how to remove tags?

I understand that the tag works like the folder but how can you delete a tag (folder)? and also… how can you untag a mail?

Hi,

Thanks for writing in. To untag a mail, just click on the list of tags and the tag picker you used to tag the email to begin with will appear. Click on the tag you want to remove and it will be un-highlighted.

Mailroom only shows tags that are actually used. To delete a tag, all you need to do is to untag the conversations.
