Many of our customers use message tags as an alternative to folders in order to organize and categorize their email.
You can now manage your message tags by clicking Tags in the left pane in Webmail, or by going directly to https://runbox.com/mail/tags. The Tag management screen lets you add and delete tags, and get an overview of the messages that are already tagged.
To add a tag to a message, just open the message, select the tag name (or [New tag] to enter a new tag name) and click “Add tag”.
