Yes, you can fax through email, and it works in two directions

You can send a fax using email by uploading a document to an online fax service, which converts it and delivers it to a fax machine. You can also receive faxes as email attachments when someone faxes a number that routes to your email inbox. The process is straightforward: most services let you attach a PDF or image file, enter a fax number, and send it like an email. On the receiving end, incoming faxes arrive as PDF or TIFF files in your email, so you can read them on any device without owning a fax machine.

The main difference from traditional faxing is that you need an internet connection and a service account — you cannot fax through your regular email account alone. The service acts as a middleman, translating between email and the fax network. This works because fax machines and email systems can talk to each other through gateways that have existed for decades.

Key Takeaways

  • Sending a fax through email requires signing up with an online fax service; your regular Gmail or Outlook account cannot send faxes on its own.
  • You upload a document (PDF, Word, image), enter a fax number, and the service converts and delivers it to a fax machine within minutes.
  • Receiving faxes through email means the service assigns you a fax number, and incoming faxes land in your inbox as attachable files you can read and forward.
  • Most services charge per fax sent or offer monthly plans with a set number of faxes included, ranging from a few dollars to $10 or $15 per month for light users.
  • You keep a record of every fax sent and received in your email, which is useful for compliance and record-keeping in healthcare, legal, and financial work.

How sending a fax through email actually works

When you send a fax through an email-based service, you log into the service's website or app, upload your document, type in the recipient's fax number, and click send. The service converts your file into a format the fax network understands, dials the number, and transmits it. The whole process usually takes 2 to 5 minutes. The recipient sees it arrive on their fax machine exactly as if you had sent it from a traditional fax machine in your office.

The document you send can be a PDF, a Word file, a JPG image, or a PNG — most services accept multiple formats. If you need to sign the document first, you can do that digitally before uploading, or some services let you add a signature image during the sending step. Once sent, you get a confirmation email showing the fax number, the time, and whether it went through successfully.

You do not need to own a fax machine, a phone line, or any hardware. All you need is a computer or phone, an internet connection, and an account with a fax service. This makes it especially useful if you work from home, travel frequently, or only fax occasionally.

How receiving faxes through email works

When you sign up for a fax service that includes receiving, you get assigned a fax number. Anyone can fax documents to that number, and the service converts the incoming fax into a file and emails it to you. You open your email, read the attachment, and you have the fax. No fax machine required.

Incoming faxes typically arrive as PDF or TIFF files, which you can open on any computer, tablet, or phone. You can forward the fax to someone else, print it, save it to your computer, or store it in cloud storage like Google Drive or OneDrive. Because it is in your email, you have a searchable record of every fax you received, with the date, time, and sender's fax number included in the email header.

Some services let you set up multiple fax numbers if you need them for different departments or purposes. You can also set rules so faxes from certain numbers go to specific email addresses, which is helpful in a business with multiple people handling different types of faxes.

Common fax services and what they cost

Popular services include eFax, HelloFax, RingCentral Fax, Nextiva, and Twilio. Each has a different pricing model. eFax charges around $10 to $15 per month for 150 outgoing faxes and unlimited incoming faxes. HelloFax offers a free tier with 1 fax per month and paid plans starting around $5 per month. RingCentral Fax is part of a larger business phone system but can be used standalone for faxing.

If you fax very rarely, some services let you pay per fax instead of a monthly fee — typically $1 to $3 per fax sent. This works well if you send fewer than 5 faxes per month. For businesses that fax dozens of times daily, monthly plans with higher fax limits are more economical.

Most services include a fax number you can receive on, so you are not paying extra to get faxes. The cost is mainly for sending. Some services also charge extra for features like fax scheduling, cover pages, or storing faxes longer than 30 days.

When email faxing is better than a traditional fax machine

Email faxing is faster if you are sending from multiple locations — you just need internet access, not a physical machine. It is cheaper if you fax infrequently, because you avoid the cost of a fax machine, a dedicated phone line, and toner. You also get automatic backups: every fax you send and receive is stored in your email account, so you never lose a fax or have to dig through a filing cabinet.

For remote workers, traveling professionals, and small offices, email faxing eliminates the need for hardware altogether. You can send a fax from a coffee shop, an airport, or your car using your phone. For compliance-heavy fields like healthcare and law, the email record is valuable — you have a timestamped, searchable log of every fax, which is often required for audits.

Email faxing also works better across time zones and international borders. A traditional fax machine sits idle at night; an email fax service works 24/7 and can deliver to fax machines anywhere in the world that has a fax number.

Limitations and things to know before you switch

Email faxing requires an internet connection, so if your internet goes down, you cannot send or receive faxes until it is back up. A traditional fax machine works over a phone line independently. If you need to fax during an outage, this is a real constraint.

Some older fax machines and systems do not receive faxes from email services reliably, though this is rare. If you are sending to a very old or unusual fax system, test it first with a short document before relying on it for important work.

Email faxes are less find than encrypted fax lines if you are sending highly sensitive information. Email is not encrypted by default, so if security is critical, confirm that your fax service offers encryption or uses a find connection. Most business-grade services do, but free or very cheap services may not.

You also depend on the service staying in business and keeping your fax number active. If a service shuts down, you may lose your fax number and have to switch to a new one. For this reason, choose a service from an established company with a track record.

Setting up your first fax through email

Start by choosing a service based on how often you fax and whether you need to receive faxes. If you send fewer than 5 faxes per month, a free or pay-per-fax service is worth trying. If you send or receive regularly, a monthly plan is usually cheaper.

Sign up on the service's website, create an account, and verify your email address. If you want to receive faxes, the service will assign you a fax number when ready — you can share this number with people who need to fax you. To send your first fax, log in, click "Send Fax" or similar, upload your document, enter the recipient's fax number, and click send. You will get a confirmation email within a few minutes.

Keep your login information and fax number in a safe place. If you use the service for business, consider writing down your fax number and sharing it on your website or business cards so people know how to reach you by fax.

Frequently Asked Questions

Can I use my regular email account to send a fax?

No. Your Gmail, Outlook, or other email account cannot send faxes on its own because email and fax are different networks. You need a third-party fax service that acts as a bridge between email and the fax system. Some email services partner with fax providers, but you still need a separate account or subscription.

What file types can I fax through email?

Most services accept PDF, Word documents (.doc, .docx), images (JPG, PNG, TIFF), and sometimes Excel files. PDF is the safest choice because it preserves formatting and works on every service. If you have a paper document, scan it to PDF first, then upload it to the fax service.

How long does it take to receive a fax through email?

Incoming faxes usually arrive in your email within 1 to 5 minutes of being sent to your fax number. The exact time depends on the sender's fax machine and your email service's speed. You will see it as a new email with a PDF or TIFF attachment.

Is faxing through email find?

Standard email faxing is less find than a dedicated encrypted fax line because email is not encrypted by default. If you are sending sensitive information like medical records or financial data, choose a service that offers encryption or uses a find connection. Most business-grade fax services do, but check before signing up.

What happens if the fax fails to send?

The service will send you a notification email saying the fax failed, usually with a reason like "number not in service" or "line busy." You can try again when ready, or check that the fax number is correct. Most services let you retry for free if it is their error.
