how do i clear emails from iPad in bulk

In the mail app, over on the left, you will see all mailboxes you have linked to your app. On the lower part of that you will see each account, tap on that and it should being up just that inbox or whatever folder you want. Tap on edit then select all and you can delete them as a group instead of one at a time

Another way could be to access your mail via the web interface, for example if you use yahoo. go to yahoo.com (ignore hwen it wants you to install the app) and sign in. You can then also bulk delete.

This works on iPhone... I personally haven't tried it on an iPad but it should work.

This will delete everything from the mail box without having to select every email individually.

Go the mailbox that you want to delete all messages from.

In the upper right hand corner, select 'Edit'.

Tap on one of the circles to put a blue check mark next to one message. You only need to select one.

Now touch and hold the 'Move' button at the bottom of the screen. Hold it, do not release.

While still holding 'move', uncheck the message you checked in the step above.

Now release 'Hold'.

On the following screen select 'Trash'.

All messages will be moved to the trash.
