How to Choose the Right Alternative

  1. Read the alternative out loud before sending. If it sounds like something you would actually say, it is ready.
  2. Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
  3. Save two or three favorites instead of memorizing the whole list. Rotating a few keeps your wording fresh.
  4. In emails, pair a formal opening alternative with a warm closing one to sound polished but human.
  5. Do not stack two formal phrases back to back. One polished line plus plain language reads better.
