Add daily monitoring
Your report is linked to . Pro adds scheduled daily checks and email updates when issues are detected.
What we check
One domain.
Seven checks.
Read public DNS records and probe accessible mail servers. Each finding includes its status and a suggested next step where available.
A configuration check does not test inbox placement or verify a sent message.
- MX01
- Where incoming mail is routed.
- SPF02
- The published sender policy and nested DNS lookups.
- DKIM03
- Keys at common selectors. Custom selectors can be missed.
- DMARC04
- The policy for failed authentication and reporting settings.
- TLS / STARTTLS05
- Encrypted connections on the selected mail server.
- Reverse DNS06
- The hostname associated with the mail-server IP.
- IP blocklists07
- Listings for observed mail-server IPs, which may differ from outbound IPs.

Before you start
A few useful details.
Will this change my DNS?
No. The audit reads public records and probes accessible mail servers. You or your provider makes any changes after reviewing the findings.
Does a good score guarantee inbox delivery?
No. The score summarizes configuration checks. Reputation, recipient feedback, message content, and provider decisions also affect delivery. Inboxproof does not send placement-test messages.
Can this verify a message’s DKIM signature?
The domain check searches common selectors for published keys. To inspect the signature and alignment on an actual message, use our email header analyzer.
What happens if I add my email?
Email is optional. Add it to save a report to your account. Paid monitoring sends updates from scheduled checks. See the privacy page for data handling.
How is the score calculated?
Each check has a fixed weight. A pass earns its full weight, a warning earns half, and a failure earns zero. Review the individual findings alongside the total.
