How to block unwanted e-mails

If you receive an e-mail that is junk/SPAM there are a couple of ways to stop them from going into your in-box.
The first way, highlight the offending message, and click on the … on the upper right side of the screen then click mark as junk. This will then send any messages from that address to your junk folder. 

The next way is to click on the cog in the upper right corner of the screen and click on Options.

Once the Options page opens click on block or allow, under the blocked senders heading you can then add the address or domain that you want to block, then click the + and save.  SPAMMERS change their address often so it is more effective to enter the domain, which is the @ and whatever follows it such as @onecallnow.com
