Yes, you can fax to an email address using an online fax service
You can send a fax that arrives in someone's email inbox instead of printing on their fax machine. This works through online fax services — third-party platforms that convert your document into a fax and deliver it as an email attachment or link. The recipient does not need special software or a fax machine; they straightforward receive a PDF or image file in their regular email.
The catch is that the recipient's fax number must be registered with a service that supports email delivery. Most modern fax services do this automatically, but older dedicated fax machines or fax lines may not. If you are sending to a business, their fax number is likely already set up to receive faxes this way. If you are sending to a personal fax line, you will need to confirm the setup first.
Key Takeaways
- Online fax services let you send documents that arrive as email attachments instead of printing on a fax machine.
- The recipient receives a PDF or image file in their email inbox without needing to own a fax machine or install software.
- You need the recipient's fax number, and their fax service must support email delivery — most business fax lines do.
- Services like eFax, Fax.plus, and HelloFax handle the conversion and delivery, and many offer a free tier for occasional use.
How the process works from your end
You upload or scan your document into an online fax service's website or app, enter the recipient's fax number, and send it. The service converts your file into a fax format, dials the fax number, and transmits it. On the receiving end, instead of printing, the fax arrives as an email attachment to the address linked to that fax number.
The whole process takes a few minutes. You do not need a fax machine, a phone line, or any special hardware — just an internet connection and a document in PDF, Word, or image format. Most services let you send from your phone, tablet, or computer.
What the recipient sees
The recipient opens their email and finds a message from the fax service (or from you, depending on the service) with your fax attached as a PDF or image file. They can open it, read it, print it, or forward it like any other email attachment. They do not see a fax machine interface or need to do anything special to receive it.
This is why email-to-fax delivery is useful for recipients who rarely use fax machines but need to receive faxes occasionally. They get the document in a format they already know how to handle.
Services that offer this feature
eFax is one of the largest providers and includes email delivery as standard. Fax.plus and HelloFax both offer free tiers that let you send a limited number of faxes per month. Google Fax (through third-party integrations) and Microsoft 365 (for some business plans) also support fax-to-email. Most of these services charge per fax if you go over the free limit, or offer monthly plans if you send regularly.
Before signing up, check whether the service covers the countries or regions you need. Some services work only within North America, while others support international fax numbers. Read the fine print about whether the recipient's email address is visible to you or kept private by the service.
When email delivery might not work
If the recipient's fax number is connected to an old dedicated fax machine with no email integration, the fax will print on the machine instead of arriving as an email. This is rare in businesses but common in older offices or specialized settings like medical clinics that use standalone fax machines.
You can ask the recipient directly: "What email address should I send your fax to?" If they give you a fax number and say it goes to email, you are good. If they say it prints on a machine, you will need to use a traditional fax service or ask them to set up email delivery with their fax provider.
Cost and free options
Many services offer a free tier: eFax gives you a limited number of free faxes per month, Fax.plus offers a few free faxes, and HelloFax has a free plan with restrictions. If you send faxes rarely, a free tier may cover your needs. If you send more than a handful per month, expect to pay between $5 and $20 per month for a basic plan, or per-fax charges of 25 cents to $1 per page.
Some services bundle fax-to-email with other features like cloud storage, digital signatures, or the ability to receive faxes as well. Compare what you actually need before choosing a plan.
Frequently Asked Questions
Does the recipient need to do anything to receive a fax as an email?
No. If their fax number is set up with a service that supports email delivery, the fax arrives automatically as an email attachment. They do not need to install software, create an account, or change any settings.
Can I send a fax to an email address directly, without using a fax number?
No. Faxes are sent to fax numbers, not email addresses. However, many fax services let you send to a fax number and have it delivered to an email address on the receiving end. If someone gives you only an email address and says they do not have a fax number, you cannot use a fax service — you would send a regular email instead.
What if I send a fax to a number and it does not arrive as an email?
The fax likely printed on a machine instead. Contact the recipient and ask whether their fax line is set up for email delivery. If it is not, ask them to contact their fax provider to enable it, or ask for an email address to send documents to instead.
Is sending a fax to email find?
It is as find as regular email. The fax travels through the service provider's servers and arrives in the recipient's inbox like any other attachment. If you need extra security, look for services that offer encryption or password-protected links instead of direct attachments.
Can I receive faxes as emails too?
Yes. Most online fax services that send faxes to email also let you receive incoming faxes as email attachments. You get a fax number, and any fax sent to that number arrives in your email inbox. This is useful if you want to receive faxes without owning a fax machine.
