    eFax: Reliable and Easy Solution for Healthcare Communication

    Reviewed on Jul 28, 2026
    Review provided by G2
    What do you like best about the product?
    I use eFax Online Fax Service to communicate with different health care providers, which is extremely helpful as a therapist. eFax solves the communication problem compared to traditional fax machines because it's very efficient, letting me know clearly if the fax is sent without any wondering. I like the reliability because it's convenient, sending notifications to my eFax account and email for incoming faxes. Compared to a traditional fax machine, eFax's reliability is 10 out of 10, so I'm confident the fax has gone through. The convenience of not having to check if a fax was sent saves me time, as I know every fax went through when eFax confirms it. The value is wonderful at $20 a month, guaranteeing sent faxes are received and I get notified in two ways. eFax is super easy to set up and anyone with minimal computer knowledge can create an account by signing up with an email and password. I highly recommend eFax service anytime, especially for providers struggling with sending or receiving faxes.
    What do you dislike about the product?
    There is nothing I don't love about this product!
    What problems is the product solving and how is that benefiting you?
    I use eFax Online Fax Service to ensure smooth communication with healthcare providers. It solves issues I had with traditional fax machines. It's reliable and convenient, saving me time and confirming sent faxes without needing follow-up calls.

    Streamlined Faxing with User-Friendly Interface

    I like the option to send faxes via email using eFax Online Fax Service. It's has a user-friendly interface that's easy to navigate. I also appreciate the security features and overall ease of use it offers. The initial setup was pretty easy, and the transition from Fax Zero to eFax made handling faxes much simpler.
    What do you dislike about the product?
    I find it takes a while for the fax to appear in my sent items after being sent. It doesn't show up right away.
    What problems is the product solving and how is that benefiting you?
    I use eFax Online Fax Service to fax documents to different organizations. I like that I can send faxes via email and enjoy its user-friendly interface and security. It made faxing easier and reduced the need to physically go to a store to send faxes.

    Minimalist, Reliable Faxing with Smooth Workflow Integration

    Reviewed on Jul 28, 2026
    Review provided by G2
    What do you like best about the product?
    eFax is a minimalist, no-nonsense platform for sending faxes when required, whether for business, PHI, or personal use. I have used it frequently for transmitting forms while keeping sensitive information separate from my email when possible. The UI makes it simple to add a file, cover letter, and basic contact information for form transmission. The eFax app integrates well with several workflows requiring receiving forms and transmitting them after completion. When forms are sent via mail, efax makes it possible to send over PDFs that were freshly scanned via Google Drive. I haven't experienced any major issues regarding speed, and feedback from the app is responsive. $9.99 is reasonable for an app that provides faxing services. The application interface is straightforward enough that minimal support is needed to send faxes when required, only requiring an email addres and a valid credit card before a fax can be sent. Given the heavy emphasis on AI in today's tech, I believe that it is a benefit that AI isn't heavily integrated within eFax services.
    What do you dislike about the product?
    Periodically, it is slightly difficult to determine what may have failed in a request transmission, or when a fax is pending, specifically what was written. I believe that having some degree of persistent feedback in fax transmission could ease this potential pain point. AI could potentially be implemented with a minimal footprint to determine whether two fax messages are sufficiently similar to warrant notifying the user before transmission while the other is pending (as opposed to having never ben sent).
    What problems is the product solving and how is that benefiting you?
    eFax helps tremendously in the process of medical health form completion, especially those involving time-sensitive content. After logging on, I can quickly use the UI to transmit a simple message containing the contact, a cover letter for the fax, and the relevant form without significant performance bottlenecks.

    Fast, Intuitive Online Faxing That Saves Hours

    Reviewed on Jul 27, 2026
    Review provided by G2
    What do you like best about the product?
    I like how easy it is to send faxes online—it only takes me a few seconds from scanning the documents to sending them to any number I need. I also find it simple to delete faxes from my inbox, since the UI is very intuitive. Overall, it has saved me hours compared with our old fax machine, where I had to scan pages one by one. We have integrated this into our daily use to attend to customer demands and for the price we haven't found any reason to complain. Support is also readily available whenever we need it.
    What do you dislike about the product?
    I dislike the feature that requires me to type in contact information for a fax number as it is not always to a person but sometimes to a company where there is no name to address it to.
    What problems is the product solving and how is that benefiting you?
    It is solving the problem that there is now a lack of telephone lines across the US making traditional fax machines less useful and requiring people to adapt to newer technology
