Rules are processed in the order they are listed in the Rules Wizard and you can rearrange the rules to better control which rules process which messages.

Add a Stop Processing action to each rule to prevent subsequent rules from processing messages which are processed by a rule. If you want more than one rule to process messages, don't add the stop processing action to earlier rules or put that rule at the top of your Rules list.

If you have a lot of rules, you'll improve the efficiency of Rules Wizard if you put the most active rules at the top of the list and use the Stop Processing action in most of your rules.
