I would say open rate is one of those things that I definitely still respect and kind of see where things fluctuate with it. You can definitely definitely tell the difference between a quality newsletter and a not so color newsletter just based on the open rates that they're seeing. It'd be one of those for me on the paid acquisitions side of things because again, you can really tell just on like the surface level of engagement with the open rate whether you're acquiring in great engaged readers or not. If your ads are just like almost too sexy and acquiring just anyone and everyone and it's not really paying dividends in terms of like engagement for your newsletter. And again, you know, click rates.
