Easy, Reliable eFax with Smart Features—But Limited Email Password Customization
Reviewed on Jul 17, 2026
Review provided by G2
What do you like best about the product?
What I like best about eFax Online Fax Service is its ease of use and reliability. The user interface is clean and intuitive, making it simple to send, receive, organize, and search faxes without requiring much training. The overall user experience is straightforward whether using the web portal or mobile app.
eFax also integrates well with email, allowing documents to be sent and received directly from an email account, which streamlines workflows and reduces the need for dedicated fax hardware. Integration with cloud storage and document management services further improves productivity.
From a performance standpoint, fax transmission is generally fast and dependable, with delivery confirmations and a searchable archive that make it easy to track important documents.
Compared to maintaining traditional fax machines, phone lines, paper, and toner, eFax offers a good return on investment by reducing operating costs while providing the convenience of secure digital document management.
The onboarding process is straightforward, and customer support resources—including online documentation and support channels—help users get started quickly and resolve issues when they arise.
Finally, eFax has begun incorporating AI-powered features, such as intelligent document handling, OCR (optical character recognition), and workflow automation, which make it easier to search, organize, and manage faxed documents electronically. These capabilities improve efficiency and reduce the amount of manual work required when processing documents.

What do you dislike about the product?
eFAX allows five email addresses to be used on my account. eFAX has the option to password protect documents when faxes are received. Unfortunately, a personalized password assigned to each email address is not possible.
What problems is the product solving and how is that benefiting you?
What is solved is that I don't have to rely on places like Office Depot to send faxes on my behalf. I can do everything at my home at 10 PM.

Essential, Time-Saving Fax Solution
Reviewed on Jun 24, 2026
Review provided by G2
What do you like best about the product?
I love eFax Online Fax Service because it saves me the time of sending by mail and I always receive a confirmation once the eFax is received. It's been the best at-home service, actually saving me money and steps in getting information where it is needed as soon as possible. I appreciate having an ongoing record of all my faxes that are sent, and being able to go back and access that record to resend it at any moment, which I think is the best tool ever! The initial setup was very easy, and I no longer have to go to Staples to send a fax.
What do you dislike about the product?
eFax serves all my purposes.
What problems is the product solving and how is that benefiting you?
eFax Online Fax Service saves me time by confirming faxes are received and keeps an ongoing record, letting me access and resend faxes instantly. It's the best home service that saves me money and steps, providing information quickly where needed.

Online faxing has replaced my fax machine and supports long term document workflows
Reviewed on Jun 21, 2026
Review provided by PeerSpot
What is our primary use case?
How has it helped my organization?
eFax has positively impacted my organization by allowing us to receive faxes since we don't have a fax machine.
This has helped reduce costs by not having to go to a third party at a physical location to receive a fax.
What is most valuable?
In my opinion, the best features eFax offers are that it is easy to use and cost-effective.
From an ease-of-use standpoint, eFax is simple to log in to and receive faxes. I have also used it to send faxes and the interface is simple and browser-based, at least what I use. From a cost-effective standpoint, I haven't compared it to other competitors recently, so I cannot speak to how it compares today versus previously.
What needs improvement?
I don't know how eFax can be improved as nothing comes to mind. It's pretty good the way it is.
For how long have I used the solution?
I have been using eFax for probably ten to fifteen years.
What do I think about the stability of the solution?
eFax is stable.
What do I think about the scalability of the solution?
eFax's scalability is probably fine. I have not had to scale, so I don't really know since I'm a small shop.
How are customer service and support?
I have never used eFax's customer support.
Which solution did I use previously and why did I switch?
I did not previously use a different solution before eFax.
How was the initial setup?
I have been using eFax for a long time, so I honestly don't remember my experience with pricing, setup cost, and licensing. I think it was probably fine and probably pretty easy to set up and run, but I just honestly don't remember.
What was our ROI?
I wouldn't say that I have looked at the ROI at all. It's something we just needed to have, and so we have it.
Which other solutions did I evaluate?
I probably looked at some others before choosing eFax, but again, it's been over ten years, so I don't remember what they were.
What other advice do I have?
I would advise others looking into using eFax to consider it and have a look at it since it's worked great for me. eFax is definitely one of the solutions I would look at if I was searching for a new solution.
I have rated this review a ten out of ten.

Unprofessional Sales Experience Undermined Confidence in eFax
Reviewed on May 19, 2026
Review provided by G2
What do you like best about the product?
……………………………………………………………………………………………………….
What do you dislike about the product?
I own a drug testing and occupational health business, so secure and reliable fax communication is extremely important due to the sensitive personal and medical information we send to and from physicians and other healthcare-related entities.
I contacted eFax regarding an issue and was initially interested in potentially upgrading my service plan. Unfortunately, my experience with Cheyenne was extremely disappointing. She was rude, dismissive, and unwilling to assist me appropriately. I politely requested to be transferred to another salesperson, but instead she repeatedly insisted on transferring me back to support. After requesting again to speak with someone else in sales, she still transferred me to support anyway.
As a business owner, professionalism and customer service matter. The interaction felt disrespectful and unhelpful, especially considering I was exploring expanding my services with the company. This situation should be addressed seriously.

Reviewed on May 18, 2026
Review provided by G2
What do you like best about the product?
What I like most about eFax is the convenience of securely sending and receiving faxes from anywhere without needing a physical fax machine. The platform is easy to use on both desktop and mobile devices, and features like cloud storage, electronic signatures, searchable PDFs, AI-powered document management, and integrations with email and other business applications help streamline workflow efficiency. I also appreciate the reliable document delivery, enhanced security features, and HIPAA-compliant options for managing sensitive information securely.
What do you dislike about the product?
One of the biggest downsides people mention about eFax is the pricing and billing experience. Users frequently complain about expensive monthly plans, extra charges, and difficulty canceling subscriptions. Customer support and the outdated interface also get criticized fairly often.
What problems is the product solving and how is that benefiting you?
eFax addresses the need for outdated physical fax machines when sending important documents. Rather than printing, scanning, and relying on a phone line, I can send faxes directly from email, a desktop computer, or a mobile device.
