A MAC mail question.

If I double click on an email in my inbox, it nicely opens in a new window that I can place to the right of my inbox window.

I then delete it.

How do I get the next email in the inbox to open automatically in the new window?

I answer many hundreds of emails a day so can’t afford the time to go back into my inbox, find the next email, and double click on it to open it in a new window. I want it to automatically open in a new window (not just another pane under the inbox)

I’ve been all through preferences and don’t see how to do it.

You bought a MAC?

I don’t use Mac mail (I use web based mail only). But I looked it up online and couldn’t find a solution. I’ll play around with my Mac at work tomorrow and see if I can find a solution.

A MAC???

Oh…that’s an easy fix.
