More text for transparency vs. cleaner design

Question

Topic:
Make user sign up for newsletter in an online fashion shop.

Problem:
I want to be as transparent as possible with the users and not give them the feeling that this is just to grab their data.
The problem is that to be more transparent you have to add more text, which in turn clutters the already somewhat annoying view for the user.

Mockups:
Keep in mind that the text is placeholder like, it will be fine-tuned later. Also, in my country the checkbox text has to be that long, so I kept it that way here.

Dialog with as little text as possible:

Dialog with additional text to make the user less scared of the newsletter:

Question:
Is it favorable to give up some "cleanness" for the sake of transparency? Or maybe the user won't even care at all and only get more annoyed by the additional text.

Answer 1

I think it's preferable to decrease the visual excise by deleting this 3 lines-sentence under the submit button, since it doesn't inform the user that much. What you can do is to combine the first subtitle with your sentence at the bottom, e.g. "by registering for our weekly newsletter" or something in this way.

Answer 2

signing up for newsletters is a tricky thing on the first place. keep it clean and simple, use less words. remove "by registering for our newsletter" and read it again. Ask yourself if you really need it. Do you still understand what you are saying without it? i would also add a "cancel" button. use human language and call it "thanks, not now", "later"

great example of using transparency by specifying the # of newsletters that will be sent + the topics...awesome but would these topics be specific enough to narrow it down or be confusing. will these topics interest your audience or not. overall, it might be too much text for a modal.

let your users sing up and then decide to easily unsubscribe if they choose to.
