Free Email Security Score & Domain Risk Rating — Frequently Asked Questions
What's included in a full email security score check?
A complete check evaluates SPF validity, DKIM signing, DMARC policy strength and alignment, and often BIMI readiness — combined into one overall grade.
Can I check if my domain is currently spoofable?
Yes — a low email security score (especially missing or "none" DMARC) is a direct indicator that your domain can be spoofed by attackers right now.
How is the score typically graded?
Most tools use a letter grade (A–F) or percentage score, weighting DMARC enforcement and SPF/DKIM alignment most heavily since these directly prevent spoofing.
Is an email security score check useful for small businesses without IT staff?
Yes, it's designed to translate technical DNS configurations into a clear, actionable score so non-technical teams know exactly what's missing.
Do email security scores affect whether my newsletters reach the inbox?
Yes — major providers factor authentication strength into inbox placement decisions, so a higher score correlates directly with better deliverability.
How often does my score change without me doing anything?
Rarely on its own, but expired DKIM keys, changed mail providers without updating SPF, or new Gmail/Yahoo policy requirements can silently lower your score over time.
What does an email security score measure?
It combines the status of your SPF, DKIM, DMARC, and BIMI records into one overall grade, showing at a glance how well-protected your domain is against spoofing and phishing.
What is considered a "good" email security score?
A strong score typically means SPF and DKIM both pass and align, DMARC is set to quarantine or reject (not "none"), and there are no DNS misconfigurations.
Why does my domain have a low email security score?
Low scores usually come from a missing or weak DMARC policy, no DKIM signing, an invalid SPF record, or having multiple conflicting DNS records.
How often should I check my email security score?
Check it after any change to your email provider or DNS, and at least quarterly, since misconfigurations and expired records can silently degrade your score over time.
Does a higher email security score improve deliverability?
Yes — mailbox providers like Gmail and Outlook increasingly weight authentication status when deciding whether your email lands in the inbox or spam folder.
Can agencies check email security scores for multiple client domains at once?
Yes, bulk or API-based scanning is common for agencies and MSPs managing email security across many client domains simultaneously.
Does an email security score check work for e-commerce platforms like Shopify with multiple sending sources?
Yes, the check evaluates your domain's overall SPF/DKIM/DMARC configuration regardless of how many platforms send on your behalf, as long as each is properly included and aligned.
How is an email security score different from a general domain security audit?
An email security score focuses specifically on email authentication (SPF, DKIM, DMARC, BIMI), while a broader domain security audit might also cover SSL, DNS security extensions, and web application vulnerabilities.
Is there a free all-in-one checker instead of testing SPF, DKIM, and DMARC separately?
Yes, an email security score tool is designed specifically to combine all these checks into a single free scan and report, saving time versus checking each individually.
Can I use an email security score to prove compliance to a client or auditor?
Many businesses use these reports as supporting documentation for security reviews or vendor assessments, though always confirm your auditor's specific requirements before relying solely on a third-party score.
How is this different from MXToolbox's overall domain health check?
Both cover similar ground, but a dedicated email security score tool often emphasizes an easy-to-understand single grade rather than a list of separate technical test results.
What is an email security score and who typically needs to check it?
It's a composite grade of your domain's SPF, DKIM, DMARC, and BIMI configuration — useful for any organization wanting a quick, non-technical way to assess spoofing risk and email trustworthiness.
Why should financial services firms prioritize checking their email security score?
Given how frequently financial brands are impersonated in phishing and wire fraud schemes, a strong, enforced score materially reduces the chance their domain is successfully spoofed.
Is an email security score check relevant for healthcare organizations beyond compliance?
Yes, beyond any compliance considerations, it's a practical safeguard against domain impersonation in phishing attempts targeting patients or staff.
Do real estate brokerages use email security scores to reassure clients during transactions?
Increasingly yes, since wire fraud tied to spoofed real estate emails has pushed brokerages to proactively verify and improve their authentication posture.
Should nonprofits with limited IT resources still check their email security score?
Yes — it's specifically useful for organizations without dedicated IT staff, since it translates technical DNS configuration into a simple, actionable score.
Can law firms use an email security score as part of client-facing security assurances?
Yes, some firms reference their email authentication posture when discussing data handling practices with security-conscious clients, particularly in industries like legal, finance, and healthcare.
What is an Email Security Score and how is it calculated?
IncogSay's Email Security Score evaluates your domain's complete anti-spoofing and deliverability posture across five critical pillars: SPF protocol compliance, DKIM cryptographic signature strength, DMARC policy enforcement (p=reject / p=quarantine), BIMI brand trust certification, and MX mail exchange redundancy.
What is a good email security rating?
A score of 85–100 indicates robust protection against spoofing, phishing, and impersonation. A score below 60 signals critical vulnerabilities (such as missing DMARC or SPF '+all' misconfigurations) that allow bad actors to impersonate your domain.
How to check email security rating for any domain?
Enter the domain name into our Email Security Score auditor. The tool queries DNS over HTTPS in real-time, audits all records against RFC security standards, and computes an instant grade.
Why is email authentication essential for Gmail and Yahoo deliverability?
In 2024, Google and Yahoo introduced strict requirements for email senders: SPF and DKIM must be configured, DMARC must be published, spam rates must stay below 0.3%, and reverse DNS (PTR) must be valid. Failing these requirements causes emails to land in spam or be rejected.
How to improve my domain's email risk score?
1. Enforce DMARC at 'p=reject'; 2. Maintain SPF lookups under 10 with '~all' or '-all'; 3. Sign all outbound mail with 2048-bit DKIM keys; 4. Publish BIMI records with an official logo SVG.
Is IncogSay's email security score check free?
Yes. IncogSay provides a 100% free email risk score, email domain security check, and mail security rating tool with zero registration.
