Option 1: Split the document – Split the PDF into two parts and send two separate faxes at $3.49 each (total: $6.98).
Option 2: Send everything at once – only $4.99 – Cheaper than two separate faxes! All pages sent in one transmission.

I'm Alexander. I built SendFaxFast for you – because your time is too valuable to waste on clunky tools.
A fax is usually no big deal. But it's often important. And then you just want to know: Did it go through? Did it arrive? Did I do everything right?
That's exactly what you get here. Clear, fast, no open questions. Because I think that's how it should be – and because you don't deserve anything less.
