This server accepts all emails, but may still bounce later or quietly drop messages. Proceed with caution.
High risk of instant bounce or zero engagement. Recommend removal from active sequences.
A pass does not always mean safe to send, and a warning does not always mean remove it. We'll give you enough context to make the call.
