A bit of a blackbox from a user's perspective about what it will be they would be receiving beyond "it will be an email" and "it will have an idea".

From the stance of someone who may have just entered their email, before doing so it would be helpful to see an example of what it is we're getting ourselves into.

The pitch is too easily misconstrued to "every few weeks we'll ask you to buy something from one of our advertisers, so please sign up".

Perhaps a friendly use case/sample would be helpful here.
