Do you often send the same message to the potential tenants? Then you can without difficulty save your answer and use it as a "standard message". For example if you have a certain procedure for follow-up or often reject candidates who do not meet your criterias.
You save the message as a standard message right before sending it and then you can easily find it next time you need it. Remember to give the standard message a descriptive name so that you have an overview over your saved standard messages.
