Auto-intro messages before calling unknown contacts

Simple WhatsApp etiquette: If you’re contacting someone you don’t know, text first and introduce yourself. Don’t just go straight to calling someone who doesn’t have your number saved. If you must call before texting, after the “hello,” properly introduce yourself and explain how you got the contact. Because how will you just say, “Hi, I want to do work” do I know if you’re trying to hire an assassin or if you’re the assassin yourself? 😅
