How to Choose the Right Alternative

  1. For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
  2. Read the alternative out loud before sending. If it sounds like something you would actually say, it is ready.
  3. Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
  4. Avoid sarcastic or funny alternatives in serious conversations. Tone misfires are hard to unsend.
  5. In emails, pair a formal opening alternative with a warm closing one to sound polished but human.
