How to Send a Fax by Email
Sending a fax by email means composing an ordinary message, attaching your document, and addressing it in a special format that tells the fax service where to deliver. It's the closest thing to faxing from the app you already live in, and it's ideal for people who'd rather not open a separate website every time. Send FAX Mail supports email-to-fax so a document goes out the moment you hit send from your regular inbox.
How does an email turn into a fax?
The fax service gives you an email address pattern that encodes the destination fax number. You put your document as a PDF attachment on a normal email, address it to that pattern, and send; the service receives the email, converts your attachment, and places the fax call to the number embedded in the address. To keep this from being abused, sending is restricted to addresses you've authorized on your account, so a stranger can't fax through your line.
How to send a fax from your email
- 1Set up email-to-fax in your Send FAX Mail account and authorize the email address you'll send from.
- 2Attach your document as a PDF to a new email.
- 3Address the email using the format your account shows — it encodes the recipient's fax number.
- 4Optionally type a short note in the body to appear on the cover page.
- 5Send the email as you normally would.
- 6Watch your inbox for the confirmation reply that reports whether the fax was delivered.
Before you send
Send-by-email only works from an address you've registered, which is a safety feature, not an obstacle — it prevents someone spoofing your account. Attach a PDF for the most predictable result; other attachment types depend on whether your account has document conversion enabled. The subject line and body can populate the cover page, so a clear subject helps the receiving office route the fax to the right person.
Send a fax by email — FAQ
Your account provides the exact pattern, which builds the recipient's fax number into the address so the service knows where to deliver. You attach your PDF, address the message to that pattern, and send — the format is shown in your email-to-fax settings so you can copy it precisely.
No. Email-to-fax accepts messages only from addresses you've authorized on your account, so an unknown sender can't use your line even if they somehow guessed the address. This sender check is what keeps the convenience of emailing a fax from becoming a security hole.
Yes. After the service processes your message it replies to your inbox reporting whether the fax reached the recipient's line, so you have a record without leaving your email. A delivery failure comes back the same way, letting you retry or check the number.
Email-to-fax is part of the paid plans, which start at $12.99/month, because it's tied to your authorized-sender setup and your own account configuration. The 7-day trial covers sending from the website so you can test the service before turning on the email workflow.
