"Sending Faxes Has Never Been Easier User"
5/5
What do you like best about InterFAX?

Sending a fax has never been easier. There's no need for printing or handwriting on documents, waiting by the dial pad to ensure it went through, or wasting paper. It's also incredibly simple to access the history of the documents I've sent. There is no training required; it's very user-friendly and easy to navigate. The pricing is comparable to what you would expect for using a regular fax service. Review collected by and hosted on G2.com.

What do you dislike about InterFAX?

One thing I would like is the ability to view the documents that have been sent at any time. Review collected by and hosted on G2.com.

Response from Ginger Swann of Upland InterFAX

Your feedback about document visibility is valuable, and we will strive to address this in our future updates. We really appreciate you taking the time to leave such an insightful review!

"User-Friendly Fax Solution with Room for Improvement"
4.5/5
What do you like best about InterFAX?

I use Upland InterFAX mostly for sending and receiving fax, and I like that all faxes are in one place. It's pretty user-friendly and straightforward for our purposes, making it easy to use. We often attach files to nearly every fax we send, which is something I value a lot. The initial setup was fairly easy and didn't take much time at all, which I appreciated. Review collected by and hosted on G2.com.

What do you dislike about InterFAX?

I often find that too many or perhaps too large files appear to be uploaded and attached, but then the transmission fails. We've had to send multiple faxes to accommodate many uploaded files so that it can be sent successfully. Also, whenever any fax fails to send, we do not get any notification about this, so we can't attempt to resend it. We have had to try to get in the habit of checking the outbound fax list to ensure that faxes have indeed been sent, but this reduces the program's efficiency and takes up necessary time. Review collected by and hosted on G2.com.

Response from Ginger Swann of Upland InterFAX

Thank you for highlighting the benefits of Upland InterFAX in centralizing your faxes and providing a user-friendly experience. We will work on addressing the notification and transmission issues to further improve the platform.

"Convenient, Reliable, Timeless - Faxing For Freedom, the Criminal Defense Lawyer's #1 Fax"
5/5
What do you like best about InterFAX?

It's been a convenient and reliable service for me. I've been using it for almost 15 years and have never had a complaint about it. The ability to send and receive faxes is something a lot of lawyers don't have anymore but I believe that it a fax lends an aura of gravity that an email does not. Review collected by and hosted on G2.com.

What do you dislike about InterFAX?

Initially I did not like the interface - it seemed a little clunky and outdated when I started using it in 2011 or 2012, but now that it's grown on me I realize that this is not a bug but a feature. What I thought was "outdated" was really timeless and reliable. I can't imagine any changes I would make to anything. Review collected by and hosted on G2.com.

Response from Ginger Swann of Upland InterFAX

Thanks, Joseph! We're thrilled to hear that Upland InterFAX has been a convenient and reliable service for you for almost 15 years. We understand the importance of being able to send and receive faxes, especially in the legal field. We really appreciate your feedback!

4.5/5
What do you like best about InterFAX?

What I like most about Upland InterFAX is how easy it makes something that's traditionally a hassle.

It's a simple, reliable solution that just fits into your workflow. Review collected by and hosted on G2.com.
