans, or photos; upgrade to a paid plan when you need more pages or a dedicated number on eligible plans.
Yes. Download from the App Store or Google Play, use https://app.faxify.com in a browser, or connect supported AI tools through Faxify MCP (https://mcp.faxify.com).
Faxify MCP uses the Model Context Protocol so tools like ChatGPT, Claude, and Cursor can talk to Faxify. You can send and receive faxes, search drafts and history, automate repeat jobs (such as invoices or forms), and manage account settings when your setup allows it. Overview: https://mcp.faxify.com. Technical setup: https://github.com/Faxify/mcp-client
No. Faxify only supports fax numbers in the United States and Canada. Other countries are not supported.
We use 256-bit SSL to encrypt data between your device and our service. Protect your account with a strong password and device security, especially for sensitive legal, medical, or financial documents.
No. Faxify is not HIPAA compliant and does not sign Business Associate Agreements. Do not send PHI (Protected Health Information) through Faxify.
This applies to every plan, free and paid — there is no HIPAA tier. Faxify's carrier and storage providers hold their own BAAs with Faxify; those cover their relationship with us and extend no HIPAA coverage to you. If your workflow involves PHI, choose a vendor that will sign a BAA with you.
Send up to 5 pages per month on the free tier (with ads). No credit card is required. See https://www.faxify.com/en/pricing for current plans.
PDFs; images such as JPEG, PNG, TIFF, SVG, and WebP; and Microsoft Office files (DOC, DOCX, PPT, PPTX, XLS, XLSX). For paper originals, use the in-app Scanner. If a file fails to attach, convert it to PDF or a common image with another app, then try again.
Open Sent in the app to see progress and a final status. We show delivered only when the fax reaches the recipient, not merely when the file reaches our servers (some other apps label that as "sent"). Received faxes appear there too. With Faxify MCP you can also check status and search history from a connected AI tool.
Yes, through Faxify MCP. Connect your AI tool, then use natural language to send or look up faxes and automate workflows where your integration supports it. Start at https://mcp.faxify.com
Individuals: send a fax from chat (for example, "Fax this PDF to 555-123-4567") or ask for recent inbound faxes. Businesses: tie faxes into CRM or document systems, or trigger sends from back-office automation. Developers: build assistants and scheduled sends (invoices, contracts, reports) on top of MCP. Exact features depend on your AI product and configuration.
Configure the Faxify MCP server for your AI client. Product overview: https://mcp.faxify.com. Setup, auth examples, and code: https://github.com/Faxify/mcp-client. After setup, use normal language in the AI tool to drive allowed Faxify actions.
MCP is for automation and AI workflows: recurring sends, search by natural language, hooks into other tools you use with your AI stack, and custom agents where you build them. Day-to-day manual faxing stays in the mobile or web app.
Connections use the same 256-bit SSL approach as the main app, with user checks before actions run. You should still follow good security practice for API keys, AI accounts, and sensitive documents.
