Sending a message to a person who does not know you is always a bit nerve-wracking because you do not want to sound like a bother. It is hard to find that balance between being professional and being too friendly. You want to show that you can help their business grow without sounding like a robot or a pushy salesperson. I usually think that mentioning something specific about their work is a good start. How do you guys start these conversations to get a positive reply?
