    Comprehensive feature set — built to fix email deliverability

    From developers integrating an email verification API to email ops teams running inbox placement tests, MailQA covers every step of email QA: validation, rendering, authentication, spam scoring, and deliverability monitoring.

    Verification & Validation

    Syntax & RFC checks, MX record lookup, SMTP mailbox probe, catch-all detection, disposable domain database, and role address detection (admin@, support@). Use verification to remove invalid addresses and protect your sender reputation.

    • Real-time API & bulk CSV cleaning
    • Risk scores: low / medium / high
    • Pre-send hooks to block risky addresses

    Spam Score & Deliverability

    50+ spam filter checks (SpamAssassin-like scoring), blacklist & DNSBL scanning, header analysis, and spam trigger detection. We provide an inbox placement prediction and actionable remediation steps to reduce spam placement.

    • Spam trigger word highlights
    • Blacklist alerts
    • Recommendations to fix content, headers, and links

    Device Previews & Rendering

    Pixel-perfect previews across major email clients and devices (Gmail, Outlook, Apple Mail, Android), including dark mode simulation and mobile responsiveness checks. Identify rendering issues before every send.

    • Side-by-side comparisons
    • Image and CSS load diagnostics
    • Broken link / asset checker

    Authentication & Domain Health

    SPF, DKIM, DMARC checks and BIMI readiness reports. MailQA analyzes your DNS setup and gives an action list: fix SPF records, enable DKIM signing, and publish DMARC policies to protect domain reputation.

    • Suggested DNS records
    • DKIM key rotation reminders
    • DMARC aggregate reports

    API, Webhooks & Automations

    Robust REST API for real-time checks, webhooks for asynchronous flows, and SDKs for Node and Python. Integrate with Zapier, CRMs, and marketing platforms to keep lists clean automatically.

    • Webhook retries & queuing
    • CSV bulk API with progress

    Analytics & Suppression Management

    Track bounces, complaints, and sending reputation over time. Use suppression lists to automatically block hard bounces and unsubscribes to protect deliverability.

    • Exportable reports (CSV/PDF)
    • Team accounts & roles
    • Custom retention & storage policies

    How MailQA improves inbox placement (practical guide)

    Email deliverability is a combination of sender reputation, recipient engagement, proper authentication, and email content quality. MailQA helps with each vector:

    1. Clean your list before sending

    Remove invalid addresses, disposable accounts, and catch-all domains that generate bounces. Every bounce negatively impacts your IP and domain reputation — verifying addresses beforehand prevents that.

    2. Fix authentication

    Ensure SPF, DKIM, and DMARC are configured correctly. MailQA checks and simulates authentication flows so deliverability issues due to misconfiguration are caught early.

    3. Avoid spam triggers

    Spam words, malformed headers, and suspicious links lead to spam folder placement. MailQA's spam-score engine identifies problematic content and gives recommendations to rewrite or remove elements that trigger filters.

    4. Monitor & iterate

    Use deliverability reports, bounce analytics, and blacklist monitoring to iterate on sending patterns, frequency, and content. Continuous improvement is the only reliable long-term strategy.

    5. Test previews on real clients

    Visual rendering issues reduce engagement. Preview emails on Gmail, Outlook desktop, Apple Mail, and mobile clients to avoid broken CTAs and images — factors that hurt conversion and engagement metrics used by inbox providers.

    This combined workflow (clean → authenticate → test → monitor) is the proven path to higher inbox placement and lower spam/complaint rates. MailQA provides the tooling for each step and the integrations to automate it.

    Frequently Asked Questions (FAQs)

    Answers to common questions about MailQA, email deliverability, and verification.

    What is MailQA?
    MailQA is an email testing, verification, and deliverability platform. It checks email syntax, validates domains, runs spam filters, previews rendering, and provides analytics to improve inbox placement.
    How does verification accuracy compare to others?
    MailQA uses layered checks (syntax, DNS/MX, SMTP probe, disposable list) and machine-learned heuristics to reach high accuracy. For actionable accuracy metrics, run a free sample with 100 credits.
    Does MailQA detect disposable and role-based emails?
    Yes. Disposable domains and role addresses are detected and flagged so you can decide to block or review them before sending.
    Do you provide inbox placement testing?
    Yes — MailQA simulates sends to seed inboxes and provides a placement report across major providers (Gmail, Outlook, Yahoo, etc.) and shows inbox vs spam hits.
    Can I preview on mobile and dark mode?
    Yes. Device previews include common mobile viewports and dark mode rendering so you can spot visual regressions.
    How do pricing credits work?
    Verification or test email credits are measured per action (1 verification = 1 credit; 1 preview may use credits depending on plan). Unused monthly credits do not roll over unless you have an enterprise agreement.
    Is there a free trial?
    Yes. New accounts receive 100 free credits to evaluate the API, verifier, and previews.
    Do you store email content?
    No — MailQA does not store email message bodies beyond transient processing and optional saved test cases. We encrypt data in transit and at rest.
    Can I run bulk CSV cleaning?
    Yes. Upload CSVs for bulk verification. The job returns a cleaned file with status and risk columns.
    Does MailQA check SPF, DKIM & DMARC?
    Yes. We report SPF alignment, DKIM signature validity, and DMARC policy status with actionable fixes.
    Is MailQA GDPR compliant?
    MailQA offers data processing agreements and supports data retention controls to meet GDPR obligations. Contact support for enterprise DPA details.
    Do you offer team accounts?
    Yes — Agency and Enterprise plans include team management, roles, and white-label reports.
    What integrations are available?
    API, Webhooks, Zapier, CSV import/export, and native connectors for popular CRMs and marketing tools (coming soon).
    How fast is the API?
    Typical verification latency is under 200ms for cached DNS checks; SMTP probes may take longer (up to a few seconds). Bulk jobs are asynchronous with webhook completion callbacks.
    What is your refund policy?
    We offer a 7-day refund window for paid plans. Enterprise agreements have custom terms.
    Can MailQA help with IP warmup?
    Yes. Enterprise customers get warmup guidance, deliverability consulting, and monitoring for IP reputation.
    How does MailQA compare to SpamAssassin?
    SpamAssassin is an open-source spam scoring engine. MailQA exposes SpamAssassin-like scoring along with broader checks (auth, blacklist, inbox placement) and developer-friendly APIs.
    Is there pay-as-you-go?
    Yes. Add extra verification packs or pay-as-you-go credits without upgrading your plan.
    Do you have SDKs?
    Official SDKs are available for Node and Python. Community SDKs for other languages are supported via examples in the docs.
    How do I get started?
    Sign up for a free account, use your 100 credits to run the verifier, and test a few email sends. Use the API key to integrate into your signup flow or marketing platform.
    Can MailQA replace Litmus or Mailtrap in my workflow?
    MailQA can replace parts of both: verification, spam scoring, deliverability analytics, and rendering previews. Evaluate with trial credits and check the comparison table above for exact feature parity you need.
