Can you fax directly to an email address?

Not directly. Traditional fax signals travel over phone lines and cannot reach an email address without an intermediary. You need an online fax service that converts the fax transmission into a PDF and delivers it to the recipient's email inbox. Services like [mFax.to](https://mfax.to) handle this conversion automatically.

What does the recipient need to receive a fax in their email?

The recipient must have a virtual fax number from an online fax service. When you send a fax to that number, the service converts the transmission into a PDF and forwards it to their email address. Without a virtual fax number, a standard email inbox cannot receive faxes.

Can I send a fax from my email client to a fax number?

Yes. Most online fax services offer an email-to-fax gateway. Compose an email in Gmail or Outlook, enter the recipient's fax number followed by the provider's domain (e.g., 15551234567@send.mfax.io), attach your document, and send. The service converts your email into a fax transmission.

Is faxing to an email address secure?

Yes, when using a reputable online fax service. Providers like mFax.to use TLS encryption in transit. For healthcare or legal documents, look for a provider that offers a signed Business Associate Agreement (BAA) for HIPAA compliance. See our [HIPAA fax guide](/blog/hipaa-compliant-fax/) for details.

What file formats can I fax to an email address?

You can fax any document format supported by your online fax service — typically PDF, DOCX, JPG, PNG, and TIFF. The fax service converts the attachment to a fax-compatible format before transmission. PDF is recommended for the most reliable formatting.
