Eric Siu explains how to write cold emails people actually open. Use a neutral subject line like "hi from Alex" or "quick question" instead of pitching. Think like the recipient, not the sender.

The first thing I like to do is think about cold emails as the recipient. All of us have received cold emails in the past, and it's pretty obvious when you receive a bad cold email why it's bad. A couple things hit you right away. One, when you look into your Gmail inbox, you'll see the subject line. Two, you'll see a little bit of the first line of the email, and those 2 things will make you decide whether to delete that email or whether to open it. So the first thing to do is to make sure the subject line is at least neutral. That's why I like generic subject lines. I'm a big fan of, hi from Alex. I'm a big fan of, quick question. The one that performs the best for us at Experiment 27. The reason why those generic subject lines work is because they don't turn somebody off. If you had pitched your product in that subject line, there's a much higher chance you're gonna get deleted, which means they're not even gonna read the body of the email.
