15 tools Lookup & Checker Tools
Once authentication records are published in DNS, the next step is confirming they actually work. Lookup and checker tools pull DNS records directly from authoritative servers and analyze how those records are configured — surfacing problems before they affect deliverability.
Authentication Protocol Checkers
DMARC Record Checker
Retrieve your domain's DMARC policy from DNS and examine how it's configured. Validates policy, alignment settings, reporting destinations, and syntax.
- DMARC record retrieval and policy validation

SPF Record Lookup
Retrieve and analyze your SPF record. Inspect mechanisms, validate syntax, verify authorized senders, and evaluate lookup chain limits.
- SPF TXT record retrieval and mechanism inspection
- Syntax validation and authorization analysis
- Lookup chain evaluation for potential failures
DKIM Record Lookup
Retrieve the public key associated with a selector and verify that the record exists, resolves correctly, and is structured properly.
- Selector-based record retrieval

- PTR record retrieval and forward resolution validation
- FCrDNS verification for IP-to-hostname mapping
DNS Record Checkers
Authentication failures often trace back to DNS. A missing nameserver. An MX record pointing somewhere unexpected. TXT records that never propagated. PowerDMARC's DNS record checkers retrieve these records directly from DNS so administrators can quickly see how a domain's infrastructure is actually configured.
NS Record Checker
Retrieve nameserver records. Verify DNS delegation and identify authoritative servers.
Check →MX Record Checker
Retrieve mail exchange records. Identify inbound mail servers and verify priority configuration.
Check →Whois Checker
Retrieve domain registration details including registrar, dates, and ownership metadata.
Check →Blocklist Checker
Scan multiple reputation sources to determine if a domain or IP appears on known blocklists.
Check →PTR Checker
Retrieve reverse DNS records. Verify IP-to-hostname mapping and correct reverse DNS configuration.
Check →A Record Checker
Retrieve IPv4 address mappings. Confirm DNS resolution and identify configuration inconsistencies.
Check →AAAA Record Checker

Your Complete Email Authentication Journey
Email authentication rarely happens all at once. Most teams move through it in stages — from initial configuration to ongoing monitoring and enforcement. PowerDMARC's tools support each step of that process.
Setup
Create correctly formatted SPF, DKIM, DMARC, BIMI, and TLS records using generator tools.
Verification
Use lookup and checker tools to confirm records resolve correctly and policies are visible.
Monitoring
Track authentication activity, message behaviour, and reputation signals.
Enforcement
Strengthen DMARC policies, manage compliance, and protect domains from spoofing.
Compliance & Monitoring — Premium Solutions
Generators and lookup tools help configure authentication. Keeping those policies working over time is a different problem. Without monitoring, issues surface late — usually when deliverability drops or abuse reports start appearing. PowerDMARC's premium solutions focus on monitoring, automation, and compliance management as email infrastructure evolves.

Frequently Asked Questions
Are PowerDMARC's tools really free?
Yes. All generator, lookup, checker, and advanced tools are free to use with no signup required. Premium solutions for monitoring, managed deployment, and compliance reporting are available as paid plans.
What's the difference between a generator and a lookup tool?
Generator tools create new DNS records ready to publish. Lookup and checker tools retrieve existing records from DNS to verify they're correctly configured and actively resolving.
Which tool should I start with?
If you haven't set up email authentication yet, start with the generator tools to create SPF, DKIM, and DMARC records. If records are already published, use the checker tools to verify they're working correctly.
What does the DMARC Report Analyzer do?
It processes the raw XML aggregate reports sent by receiving mail servers and presents the data in a readable format — showing which sources are sending mail on your behalf, authentication pass/fail rates, and any unauthorized senders.
Do I need all six authentication protocols?
SPF, DKIM, and DMARC are the core protocols and should be implemented together. BIMI requires DMARC enforcement first. MTA-STS and TLS-RPT add encryption enforcement and reporting. Each layer provides additional protection and visibility.
What are the premium solutions for?
Premium solutions handle ongoing monitoring, policy management, and compliance. They're designed for organizations that need real-time reporting, managed deployment across complex environments, regulatory compliance evidence, or multi-tenant management for MSPs.
Can MSPs use PowerDMARC to manage multiple clients?
Yes. The Multi-Tenant Management solution provides centralized visibility across all client domains, white-label management options, and the operational scalability needed to manage authentication environments at scale.
Which compliance frameworks does PowerDMARC support?
PowerDMARC's Compliance Reporting solution generates documentation aligned with HIPAA, SOC 2, PCI-DSS, and GDPR frameworks, including authentication policy records and audit trail support.
