Most emails should hit 45% open rates. If yours don't, A/B test your subject line, preview text, and send time one at a time. If that doesn't work, you probably have a deliverability problem.
In terms of the open rate, kind of the benchmark with a lot of this should be right around 45% or, or kind of north of 45%. And if you're not there, I would start by trying things like the subject line, the preview text, and send times. So A/B testing those, obviously one variable at a time. If you're still having issues with those and no matter how much testing and no matter how much segmentation you're leveraging and whatnot, you just can't get above it, there's probably a likelihood that you have some sort of deliverability issue that needs to be addressed.
