Take a little time to consider the order of your filters. Filter 1 is the first filter applied to an incoming message, Filter 2 is next, and so on, until a match is made or all filters are passed. If no filters match an incoming message, it is delivered to your Inbox.
This example shows why the order of your filters matters:
Let's say your sister has an email account with "NeatMail." If your first filter is an "@neatmail" filter (any address that contains "@neatmail"), and your second filter is a Family filter (any address that contains your last name), then the @neatmail filter will send her messages into the folder you specified for the @neatmail filter—instead of into the folder you specified for the Family filter, every time. Because the @neatmail filter comes first. And that could be frustrating when you go looking for her messages in your Family folder!
To change the order of your filters, click a filter name to highlight it, then click the Up or Down buttons to the right to push the filter up the list or to drop it down.
To edit or delete a filter, click its name to highlight it, then click either the "Edit" button or the "Delete" button.
