How to Choose the Right Alternative

  1. Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
  2. Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
  3. Save two or three favorites instead of memorizing the whole list. Rotating a few keeps your wording fresh.
  4. Read the alternative out loud before sending. If it sounds like something you would actually say, it is ready.
  5. In emails, pair a formal opening alternative with a warm closing one to sound polished but human.
