How to Choose the Right Alternative

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.
Avoid sarcastic or funny alternatives in serious conversations. Tone misfires are hard to unsend.
Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
