How to Choose the Right Alternative

Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
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.
Do not stack two formal phrases back to back. One polished line plus plain language reads better.
Read the alternative out loud before sending. If it sounds like something you would actually say, it is ready.
