Ewing G. I had exactly the same situation with Klavyio and it turns out that it's actually a bit of a trend on Klavyio that the OR is very high, so I would focus more on the CTR and conversion from the email channel. Once you introduce apple privacy very many emails are opened for the customer, so you have a lot of false opens. The situation is similar with gmail. Here it might help in a way to exclude open's from Apple, or Gmail. I can send you on priv where there are metrics about specific deliverability providers and opens, but you won't get much out of it.
What you can do is for example
1. Please try to send the same campaign to different mails - gmail, yahoo, apple, verizon etc.
2. You could, for example, do a survey to your email base asking if the emails you send are of interest to customers. If 25% answer yes and the rest answer no then you have a lead. Quartz does something like this at the end of an email that asks the customer
about whether a particular email was interesting.
3. according to this article it has to do with bots, but they have already implemented a fix in the system and Klavyio is supposedly no longer measuring opens and clicks, but I haven't noticed an improvement in overly high ORs - https://community.klaviyo.com/analytics%2Dand%2Ddeliverability%2D72/spike%2Din%2Dopen%2Dclick%2Drates%2Dfor%2Dhotmail%2D11913
