Comentários: Good, but could be better, especially regarding the email marketing tool.
Vantagens: Mapp allows you to connect, visualize, filter data and use that data to create audiences and marketing campaigns, all within one single platform. It's a great tool to do that if you don't have database management staff in your company, and even if you have, you can use its advanced API to automate some of the more tedious tasks.
Desvantagens: The email marketing/HTML creator has some bugs and won't interpret code correctly sometimes. The templates not usually work in a responsive manner, so sometimes you have to manually tweak it so it works on every type of screen and email provider.
