I wish I could help, but I use yahoo, and don’t know how to control the settings in gmail. But in yahoo, there’s an “options” tab in the corner of the screen that let’s you change settings for spam, filter, general settings, etc. Maybe gmail has something like that?
At least I’m not the only one…I just have one site that sends me all these things so I created a filter to send it to spam (didn’t really work) and then every time I got one in my inbox I clicked mark as spam and deleted. Now I don’t get anything.
