When you add a gmail account to an iOS device, the default “swipe left” action when discarding email is to archive the email, whereas for all other accounts (i.e. hotmail) the default action is delete.
If you want to change that, here’s how.
- Tap Settings
- Tap Mail, Contacts, Calendars
- Tap Gmail
- Tap Account
- Tap Advanced (at the bottom of the screen, you may have to scroll down)
- In the “MOVE DISCARDED MESSAGES INTO section, select either Deleted Mailbox or Archive Mailbox
- Press the Home button
