Yes, FREE, no hidden fees or risks.
To get started you simply need to be on a computer that is currently connected to the internet. You most likely already have this in front of you so the next step is to sign up or start a free trial with an online fax service that offers a Google fax solution and easy integration.
If you don't like the service simply cancel before your 30 day trial is over. Why use a free trial instead of a website that offers to send a free fax? If you are in a search of a safe and reliable faxing solution at an affordable price (you can find plans as low as $1 a month), then online faxing is the best option.
If you simply need to send a quick and non-confidential or professional fax then using "free fax" websites is ok, but keep in mind that these services offer no guarantee to deliver your fax on time and you cannot receive faxes, much less get a free fax number (like you would with online fax).
There are many great email fax providers but not all of them offer easy integration with web mail. You can fax from any web mail, including Gmail, Hotmail, Yahoo and others.
Getting started is easy because you don't need any previous experience with email fax. Sending a fax via email is very similar to sending a regular email. The difference is that you will be sending the email to fax. You can also receive faxes to your email fax account.
