In emails, pair a formal opening alternative with a warm closing one to sound polished but human.
Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
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.
