Gladly - You'll be glad you did!
Gladly is a phenomenal company to partner with. Their software is a leader in this space and the team supporting it truly partners with their customers for success. From the sales process, to implementation and even post install support I have always felt like I was the most important customer to Gladly. My guess is all of their customers feel the same way I do!
Gladly is an easy to use, all in one software that allowed us to eliminate multiple, fragmented products we used previously to support our customers. Gladly offers a true 360 degree view of our customers in a UI that is as easy as using a smartphone to text with.
No real cons to report as anything I felt would make my teams experience better on Gladly they implemented shortly after I recommended it.
