Email Security Score Guide: Run, Read and Act on the Results
MXFend's Email Security Score groups observable domain checks into a single report so you can find configuration gaps and open the detailed evidence behind them. The score is a prioritization aid, not a promise that a mailbox provider will place every message in the inbox.
Enter a domain, run the scan, then start with failed checks and warnings rather than the numeric score alone. Review MX routing, SPF, DKIM, DMARC, transport security and reputation evidence, open the relevant checker or guide, make one controlled change at a time, and rescan after DNS propagation.
Overview
The free scan observes public DNS and network evidence available to the checker. It cannot see private provider dashboards, every outbound message, recipient engagement, complaint data or all account-level policies. A high score therefore means the tested technical surface looks healthier; it does not guarantee delivery or inbox placement.
The paid DNS Fix Report is conditional. MXFend offers it only when the scan finds an actual issue that can benefit from a prioritized implementation plan. A clean result must not create or display a report purchase path.
Why it happens
Email configuration is distributed across DNS, sending platforms and receiving infrastructure. A grouped scan reduces the chance of fixing one symptom while missing another dependency, but each result still needs context. For example, a published SPF record can be syntactically valid while omitting a real sender, and a valid DMARC record can still receive no aligned mail.
How to fix it
Open the highest-priority failed item, read its evidence, and verify it with the dedicated tool. Confirm the intended provider configuration before editing DNS. After publishing a change, wait for the relevant TTL and caches, rerun the focused checker, then rerun the score. Preserve message headers and SMTP responses for problems that public DNS alone cannot explain.
Common mistakes
Do not optimize only for the score number, change several records at once, treat an informational lookup error as proof of a listing, assume every DKIM selector can be discovered automatically, or buy a remediation report when the scan found no actionable problem.
Checklist
- Scan the organizational domain used in visible From addresses.
- Start with failed checks, then warnings, then informational findings.
- Open the evidence and matching dedicated checker before editing DNS.
- Confirm all real sending platforms, selectors and receiving providers.
- Make controlled changes and respect DNS TTL before retesting.
- Verify real-message SPF, DKIM and DMARC alignment from message headers.
- Treat the score as technical guidance, not an inbox-placement guarantee.
- Use the DNS Fix Report only when the scan exposes an actionable issue and offers it.
How to run the scan
Use the domain after the @ in the organization's normal From address. The scan does not need a mailbox password. For organizations using multiple branded domains, scan each domain that sends or receives independently.
How to read result groups
MX and DNS findings describe routing and published records. SPF, DKIM and DMARC findings describe authorization, signatures, policy and alignment readiness. Transport findings cover observable TLS controls. Reputation checks report the public responses the scanner can safely interpret. Passed checks confirm the tested condition, not every message.
What to do after the scan
Use related tools to isolate a finding, consult the relevant provider instructions, and validate a real message where authentication alignment matters. If an actionable DNS problem exists, the scan can offer a DNS Fix Report; if the result is clean, the paid report path stays unavailable.

Does a high Email Security Score guarantee inbox placement?
No. It reflects the technical checks MXFend can observe. Mailbox providers also use reputation, recipient feedback, content and private policies.
Why can a check pass while real mail still fails authentication?
A DNS check can confirm that a record exists and is structurally valid. A real message can use another envelope domain, selector, sending IP or platform, so inspect message headers as well.
When is the paid DNS Fix Report offered?
Only when the scan finds a genuine actionable problem that the report can help implement. A clean scan does not offer or create the paid report.
