how do I stop getting emails

I keep getting a renewal reminder (that I can't unsubscribe from) for a product I never signed up for.

I get it you're a business like any other and I can see the genius in what you're trying to do. 

I already have a few products with GoDaddy so these sorts of practices only ends up leaving a bad taste in the long run. 

So if you can help me fix this I would be greatly appreciative.
