Hello Zohra,
By looking into to documentation of the module https://marketplace.mendix.com/link/component/1296 you have a tab called Documentation, which will guide you to a step by step.
In your case, the problem is that the module has dependencies with another module and it's trying to find in your project those modules.
You will need to download the other modules of the dependencies, in this case the email module and once you download it into your project it should fix those errors automatically.
Please pay attention in this part of the documentation:
Hope it helps,
Rui Cunha
