In Marketing Cloud, we are seeing emails sent to a particular domain receive a lot of Hard and Block bounces, but the same emails that are being blocked are still being opened and clicked on randomly (there is no pattern). So this is a general question if anyone out there also sees similar behaviour?
It is possible to encounter a situation where a lot (over 100) people who regularly throw Hard/Block bounce messages but actually still open/click emails? It is making bounce management very awkward.
Examples of these bounces are (with email addresses blanked out): 5.0.0 (undefined status) permanent failure for one or more recipients (firstname.lastname@example.org:blocked) 5.1.1 Generating server: email@example.com__#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found
