You’ll need to determine how to create an inbox rule for your mail system. Most mail clients let you set up filters or rules that can alert you about specific incoming emails that may be crucial. Instructions vary, so check the Help pages on the provider’s web site for details. However, this is the gist of what you want to do:

  • Check message when they arrive in the Inbox.
  • Look for messages from the boss, or the key client, or the support ticket system …
  • … with certain words in the Subject line, etc.
  • When found, trigger a special alert to get your attention.
