Email filters don't work, no spam training

Hi there. We understand the nuisance spam emails can cause. Most of us that use email can all relate! There are several things that we are doing and that we have in place for these types of situations. I wanted to provide some links to you that I think will provide a lot of additional insight.

Good afternoon,

Reviewing your email logs, the "ali glag" emails - they appear to be coming from google groups. Indicating that you are subscribed to a google group and for that reason is not marked as spam. Similarly for the "marwa hasaan" emails. Due to being emails from google groups and needing to be added to the group or manually sign up yourself the emails are categorized as social emails and are not commonly flagged for spam. When you get a chance can you review the email headers for one of those emails and see if there is an unsubscribe link within the headers? or any indication to which google groups you are a part of(likely not intentionally from the sounds of it)?

To also note, our spam filter processes over a billion spam messages daily, just happens that in this instance the types of emails you consider spam are ones you have to either sign up for or be asked to signed up for via google groups. Also, the marking of emails as spam takes the reports into account on a entire platform wide level and not individual level. The spam filter is a wholistic filtration system for all comcast.net users and are not tailored per user. The users however can influence the filtration system if enough reports are received. For example, if 10,000 people get the same spam emails and all 10,000 mark the emails as spam, the filter will acknowledge and mark future emails as spam. If 1 person gets a spam email and they mark it as spam, there isn't enough data or reason to immediately mark the email as spam. In your example checking our overall server logs there are users who have even added this sender to their address book indicating that there is an amount of these emails that some users would like to receive on our platform to their inbox intentionally. Like the saying goes "one mans trash is another mans treasure". Overall, like I mentioned earlier its a google groups email and with a little digging into what email group you are signed up for with google groups, you can unsubscribe from the email group as per https://support.google.com/groups/answer/46608?hl=en 

Glad it worked for this person. But I've been trying to use Xfinity email filters for the past year for junk I never signed up for and the filters do nothing. The article they always refer you to does not explain in detail how the filtering mechanism works. For example, there is a down arrow next to each filter I create. Am I supposed to click on this? If I do it changes to a circle with a line though it. What does all this mean? How about providing some actual filter setups in the article.
