Why do my emails keep reappearing on my android lg when I've deleted them

[Android Central Question]

How do I get them to delete permanently

You delete them on the phone, but they're still on the server. Go to the server and delete them. (If it's a gmail account, go to GMail.)

Which phone?
Which version of android?
Which carrier?
Which email app?
Which email provider?
Which email protocol (POP3, IMAP, Exchange)?

The modern protocols should be properly sync-ing the phone and server, including the deletes.
