How to delete Gmail Inbox on iPad

[vjaaan]

Mail is depleting my storage space on iPad Air. I would like to fully delete my Gmail Inbox to clear space and then let it repopulate with new mail.

I am trying one by one but it is not showing any gain in hard drive space on my iPad.

Any suggestions? Thanks.

Don't you need to do this on the gmail website? The mail app is only showing you what's in your mailbox, and you also need to check that it's not all just sitting in the archive folder.
