This is such a poorly designed, hacked together “thing” – it isn’t a database, it’s someone’s idea of how to store data when they don’t know how to store data, like they moved it from Access or Excel.
Just start over and design a proper relational schema with best practices and you’ll save, oh, perhaps 10 years of wasted effort and 12 million emails. This is as close to bandaids on bandaids on steroids that it comes. Really – rethink your solution model.
