Very Helpful Support
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

Great Service
The CEO of Notifyre contacted me directly after my initial review. Within a 2-hour window no less. I never requested for anyone to contact me, yet he did - credit where credit is due; I appreciate it.

Personalized 10DLC Assistance
The Notifyre folks made it simple to go through the 10DLC registration process so we could start sending SMS messages to our patients. They provided the personal service that was lacking from other services we had explored and that made all the difference.
