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

    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 Customer support and the outdated interface also get criticized fairly often.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    eFax addresses the need for outdated physical fax machines when sending important documents.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.

    Review provided by G2
    What do you like best about the product?
    I like eFax Online Fax Service for its speed and accuracy, along with its availability. The user-friendly inbox makes it easy to see everything in one spot, which is perfect for our needs at a small law firm. I also love that I can fax directly from my email, specifically from Outlook, which adds a lot of convenience for outgoing faxes. The feature of being able to fax hundreds of pages electronically solves the problem of fax size for us.
    What do you dislike about the product?
    I don't like that I have to go through a few steps to preview an incoming fax prior to downloading. I wish there was a preview in the inbox without downloading.
    What problems is the product solving and how is that benefiting you?
    eFax Online Fax Service allows me to fax hundreds of pages electronically, offering speed, accuracy, and availability. It's user-friendly, and I love faxing directly from my email with everything visible in one spot.

    I like that I can see fax history from years ago with eFax Online Fax Service. This feature is great for keeping records in case I ever lose the physical copy. I also find the initial setup to be pretty easy. I called customer support a while ago, and they helped me quickly.
    What do you dislike about the product?
