How to Choose the Right Alternative

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.
Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
Do not stack two formal phrases back to back. One polished line plus plain language reads better.
