Data Storage - Email Messages - Any advice on reducing impact

Hi

I am looking for some advice on how other Users are handling Email Messages in their Orgs.

Our Data Storage is at 70% and 79% of that is Email Messages.

I wonder if there is a better way to handle the storage of these.

I read an article whereby someone remove the HTML and Text Body fields and puts them into separate custom fields. This seems a tremendous amount of effort and I am keen to understand other Users' experiences
