I do this. I have an email address that ends in “.work” for everything, and then a “.mail” which is only for family and very close friends. Signal-to-noise ratio is of course night and day, and I cherish getting something at my .mail account, and have the usual dread for anything on my .work account.

Another small plus: because if the rather unusual format of [myname].[mail|work], spam is virtually eliminated (at least in the .mail account).

I’d recommend it.
