why won't my emails delete

[AC Question]

I have tried over and over to delete my emails and they keep coming back why

Welcome to Android Central! Which phone, email app, and email provider are you using? If you're using a POP3 server, check the account settings in the Email app for an option to delete emails on the server or not.

As was asked, I think the first question is what email client are you using?
