    What do you like best about the product?
    eFax performs really well by saving both received and sent faxes for later review. This is a big plus when I need to research something at a later date. The pricing is fair, and support is better than ever. With the use of AI, sending faxes has become easier, and the integration process is straightforward. The UI is also great.

    eFax has become much easier and I find no difficulties any longer.

    I have had eFax since early 2000's.

    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.

    What do you dislike about the product?
    Every once in a while, I'll try to send a fax and it says there's an error, but it doesn't tell me what the error is. So I don't know how to correct it or fix it.

    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?

    My main use case for eFax is receiving faxes.

    A specific example of a situation where I used eFax to receive a fax is a copy of a contract being sent to me.

    I also use eFax to receive copies of my EIN from the IRS and other documents from the IRS.

    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

    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.
    What problems is the product solving and how is that benefiting you?
    This does not matter when customer service is poor.

    eFax simplifies secure, professional, remote-friendly faxing with AI-powered efficient

    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.

    Easy Fax Routing with Helpful Folders and Multi-User Email Support

    Reviewed on Apr 14, 2026
    Review provided by G2
    What do you like best about the product?
    I like that it’s easy to route forms and information to where they need to go. At my organization, we appreciate being able to use different user emails, which helps us differentiate who sent what and who is receiving what. I also like the folder feature, since it helps me sort what’s specific to my role versus my coworkers’ roles.
    What do you dislike about the product?
    I dislike the fax preview feature. Because the preview is typically just a generic confidential cover page, I still have to open every single fax and then mark it as unread if it doesn’t pertain to me. I also dislike that I can’t download fax confirmations to add to employee files as proof/documentation for critical items. As far as performance goes, the main issue for me is the bugginess when viewing faxes. My system often glitches in and out when I’m trying to open new faxes, mark them read/unread, or move them to a different folder.
    What problems is the product solving and how is that benefiting you?
    eFax Online is helping us save on fax costs. By using eFax, we’ve been able to reduce the expenses tied to paper faxes and using a manual printer. Moreover, eFax provides a solid, centralized hub for our HR team to work from.

    I like the simplicity of eFax Online Fax Service, and how easily manageable it is. The ability to sort faxes into folders is really helpful, as it allows others to quickly view folders to find legitimate faxes from random ones. Assigning tabs also helps. Additionally, the initial setup was very simple.

    It would be helpful if eFax Online Fax Service could identify spam faxes and have a designated folder for such.
    What problems is the product solving and how is that benefiting you?
    I use eFax Online Fax Service to receive referrals and clinical authorizations. Its simplicity and folder organization make it easy to manage and sort faxes, helping others quickly find legitimate ones among random faxes.
