Hi community,
I experienced extremely high bounce rate for one of my marketing campaigns with 12% bounce rate coming from Soft Bounce and error 554.5.7.1 CS01 message rejected due to local policy.
This damages my account reputation and I don’t find any plausible explanation to why this happened and how to fix this.
In deliverability report I can see that all errors come from Apple domains and from the Content category.

This is the first time. All previous campaigns were delivered absolutely fine with bounce rate below 2%.
Did anyone else experience this? What would you advice to do next?
Thank you!
