How to Choose the Right Alternative

Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
In emails, pair a formal opening alternative with a warm closing one to sound polished but human.
Avoid sarcastic or funny alternatives in serious conversations. Tone misfires are hard to unsend.
For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
Save two or three favorites instead of memorizing the whole list. Rotating a few keeps your wording fresh.
