Remember when you use the rule ‘OR’ that for example: if you insert ‘yes’ OR ‘no’ in the the title the system will filter all emails, which contain the words ‘yes’ or ‘no’ in their title.
If however you choose to use ‘AND’ using the same example: if you insert ‘yes’ AND ‘no’ in the title the system will filter all emails which contain both ‘yes’ and ‘no’.
IMPORTANT: OR/AND should be entered in CAPITALS.
