I'm adding direct mail as a sourcing tool as I search for a company in the home services space. Has anyone had success getting someone to respond to a direct mail approach? I was going to do a hand written note on card stock, with a QR code printed on there to direct them to a website to tell more about myself, what I'm looking for, and about exiting your business (still building this). Does anyone have feedback what kind of messaging and/or format that has been helpful in direct mail sourcing?
