In your inbox, on the left hand side, you will see a listing of all
of the messages that have come in through your inbox. In each
listing, there is a little trash can on the right hand side. Simply
click on that trash can to get rid of any messages that you no
longer need in order to keep your inbox organized.
Hit the trash can by mistake? Don't worry this feature archives the texts so you can still access them if you need to.
