My cousin did a similar test but with dog toys. She got ads for them after three days, but she also follows a bunch of pet accounts on Instagram. It's all that connected data, like who you talk to online.

My routine is just checking for snacks in the fridge lol

My uncle taught me basic blacksmithing when I was fifteen. He could forge a simple camp knife in about an hour, including heat treating. That ten minute claim does sound like an exaggeration for a finished blade, but maybe they meant just roughing out the shape? What kind of knife are we talking about here?

My old farrier taught me that trick years ago, and it really does hold better.

Wait, is that 12% reply rate to the initial cold email, or does it include people who just replied to say "stop emailing me"? I've seen people count any reply, even negative ones, and call it a win. A "get lost" isn't really moving the needle. If it's 12% actual interest, that's amazing. But if it's just more people telling you to go away, the video might just be making you more annoying, not more effective.
