I need to delete 4000 emails from my ipad

Contact Apple support on this question.

If you have set up your email account as an IMAP account, your emails are on the server, but if you delete them on your iPad, they are also delete on the server.
if you have set up your email account as a POP3 account, your emails are downloaded to your iPad ... if you delete them on your iPad, they are still on the server, so you can retrieve them. However, POP3 accounts don't show you the email folders that are on the server. You need to decide which is more important to you. On the iPad, do you want privacy (POP3) or flexibility (IMAP).
A POP3 account will also continue to use up more space (memory) and not clean-up (clear) ... eventually, you will have to delete the account to try to minimize the amount of used space. I don't know why it does this, but I have been fighting this problem for 4 years on two different versions of the iPhone. My iPhone is setup as POP3, while my iPad is set up as IMAP. I have not found a good answer to this problem.
