I agree on "they" but not "theM". Also I would only use "they" when talking about some generic person that really doesn't have a specific gender (or any other specific characteristics). If I'm writing an email about my investor I know who that is and what gender they are. Getting "them" as completion option is almost never what I would wan't in that case. (Above I even used "they" subconsciously, because It was just an example and I don't actually have an investor to talk about here.)
