At first I found it difficult to adapt to the way it has to filter the lists and create campaigns through segments, but once I overcame that barrier I find it very flexible and effective. The rest of the functionalities are very good, and it is very easy to use. I have yet to test the creation of an agency account and I think it is very good that it is separate from the white label. Very good product, just to say that this is the fourth time I buy it, the previous ones were purchases made directly from my own accounts in Appsumo of my clients.
