Why did FBL spam rate and identifier counts drop to zero affecting inbox placement?

Email marketer from StackOverflow user MailGuru answers that a zero-spam report might indicate a problem with FBL reporting itself, or an indication that emails aren't even making it to the inbox to be marked as spam. It's crucial to check raw bounces, and ensure mail servers are properly configured.

Email marketer from SendGrid shares that inbox placement issues often arise from poor list hygiene and authentication issues. If your spam rate is inexplicably low, it might be that your mail is going straight to the spam folder without being registered as spam complaints. Improving authentication (SPF, DKIM, DMARC) and cleaning your list are recommended.
