"Very reliable web service based eFaxing with excellent API"
5/5
What do you like best about Upland InterFAX?

I have been using eFax for many years. Initially my experience was with an on premise eFax server which became a big concern for disaster recovery. Moving to InterFax was very smooth and has been ultra reliable. Review collected by and hosted on G2.com.

What do you dislike about Upland InterFAX?

While it is affordable, faxing is no longer leading edge technology. I think a rate cut is in order. Review collected by and hosted on G2.com.

Response from Ginger Swann of Upland InterFAX

Hi, John. Thank you for your feedback on our pricing. We are constantly evaluating our pricing structure to ensure it remains competitive in the market. We're thrilled to hear how smooth your transition was to cloud from on prem! That's what we aim for!

"Interfax review"
4/5
What do you like best about Upland InterFAX?

We evaluated InterFAX as an alternative to traditional eFax, and found that sending via email was simple and convenient. The ability to track logs was also helpful for audit compliance. Review collected by and hosted on G2.com.

What do you dislike about Upland InterFAX?

However, one drawback was the lack of an automatic retry policy for failed transmissions—users had to manually resend in those cases Review collected by and hosted on G2.com.

Response from Ginger Swann of Upland InterFAX

Thank you for sharing your experience with InterFAX! We're pleased that you found sending via email simple and convenient, and that the ability to track logs was helpful for audit compliance. InterFAX automatically retries three to five times before sending a failed confirmation, so if it's showing up as a failed in your outbound queue, it's already attempted sending three to five times and has not received a successful submission. We decided to limit the retry attempts to 3-5 in order to protect server efficiency. If you're still having an issue with this, please reach out to your Customer Success Manager and we're happy to help!

"Fairly Easy to Use"
3/5
What do you like best about Upland InterFAX?

The interface is clean and basic. Once logged in, I was able to send the fax fairly quickly. Review collected by and hosted on G2.com.

What do you dislike about Upland InterFAX?

The help section is not robust. I really had to dig around to find what a cover page is and how to set up a template. Other than that, this is simple to use. Review collected by and hosted on G2.com.

Response from Ginger Swann of Upland InterFAX

Thank you for sharing your experience. We're pleased to hear that you found our interface easy to use. We understand your feedback about the help section and sent it directly to our product support team. They are assessing the help section to find ways to make it more streamlined and easy to access the information you're looking for.
