Very helpful, very kind customer/sales support representative. After speaking with Bettina at Notifyre, I will be signing up for their HIPAA compliant efax service. It is rare to get stellar support without high pressure tactics, and they exceeded my expectations

Excellent Service and Seamless Transition
After facing continuous issues with our previous provider, switching to Notifyre has been a breath of fresh air. We’ve been using their service for about a month now, and the difference is night and day. The platform is incredibly user-friendly, and the setup process was smooth and straightforward. The most impressive aspect of Notifyre is the reliability — no more service interruptions or delivery delays.

Pros: It's easy to use and reliable, consistently working without crashing. Their support team even reached out to me before I started using it, offering help—something very rare in my experience. Kudos to the company!
Cons: None that I found. I used it with Chrome on a Mac, and it worked perfectly.

Great Service and Pay As You Go
Today there are very few situations where a fax is needed. Also, a fax is an additional machine you must keep at home. So having an online fax service makes sense, but most of the services require you to have a monthly subscription, which does not make sense for most of us. Having a pay-as-you-go is the best approach. Also using the web application is very user-friendly

Notifyre is excellent and simple for one-time faxes. The sign up process is simple, and I chose one-time fax. They make you register and add funds starting at $10 that one can use.
