This kind of message is great if you’re looking to validate an idea or find your first few customers. It works best when you offer something valuable upfront, like free early access or a sample. Make sure it feels personal by referencing a specific interest or brand they follow. Don’t send the exact same message to everyone, or Facebook might flag you as spam. And when you ask for feedback, be specific: “What do you think of the fit?” will get you better answers than “Thoughts?” Keep it short, human, and easy to respond to. That’s what gets results.
