I'm sorry, I'm a beginner in Drupal 7, and I don't really understand the roles behaviors. I arrive in a website which is already done, and I have to add a functionality : a newsletter for another entreprise but on that website.
So I used Mailchimp to create a list, and the subscription is possible on the website. But I don't really understand how to send a mass contact to these people because they're not put in a specific role.
So my question is, how can I put people who subscribe to this newsletter in a specific role (Which I already created) ?
I'm sorry, maybe this is a bit difficult to understand, and there can be a lot of mistakes in my message because I'm French.
I read some of the answers in that website and I looked for some others on the internet, but really, it's extremly complicated, I don't even know where to put those php codes I found.
Thank you really much for reading it, if you can help me, I would really be pleased !
