What happened to the select all/delete email option on the S6?

[AC Question]

I upgraded from a galaxy S4 to an S6. On my S4 I could delete all of the emails in my inbox at one time by selecting the select all option in my menu and then selecting delete. I cannot find a way to do this on the S6. I get a lot of emails daily, many of which I don't want to read. I don't like have to delete each email individually one at a time.
