Tame your newsletters!

So I'm at a point where I have subscribed to a lot of newsletters, different topics newsletters that I read in relation to my work life and habits. I use G-mail and I've had to create different email accounts just to try and control this flow, with no success however.
So it hit me, Maybe I should consider building a tool to help me control,filter and remind me about my newsletters.
Here's the thinking behind the idea:
• There's too much content that it's a destruction so I would like for a very minimal solution that takes me to the point.
• I want to be able to create categories or sections for filtering incoming newsletters
• I would like for the solution to read my preferences and put them at a higher priority.
• I don't want to be able to save for reading later or anything along those lines, I find that it adds up to procrastination.

So I googled for similar solutions found nothing I could rely on. Also a fellow IH posted something like this and I said I'd jump on it. Validation so far is little to none.
Please just let me know what you think about this. Do you think it's something :
• worth building
• worth paying for
• something you see yourself using.
Any comments would be highly appreciated.
