Know your deliverability score before you send
9-check analysis: SPF, DKIM, DMARC, PTR, DNSBL, BIMI, ARC, TLS
The reputation service runs 9 deliverability checks against any domain: SPF alignment, DKIM configuration, DMARC policy, reverse DNS (PTR), 20+ DNSBL blacklist lookups, BIMI presence, ARC chain validation, TLS support, and a composite 0-100 deliverability report.
The Deliverability Blind Spot
Comprehensive Reputation Analysis
Nine independent checks cover every factor that affects email deliverability. Composite score tells you if it's safe to send.
SPF/DKIM/DMARC
Verify sender authentication is correctly configured. Check SPF includes, DKIM selector, and DMARC policy (none/quarantine/reject).
PTR/Reverse DNS
Verify sending IP has a valid PTR record. Missing reverse DNS is a major spam signal.
20+ DNSBL Checks
Check sending IP against 20+ DNS-based blacklists simultaneously. Identify which lists have flagged your IP.
Composite Score
0-100 deliverability score combining all 9 checks. Scores below 60 trigger auto-block on outbound campaigns.
BIMI/ARC/TLS
Check for BIMI (brand indicators), ARC chain (forwarding authentication), and TLS support.
Domain Trust Score
Holistic trust assessment: domain age, authentication records, blacklist status, sending history.
Deliverability Analysis Pipeline
Each stage processes data sequentially with full checkpoint/resume capability.
SPF Check
Parse SPF TXT record. Verify authorized senders. Check for too many DNS lookups (>10).
DKIM Check
Query DKIM selector records. Verify key length and algorithm.
DMARC Check
Parse DMARC policy. Check alignment mode (strict/relaxed). Verify reporting addresses.
PTR Check
Reverse DNS lookup on sending IP. Verify PTR record matches forward DNS.
DNSBL Check
Query 20+ blacklists in parallel. Report which lists have flagged the IP.
BIMI Check
Check for Brand Indicators for Message Identification. Validates VMC certificate.
ARC Check
Verify Authenticated Received Chain for forwarded message handling.
TLS Check
Verify MX servers support TLS. Check for STARTTLS and TLS version.
Composite Report
Weight all checks into 0-100 score. Generate actionable recommendations.
