Question 1

Can I send a one-time internet fax with no subscription?

Accepted Answer

Yes. Upload a PDF or image, enter the destination number, and pay $0.99 for up to 10 pages. There is no account, no monthly plan, and you are only charged if the fax goes through.

Question 2

What is a single-use fax service?

Accepted Answer

A single-use (pay-per-fax) service lets you send one fax when you need it — IRS forms, clinic paperwork, a signed contract — without signing up for eFax-style monthly billing. SingleFax is built for that: one-time send from $0.99, or a 30-day inbound number if someone needs to fax you back.

Question 3

How does SingleFax work?

Accepted Answer

SingleFax is a simple online fax service. You upload a file (whether it's a PDF, Word document, or an image), enter a fax number, and click send. We convert your file into a fax and send it to the recipient's fax machine. You'll receive a confirmation email once your fax has been successfully sent.

Question 4

How secure is SingleFax?

Accepted Answer

We use bank-grade 256-bit SSL encryption to secure your connection to SingleFax. All your details, including your uploaded files, are sent over an encrypted connection. Your faxes are stored securely and encrypted in your personal dashboard, which you can access anytime via a secure, passwordless magic link sent to your email. You can permanently delete your faxes at any time.

Question 5

Why do I have to pay to send or receive a fax?

Accepted Answer

While some fax services are free, they often come with a catch. They may sell your data, serve you ads, or add their brand as a cover page to your fax. SingleFax does not do any of these things. We don't take any outside funding and are independently owned. We charge a small fee to cover our costs and keep the service running. You're also supporting an independent developer.

Question 6

Is my payment information safe?

Accepted Answer

SingleFax does not have access to your payment information at all. Payments are processed by Stripe, a secure payment processor used by millions of businesses worldwide. Your payment is sent directly to Stripe, and we never see your credit card information.

Question 7

Can I send and receive large faxes?

Accepted Answer

Yes. Retail sends support up to 50 billable pages per fax. Domestic base pricing is $0.99 for up to 10 pages, then about $0.08 per additional page. Destination adjustments may apply. For larger documents, email info@singlefax.com.

Question 8

Can I send a fax by email?

Accepted Answer

Yes. Email a PDF to send@fax.delivery with the fax number in the subject. Same $0.99 pricing — credits send instantly, otherwise we email a payment link. See how email-to-fax works.

Question 9

How much does it cost to send or receive?

Accepted Answer

Sending starts at $0.99 for up to 10 billable pages (then ~$0.08/page, cap 50). A 30-day inbound number is $4.99 (first inbound included; extra inbound faxes $4.99 each). Plans from $9.99/mo or $99/yr. Optional lifetime from $97.

Question 10

When am I charged for sending a fax?

Accepted Answer

We believe you should only pay on success. When you place an order, we place a temporary preauthorization hold on your card. If the fax is successfully delivered, we capture the charge. If delivery fails, we release the hold so you are never charged for a failed fax.

Question 11

Can I get text summaries of my incoming faxes?

Accepted Answer

Yes. SingleFax uses OCR to read incoming faxes and sends a concise text summary directly to your email. Summaries are included for free with your inbound number, so you can quickly scan what arrived without opening the PDF.

Question 12

What happens if I send a fax to the wrong number?

Accepted Answer

Please double-check the fax number before sending. Once a fax is successfully delivered, it cannot be recalled and telecom carrier fees are incurred—so we cannot refund deliveries to the wrong number. Failed deliveries are different: under pay-on-success, we release the preauthorization hold and you are not charged.

Question 13

What happens if the recipient's fax machine is turned off or not working?

Accepted Answer

We retry classified delivery failures up to 4 attempts over ~35 hours (immediately, then 3h / 8h / 24h). Please check your email for status updates and ask the recipient to check their machine. If the fax ultimately cannot be delivered, we release the preauthorization hold—you are only charged when the fax is successfully delivered.

Question 14

Can I get a refund?

Accepted Answer

Because we use a pay-on-success system, you are never charged for a failed fax—if delivery fails, your temporary hold is automatically released. However, once a fax is successfully delivered, telecom carrier fees are immediately incurred. For this reason, we cannot offer refunds if you sent the fax to the wrong number or changed your mind after delivery.
