eFax offers its users a secure, online alternative to traditional fax machines. For industries that are reliant on faxing for secure or legal documents, with eFax all faxes are sent via encryption. When you receive a fax from eFax, you are sent a notification email that contains a unique URL. This then takes you to the eFax account login where a secure sockets layer (SSL) connection is made.

There are also choices in how you choose to send your faxes, from an app you can download to seamless integration with your web browser. You can even choose to send a fax directly from your email account.

eFax review: Design and usability

  • No software to download
  • Web or email based and also has an app service

There are a number of ways to send a fax – via email, your eFax account and the app. To send a fax via email, users need to create an email and in the address field send it to the fax number followed by the eFax link. For sending eFaxes internationally you do not need to include the international dialing prefix, only the city and county codes are needed. You then attach the document that you want to fax.

If you do not have access to your email, but want to send documents from your computer you can send a fax via your eFax account online. You will fill out a web form and then attach any documents you want to send, via a browser button on the form. Once the files are attached you click send. 

If you want to send, receive and or sign a fax using the mobile app you open up the app on your device and choose what you want to do, fill in the boxes, attach documents if you have them saved on your device and send. Once the fax is sent the recipient will receive their fax on their machine and will not know if it has been composed using the online account, email and or mobile app.

eFax review: Performance

  • Wide range of file compatibility
  • Option to have a single fax number or multiple ones

With eFax, you can attach up to four documents and they will be faxed in chronological order. eFax supports most document types from Microsoft DOC and DOCX to PDF or image files such as TIF and JPG. Excel documents (XLS) and HTML are also supported. 

Something to bear in mind is that eFax does not support password protected files. Once you are happy that you have attached all the documents then you hit send. This can also include a cover page and what’s more, all templates will be provided by eFax. 

Once a fax is sent, it will take a few minutes for a transmission receipt to be received via email. The receipt will give details of the page count and total transmission time. If the fax does fail to send, you will be given a reason as to why it failed.
