Maybe, try setting-up a second Gmail account, then send transfer) your emails from the old username account to the new username account. If this works, then either try deleting the messages from the old gmail account and transfer the messages from the new gmail account back to the original gmail account ... or ... just delete the old gmail account if you successfully transferred them to the new gmail account.

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.
Whenever I download an ap, it appears on both my phone and the iPad. It's part of Apple's program of inter connectivity between all their products. I just take it off my phone if I don't want it there. It doesn't remove it from my iPad also when I do that.
Are you using the Mail app that comes with iOS ,
or are you using a different email program that you are trying access via a web browser ... Safari, Firefox, Google Chrome,... ?
if not using Apple's Mail app, the only way you can get access to email is to go to your Internet Service Provider's (ISP's) web site and login to your email program (e.g., Gmail) from there, or use an app for your specific email program ... e.g., the Gmail app.
Open Safari on your iPad and go to .
