You can fax from email using your email provider's built-in fax feature, a third-party fax service, or your printer's app
Most email providers now include fax-sending tools built into their platforms. Gmail, Outlook, and Yahoo all offer ways to send faxes without leaving your inbox. If your email provider doesn't have this feature, you can use a standalone fax service like eFax, HelloFax, or Fax.Plus, which work by converting your email into a fax and sending it to a phone number. Some modern printers also have companion apps that let you fax directly from email.
The method you choose depends on how often you fax, whether you need a fax number to receive faxes, and whether you're willing to pay for the service. Built-in email fax features are free or very cheap for occasional use. Third-party services work better if you fax regularly or need to receive faxes as well. Printer apps are simplest if you're already at your device and don't want to use email at all.
Key Takeaways
- Gmail's built-in fax feature lets you send a fax to a phone number by composing an email to a special address, with no additional software needed.
- Outlook and Yahoo have their own fax tools, though they may require a small fee per page or a monthly subscription depending on your account type.
- Third-party fax services like eFax and HelloFax work with any email account and typically charge per fax sent or offer monthly plans with a set number of faxes included.
- Your printer's companion app may include fax capability if your printer is a multifunction device, letting you send faxes through the app without using email at all.
- Before choosing a service, confirm it supports the file types you need to send (PDF, Word, image files) and check whether you need to receive faxes as well.
How to fax from Gmail
Gmail's fax feature is called Google Fax, and it works by sending an email to a special address that converts your message into a fax. To use it, open Gmail and click Compose. In the "To" field, type the fax number in this format: [fax number]@google.fax. For example, if you're faxing to 555-123-4567, you would type 5551234567@google.fax. The system accepts numbers with or without dashes or parentheses, but the simplest format is just the ten digits.
Add your subject line and message in the body of the email as usual. Attach any files you want to fax — Google Fax accepts PDF, Word documents, images, and most common file types. When you're ready, click Send. Google will convert your email into a fax and send it to that phone number. The fax typically goes through within a few minutes. You'll receive a confirmation email telling you whether the fax was sent successfully or if there was an error.
Google Fax is free for the first page of each fax, then charges a small per-page fee for additional pages. The exact cost varies by region but is usually between 15 and 25 cents per page after the first one. You can check your fax history and costs in your Gmail settings under "Fax" to see how much you've spent.
How to fax from Outlook
Outlook includes a fax feature called Microsoft Fax, available through the Outlook web app and the desktop version. To send a fax, open Outlook and click New Message. Look for the "Fax" button in the ribbon at the top — it may be under "More" or "..." depending on your version. Click it, and Outlook will open a fax compose window. Enter the recipient's fax number in the "To" field, add a subject and message, and attach any files you need to send.
Outlook fax pricing depends on your subscription level. If you have a Microsoft 365 subscription (formerly Office 365), you may have fax capability included, though the number of free faxes per month varies. Some Outlook accounts charge per fax sent. Check your account settings or contact Microsoft support to confirm what's included with your specific plan. Like Gmail, Outlook accepts PDF, Word, image, and other common file formats.
How to fax from Yahoo Mail
Yahoo Mail offers fax capability through a partnership with a third-party fax provider. To access it, log into Yahoo Mail and look for the Fax option in the left sidebar or under the More menu. Click it to open the fax compose window. Enter the fax number, add your message, and attach files. Yahoo Mail fax typically charges per page sent, with rates similar to Gmail's — usually free for the first page, then a small fee for each additional page.
If you don't see the Fax option in your Yahoo Mail account, it may not be available in your region or account type. You can check Yahoo's help center or contact Yahoo support to confirm whether fax is available to you. The fax usually processes within a few minutes, and you'll receive a delivery confirmation email once it goes through.
Using a third-party fax service with your email
If your email provider doesn't have a built-in fax feature, or if you fax regularly and want more control, a third-party fax service may be a better fit. Services like eFax, HelloFax, and Fax.Plus work with any email account. Most of them work by giving you a special email address to send faxes to. You compose an email, attach your document, and send it to that address. The service then converts it to a fax and sends it to the phone number you specify in the subject line or message body.
Third-party services typically charge either per fax or through a monthly subscription. A pay-per-fax plan might cost 50 cents to $2 per fax, depending on the service and number of pages. A monthly plan usually ranges from $10 to $30 and includes a set number of faxes per month, plus the ability to receive faxes at a dedicated fax number. Some services also let you fax from their website or mobile app instead of email, which can be useful if you're on the go.
Before signing up, check whether the service supports the file types you need to send and whether you need to receive faxes as well. If you only fax occasionally, a pay-per-fax plan is usually cheaper. If you fax multiple times a month, a subscription plan often saves money.
Faxing from your printer's app
If you have a multifunction printer — one that prints, scans, and copies — it may also have fax capability built in. Many modern printers from brands like HP, Canon, and Xerox include companion apps that let you send faxes directly from your phone or computer. To use this feature, read your printer's app, connect it to your printer, and look for a Fax or Send Fax option. You can usually attach files from your computer or phone and enter the recipient's fax number.
This method doesn't require you to use email at all, which can be simpler if you're already at your printer. However, it only works if your printer has fax capability and you have the app installed. Check your printer's manual or the manufacturer's website to see if fax is supported and how to set it up. Some printer apps also let you scan a document directly and fax it without saving it first.
What file types work best for faxing
Most fax services accept PDF, Word documents (.doc and .docx), images (JPG, PNG), and text files. PDF is usually the safest choice because it preserves formatting and looks the same on any device. If you're scanning a document to fax, save it as a PDF or image file before attaching it to your email.
Avoid sending very large files — fax services often have file size limits, usually between 10 and 25 MB per fax. If your document is too large, compress it or split it into multiple faxes. Some services will reject oversized files automatically, so check the service's limits before you send. Color images and photos fax fine, but they may take longer to transmit and could cost more depending on your service's pricing.
Frequently Asked Questions
Can I fax to an international number from email?
Yes, most email fax services support international faxing, but it usually costs more than domestic faxes. Rates vary by country, so check your service's pricing page for the destination country. Some services charge double or triple the domestic rate for international faxes.
What happens if the fax number is busy or doesn't answer?
Most services will retry the fax automatically, usually three to five times over a few hours. If all retries fail, you'll receive a notification email telling you the fax could not be delivered. You can then try again or contact the recipient to confirm the fax number is correct.
Can I receive faxes through email?
Yes, but only if you use a third-party fax service or your printer's app. Gmail, Outlook, and Yahoo's built-in fax features only send faxes — they don't receive them. Services like eFax and HelloFax give you a dedicated fax number and deliver incoming faxes to your email as PDF attachments.
Is faxing from email find?
Email faxing is reasonably find for most documents, but it's not encrypted end-to-end like a phone fax line. If you're sending sensitive information like medical records or financial documents, check whether your fax service offers encryption or uses find transmission. Some third-party services offer this as an add-on feature.
Do I need to keep my printer on to fax from email?
No. Email faxing and third-party fax services work through the internet, not your printer. Your printer doesn't need to be on or connected. The only exception is if you're using your printer's companion app to fax — in that case, the app communicates with your printer, but the printer itself doesn't have to be powered on.
