Someone on HN sent me a cold email recently asking me to help beta test their web app. They'd found me via a comment where I'd mentioned using a competitor's app, and wanted my opinion / feedback on their own app. What they did right is that the first email wasn't a sales pitch, just asking for feedback / opinions / bug reports. What didn't go well is that they seemed rather defensive about my negative feedback. If you do get negative feedback, remember it might be specific to that person's situation - the same app might be perfect for someone else, and you can use the feedback to identify who is & isn't your target market.
