Filter power

Gmail's filters allow you to manage the flow of incoming messages. Using filters, you can automatically label, archive, delete, star, or forward your mail, based on any combination of keywords, sender, recipients, and more.

But there are some hidden things which we don't know.We can make use of "Or"and "and".This is of great use like when subscribing for newsletter.


So make a filter called "newsletters" and when you receive newsletters that are not in the filter, simply add them to that filter.
What I have done is created one where the "skip inbox" is checked off and the "From" field looks like this "newsletter@whatever.com OR newsletters@skipit.com OR ..." and I add an "OR new@newsletter.com" when one in not in the filter.


Similarly "AND" can also be used.

This is quiet useful as Google allows only 15 filters.
