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.
For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
In emails, pair a formal opening alternative with a warm closing one to sound polished but human.
Do not stack two formal phrases back to back. One polished line plus plain language reads better.
Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
