Online faxing is the more modern way of sending faxes. Instead of having to use the big fax machine, users can instead scan their documents with a gadget (either a phone or an actual scanner) and send it online. It can be sent both to another digital fax or through a traditional fax as long as you have their number. This convenience makes it a necessity nowadays for businesses as having to buy a traditional fax machine is expensive and is also hard to maintain as it is prone to experiencing issues.

Features of using online fax services

The main benefit of using an online fax machine is that everything will be done online. The fee for sending messages will be the same no matter where the receiver is. This is unlike the traditional fax machine which charges users per fax that they send when they use a conventional phone line. This means that sending faxes outside of the local calling area of the user will be charged with an extra fee. With online faxing, the fee for connecting to the internet is flat and will no be charged extra even if they send faxes internationally.

Aside from this, they are also easier to use. Newer employees will not need to receive further training about using the technology as it is similar to using e-mail applications. Offices also does not need to install new software or hardware in their offices as online faxes are mostly just easy plug-ins. Some even come in mobile applications. This allows the user to be able to create and send faxes through their mobile phone no matter where they are. This makes it a more convenient choice compared to the traditional fax which may be more complicated to use and is primarily stationary which makes it less convenient.

Lastly, the main benefit of online faxing is the security it provides. With these services, the faxes that you send will be encrypted. In case it will be hacked or accessed by an unauthorized third-party, they will not be able to read its content. This is to be expected given that online faxing works similarly with e-mails. This is unlike traditional faxing machines wherein the fax that you will be sending will not necessarily be received directly by the receiver and may possibly be read by a lot of people.

Their entire service is cloud-based which allow users to have more integration for office applications such as ZenDesk and DropBox.
