Receiving a fax
Incoming faxes are delivered straight to your email inbox — you'll get an email notification with the fax as an attachment.
A cover page is included only when the email subject contains "cover" (case-insensitive). The cover shows the From / To / Subject / Sent timestamp plus your email body. Without the keyword, only the PDF attachment is faxed.
