Report spam that makes it to your Gmail inbox so you will see less of similar junk in the future.

The Good Thing Is: Reporting Spam Makes for a Better Gmail Spam Filter

The more spam Gmail sees, the less spam you get in your inbox; this, at least, is the idea.

You can help Gmail's spam filter learn—by showing it the junk that made it to your inbox, of course.

Reporting spam is easy and will not only rid you of similar junk in the future but purge the immediately offending message—immediately.

Blocking Is Also an Option—for Individual Senders

For messages from specific, obnoxious senders, blocking is usually the better option than reporting these messages as spam. Chances are, these messages will not look like typical spam, and so they may confuse the spam filter more than they can help.

Use blocking only for individual senders—people who continue to forward you messages, for instance—, though, and not for spam. Junk mail senders will not usually have identifiable and persistent senders. Typically, the address will be random, and blocking does nothing to stop the inflow of spam.
