I do this too, I just forward ALL my mail into my personal gmail (which I don't usually give to anyone) and label it differently, and have them all set up to "Send mail as" from gmail. Email Deliverability is great (atleast to other gmail users, since the mail comes from gmail servers). I don't like the idea of checking multiple mail accounts, and setting up a couple filters goes a long way in organization. and It costs me nothing. And in case my gmail gets suspended, I can easily switch to another service. As for privacy, I don't really think mail should be used for any communication that can come bite you in future.
