It's a simple tool and pretty effective. Super stable and trustful. The only problem is the pricing, since there are cheaper tools in the market.

It's a great tool that allows to centralize much of the marketer needs: Landing page creation, database management and email marketing. The only problem I see is that it's a little bit complicated to remove inactive contacts correctly. And, since they charge you for the list size, you have to be cautious about the costs.
