An efficient and simple way to rationalize your workflow is to create Predefined answers for support queries that can be answered with a single, general response.
This saves you time and struggle of formulating a separate reply to each customer that has the same issue.
ExampleSubject: Recurring order for LiveAgent failed
Message: We have been informed that your recurring order for LiveAgent failed. The credit card was declined, so please try another card [update the billing information inside LiveAgent agent panel in the "My Accounts" section] or make sure you have enough funds on the actual card. Also make sure your bank is not declining the automated order.
To trigger a Predefined answer simply hit CTRL+I while typing or click the Predefined answer icon and select from your saved Predefined answer.
