Domain Reputation Checker
A composite score covering SPF, DMARC, MX configuration, and threat intelligence — with concrete fixes for anything that's missing.
About the Domain Reputation
Your domain's email reputation is the sum of many signals: proper authentication, correct mail configuration, and a clean safety record. This tool runs those checks together and produces a single score with concrete, prioritized fixes for anything that's dragging it down.
What this tool checks
It evaluates your SPF and DMARC records, confirms MX records are configured, and checks the domain against Google Safe Browsing. Each factor adjusts the score, and every failure comes with a specific suggestion.
How the score works
The score starts at 100 and drops for each missing or misconfigured element, weighted by impact — missing DMARC costs more than a missing AAAA record. The result is a snapshot of email trustworthiness with a clear path to improvement.
Frequently asked questions
What affects domain email reputation?
The biggest factors are proper SPF, DKIM, and DMARC setup, correct MX configuration, a clean sending history, and not appearing on blocklists or threat databases. Consistent, authenticated sending builds reputation over time.
How can I improve my domain's reputation?
Publish valid SPF, DKIM, and DMARC records, keep your mail configuration correct, avoid sending to invalid addresses, and monitor blocklists. Fix any issues this tool flags, starting with authentication.
Does domain age affect reputation?
Established domains with a consistent sending history are generally trusted more than brand-new ones. New domains should warm up gradually and get authentication right from day one to build reputation.
