I choose Popfax Online Fax, and I found it cheaper compare with the other fax providers, It matters for me a lot because I work in a marketing company and we send thousands of faxes every month and with Popfax faxmailing options It cost me less than 0.04 EUR per page. They also offered me a free trial, so that I could test their services before signing with them.
I am an Popfax Online Fax costumer and I am happy with them. The service is strictly confidential and reliable, and recently I installed their application on my blackberry. It keeps me updated with all the faxes on the go. I would definitely recommend Popfax to everyone.
Easy for use.
It works fine.
