Love that! I guess it's a billion dollar question. I can share my approach: My startup is targeting early founders. We're building an app to help you stay in touch with users through a Segment.com integration. So here's how I cold email: I get emails from founders on Indiehacker that have some revenue, are web based and make revenue through subscription. https://www.indiehackers.com/products https://www.indiehackers.com/products lets you target really well. Then, I use Clearbit to figure out if they're using Segment. And if they are, I shoot them an email to briefly explain what we do and that they can give us a try and get set up in a few seconds because they are already using Segment. It's the same email for everyone but already pretty personal due to the initial research. Would love your thoughts on this!
