Fax to email and email to fax
Send FAX Mail connects a fax number to your email, so faxing works in both directions — no machine and no phone line.
Fax to email (receiving)
Every fax sent to your dedicated number is turned into a PDF and delivered straight to your email inbox — the fax-to-email delivery that gives the service its name. A dedicated number is included on the Starter plan at $12.99/month and up. On HIPAA plans the email is a secure link to the document in your dashboard rather than an attachment, so protected health information is never sent in the clear.
Email to fax (sending)
Going the other way, email to fax turns a message into a fax. During the 7-day free trial you send from the dashboard — upload a PDF, Word, or image file and enter the recipient's fax number. On a paid plan you can also send by email: attach your document, address it to the recipient's fax number, and it goes out without opening the app.
