Having abandoned Apple’s Mail App long ago, I have used several third party Email Apps over the years. One those is the Postbox Email App. If you are a light Email user, then Postbox is not for you. But, if you are an Intermediate or Power Email user, then you should give serious consideration to the very powerful Postbox 7 App. This article describes all that Postbox 7 can do and it is plenty. The only drawback as far as I am concerned is its subscription model, but if Email is a main part of your workflow I don’t think that is a deal breaker.
