How BizMailNet approaches a diagnosis
1
Describe the issue
Tell us what's happening, without needing to know the jargon.
2
Inspect the evidence
Run focused checks, then see what was observed versus merely reported.
3
Understand the next step
Get actionable guidance and clear limits on what can be determined.
Designed for trust
Passing SPF, DKIM and DMARC does not guarantee inbox delivery.
Spam placement can depend on filtering rules, sender history, content, recipient behavior and information only the email provider can see. We will never represent a DNS-only check as proof that an email reached an inbox.
