InTeleSync has the ability to email a message with attachments to a fax machine. With the applicable account permissions, it's as easy as a few simple steps:
To: fax@intelesync.com
From: This needs to be an authorized sender email address on your InTeleSync account
Subject: The 10-digit U.S. fax number to send to
(If you would like to send the body of the email message as a cover page, then enter the words "cover page" in the subject line after the 10-digit fax number. Example Subject: 3862467334 cover page)
Body: Will be ignored, unless you would like to use as a cover page.
Attachment(s): Just about any file type is allowed. All attached files will be converted to a single PDF before sending. The cumulative size of the file attachments cannot exceed 10Mb. That is the limitation of most e-mail servers.
Upon submission you'll receive via email a reply with a confirmation or rejection notice, if requested in your account settings.
